instructions from IBM for Google, Amazon and fb | killexams.com Real Questions and Pass4sure dumps

(MENAFN - The dialog) it's staggering when corporations ultimate for decades – or even more than a century – and especially so when they may be in a fast-altering business like desktop expertise. IBM, which traces its roots to the Eighties , grew from three small organizations to a multi-billion-dollar suggestions know-how capabilities business today. Its united statesand downs along the manner offer some insights into the global expertise business, and might contain some instructive instructions for up-and-coming digital giants like Google, Amazon and fb – all of that are far more youthful than IBM.

In my new booklet, ' IBM: the upward thrust and Fall and Reinvention of a worldwide Icon ,' I explore the enterprise's heritage of developing and selling facts processing machine and software. As a former IBM employee and a historian , probably the most vital lesson I found is that many people confuse incremental adjustments in technology with greater fundamental ones that in fact shape the course of a company's fate.

there's a difference between particular person items – successive models of PCs or typewriters – and the underlying applied sciences that make them work. Over a hundred thirty years, IBM released neatly over three,600 hardware products and basically the same amount of software . however all those gadgets and capabilities were in accordance with just a handful of actual technological advances, comparable to moving from mechanical machines to people who relied on computing device chips and utility, and later to networks like the information superhighway. The transitions between these advances took location much more slowly than the constant stream of new products may indicate.

These transitions from the mechanical, to the digital, and now to the networked reflected an ever-turning out to be potential to assemble and use better quantities of suggestions without problems and quickly. IBM moved from manipulating statistical data to the use of applied sciences that teach themselves what people want and are interested in seeing.

a spotlight that may adapt

Between 1914 and 1918, IBM administration decided that the company the enterprise would be in was information processing. in additional contemporary phrases, that enterprise has turn into 'massive statistics' and analytics. nonetheless it's nonetheless accumulating and organizing records, and performing calculations and computations on it.

on the grounds that the early Twenties, IBM has taken a disciplined method to product development and analysis, specializing in developing the underpinning applied sciences for its records processing products. Nothing gave the impression to be completed unintentionally.

A blue IBM punch card. Gwern/Wikimedia Commons

In its first half-century, IBM's primary technology platform from which many products emerged was the punch-card, yielding tabulators, card sorters, card readers and the famous IBM Card . In its second half-century, the primary technology platform changed into the desktop, including mainframes, minicomputers, PCs and laptops. In its most contemporary 30 years, computing device earnings have introduced in a declining share of the business's complete earnings, as IBM transitions to presenting more cyber web-primarily based functions, including software and technical and managerial consulting.

the upward thrust of each and every succeeding know-how happened throughout the maturity and decline of its predecessor. IBM first all started promoting computer systems within the Nineteen Fifties, however kept selling tabulating equipment that nonetheless used punch playing cards unless the early Nineteen Sixties. As these days as the early Nineties, over ninety p.c of IBM's revenues came from selling computers, although it turned into introducing new features like management and technique consulting, assistance technology management and software income.

It wasn't except the conclusion of 2018 that IBM announced that fifty percent of its enterprise now got here from services and application, most of that have been new offerings developed within the old decade.

The news media – and even IBM employees – may have perceived that IBM became transforming itself quickly and frequently . really the business had planted seeds for growth early and punctiliously tended new technologies unless they bore fruit – fortunately, across the same time as prior methods have been ending their positive lives.

This strategic method isn't amazing – Apple has been selling own computer systems for more than forty years . Its administration, of direction, talks plenty more about its function in the smartphone enterprise, which is already beginning to stage off . Apple may additionally soon need – or already be engaged on – a brand new technological center of attention to stay imperative.

The future of the giants

Microsoft, like Apple, evolved far from promoting just laptop software and operating techniques. It started web-based initiatives like its Bing search engine and OneDrive cloud storage – in addition to providing cloud-based mostly computing functions for groups.

IBM is already exploring quantum computing, as a brand new frontier of statistics processing. IBM research , CC via-ND

companies that began on the internet may additionally face identical transitions. Amazon, Google and fb now and then declare to have converted themselves, but have not yet utterly left their customary agencies.

Amazon nevertheless makes most of its funds selling physical items online, although its internet-based mostly cloud services division is starting to be hastily . Amazon has also invested in a big range of other business that may develop in the future, comparable to fitness care and enjoyment content.

Google and fb still make most of their money promoting counsel about how users behave to advertisers and corporations that are looking to appeal to americans to a selected factor of view. both are exploring other avenues, no matter if it be Google's self-driving automobiles or facebook's experiments with digital fact .

however at their core, all three web giants are still discovering new how you can capitalize on the large quantities of assistance they accumulate about shoppers' actions and interests – just as decades prior IBM discovered new easy methods to use tabulating equipment and computers. if they're to final many years or centuries into the longer term, the corporations will should probe, test and innovate to discover new tips on how to income as technologies alternate.

Microsoft simply hired a primary variety officer — and IBM is suing over it | killexams.com Real Questions and Pass4sure dumps

Tech agencies have a lower than stellar list hiring girls and minorities. but these companies will apparently do something it takes — including launching a prison battle — to rent one class of person: a first-rate diversity Officer.

IBM is suing its former correct range officer Lindsay-Rae McIntyre after she received poached by Microsoft, in a case that might show just how essential variety, recruitment, and retention has become for tech companies.

McIntyre, who joined IBM in 2006, became named chief range officer of Microsoft on Sunday, after serving within the identical position and as VP of human supplies at IBM. IBM, in its criticism, argues that McIntyree had access to diversity records, techniques, methodologies and initiatives that are confidential, and that she "will use, rely on or disclose" these ideas in her new function.

On Monday, IBM became granted a brief restraining order in new york federal courtroom, which prevents McIntyre from working for Microsoft until the court docket decides otherwise.

"McIntyre become at the middle of tremendously exclusive and competitively sensitive assistance that has fueled IBM's success in these areas," a consultant for IBM mentioned in an announcement. "whereas we bear in mind Microsoft's need to take care of mounting criticism of its record on variety, IBM intends to totally implement Ms. McIntyre's non-compete contract to offer protection to our competitive counsel."

at the heart of IBM's criticism is an on-going lawsuit from 2015, Moussouris v. Microsoft employer. The lawsuit alleges that Microsoft systematically discriminated in opposition t women in technical and engineering roles at the business when it got here to opinions, pay, and promotions.

The briefings for that lawsuit wrapped up on February 9. Now it's up to the courts to make a decision whether or now not the case has type-motion reputation.

As a part of its non-compete case, IBM is calling to make use of Microsoft's personal criminal arguments from the Moussouris lawsuit to make its own factor.

In April 2017, to steer clear of certain assistance from being launched publicly within the discovery process, Microsoft argued that such variety records is "no longer merely personal, but so delicate and doubtlessly destructive to Microsoft if published to its opponents (e.g., IBM), that the courtroom may still take the surprising measure of inserting the tips under seal," in keeping with IBM's complaint.

Microsoft in the end obtained some of the files in the case sealed, and others launched with redactions.

In its legitimate response to IBM, Microsoft argued that implementing McIntyre's non-compete contract is "draconian," as McIntyre has promised no longer to share private information with Microsoft.

it's worth noting that IBM's worker ranks aren't a paragon of variety: according to IBM's website, ladies comprised 31.8% of its international team of workers in 2016.

Back to Microservices with Istio (Part 1) | killexams.com real questions and Pass4sure dumps

Istio is an Open Source project developed in partnership between teams from Google, IBM, and Lyft and it provides a solution to the complexities of microservice based application, to name a few:

  • Traffic management: Timeouts, retries, load balancing,
  • Security: End-user Authentication and Authorization,
  • Observability: Tracing, monitoring, and logging.
  • All of these can be solved in the application layer, but your services don’t end up being so ‘Micro’ anymore, all the additional effort for implementing these is a strain in the company’s resources, resources that can be used to deliver business value. Let’s take an example:

    PM: How long will it take to add a feedback feature?

    Dev: Two sprints.

    PM: What…? That’s just a CRUD!

    Dev: Creating the CRUD is the easy part but then we need to authenticate and authorize users and services. And because the network is not reliable we need to implement retries, and circuit breakers in the clients, and to make sure that we do not take the whole system down we need Timeouts and Bulkheads, additionally to detect issues we need monitoring, tracing […]

    PM: Let’s just stick it in the Product Service then. Jeez!

    You get the idea, all the ceremony, and effort that must go in, for us to add one service is enormous. In this article, we’ll showcase how Istio removes all the above-mentioned cross-cutting concerns from our services.

    Figure 1. The Ceremony of a Microservice

    Note: This article assumes that you have a working knowledge of Kubernetes. If it’s not the case I recommend you to read my introduction to Kubernetes, and then continue with this article.

    The Idea of Istio

    In a world without Istio one service makes direct requests to another and in cases of failure, the service needs to handle it by retrying, timeouting, opening the circuit breaker etc.

    Figure 2. Network traffic in Kubernetes

    To resolve this, Istio provides an ingenious solution by being completely separated from the services and act only by intercepting all network communication. And doing so it can implement:

  • Fault Tolerance — Using response status codes it understands when a request failed and retries.
  • Canary Rollouts — Forward only the specified percentage of requests to a new version of the service.
  • Monitoring and Metrics — The time it took for a service to respond.
  • Tracing and Observability — It adds special headers in every request and traces them in the cluster.
  • Security — Extracts the JWT Token and Authenticates and Authorizes users.
  • To name a few (for real just a few) and get you intrigued! Let’s get to the Technical details!

    Istio’s Architecture

    Istio intercepts all network traffic and applies a set of rules by injecting an intelligent proxy as a sidecar in every pod. The proxies that enable all the features comprise The Data Plane and those are dynamically configurable by The Control Plane.

    The Data Plane

    The injected proxies enable Istio to easily achieve our requirements. For an example let’s check out the retrying and Circuit breaking functionalities.

    Figure 3. How envoys implement Retries & CircuitBreaking

    To summarize:

  • Envoy sends the request to the first instance of service B and it fails.
  • The Envoy Sidecar retries. (1)
  • Returns a failed request to the calling proxy.
  • Which opens the Circuit Breaker and calls the next Service on subsequent requests. (2)
  • This means that you don’t have to use another Retry library, you don’t have to develop your own implementation of Circuit Breaking and Service Discovery in Programming Language X, Y or Z. All of those and more are provided out of the box by Istio and NO code changes are required.

    Great! Now you want to join the voyage with Istio, but you still have some doubts, some open questions. Is this a One-Size-Fits-All-Solution, which you’re suspicious about, as it always ends up being One-Size-Fits None solution!

    You finally mutter the question: “Is this configurable?”

    Welcome to the cruise my friend and let’s get introduced to the Control Plane.

    The Control Plane

    Is composed of three components: The Pilot, the Mixer, and the Citadel that in combination configure Envoys to route traffic, enforce policies and collect telemetry data. Visually presented in the image below.

    Figure 4. Control Plane in relation to Data Plane

    The envoys (i.e. the data plane) are configured using Kubernetes Custom Resource Definitions defined by Istio and specialized for this purpose. Which means that for you it’s just another Kubernetes Resource with a familiar syntax. Which after being created will be picked up by the control plane that applies it to the envoys.

    Relation of Services to Istio

    We described the relation of Istio to our Services, but not the other way around, what’s the relation of our Services to Istio?

    Frankly, our services have as much knowledge of Istio’s presence, as fish do of water, they will ask themselves “What the hell is water?”.

    Drawing by Victoria Dimitrakopoulos

    This means that you can pick a working cluster and after deploying the components of Istio, the services within will continue to work and in the same manner, you can remove the components and everything will be just fine. Understandably, you would lose the capabilities provided by Istio.

    We had enough of theory, let’s put this knowledge into practice!

    Istio in Practice

    Istio requires a Kubernetes Cluster with at least 4 vCPU and 8 GB of RAM. To quickly set up a cluster and follow up with this article, I recommend using the Google Cloud Platform, which provides new users with a $300 free trial.

    After creating the cluster and configuring access with the Kubernetes command line tool we’re ready to install Istio using the Helm Package manager.

    Installing Helm

    Install the Helm client on your computer as explained in the official docs. Which we will use to generate the Istio installation templates in the next section.

    Installing Istio

    Download Istio’s resources from the latest release, extract the contents into one directory that we will refer to as [istio-resources].

    To easily identify the Istio resources create a namespace istio-system in your Kubernetes Cluster:

    $ kubectl create namespace istio-system

    Complete the installation by navigating to [istio-resources] directory and executing the command below:

    $ helm template install/kubernetes/helm/istio \--set global.mtls.enabled=false \--set tracing.enabled=true \--set kiali.enabled=true \--set grafana.enabled=true \--namespace istio-system > istio.yaml

    The above command prints out the core components of Istio into the file istio.yaml. We customized the template using the following parameters:

  • global.mtls.enabled is set to false to keep the introduction focused.
  • tracing.enabled enables tracing of requests using jaeger.
  • kiali.enabled installs Kiali in our cluster for Visualizing Services and Traffic
  • grafana.enabled installs Grafana to visualize the collected metrics.
  • Apply the generated resources by executing the command:

    $ kubectl apply -f istio.yaml

    This marks the completion of the Istio installation in our cluster! Wait until all pods in the istio-system namespace are in Running or Completed state by executing the command below:

    $ kubectl get pods -n istio-system

    Now we’re ready to continue with the next section, where we will get the sample application up and running.

    Sentiment Analysis Application Architecture

    We will use the same microservice application used in the Kubernetes Introduction article, it’s complex enough to showcase Istio’s features in practice.

    The App is composed of four microservice:

  • SA-Frontend service: Serves the frontend Reactjs application.
  • SA-WebApp service: Handles requests for Sentiment Analysis.
  • SA-Logic service: Performs sentiment analysis.
  • SA-Feedback service: Receives feedbacks from the users about the accuracy of the analysis.
  • Figure 6 Sentiment Analysis microservices

    In figure 6, besides the services we see the Ingress Controller which in Kubernetes routes incoming requests to the appropriate services, Istio uses a similar concept called Ingress Gateway, which will be introduced in continuation of the article.

    Running the Application with Istio Proxies

    To follow up with this article clone the repository istio-mastery, containing the application and the manifests for Kubernetes and Istio.

    Sidecar Injection

    The injection is done Automatically or Manually. To enable automatic sidecar injection, we need to label the namespace with istio-injection=enabled, by executing the command below:

    $ kubectl label namespace default istio-injection=enablednamespace/default labeled

    From now every pod that gets deployed into the default namespace will get the sidecar injected. To verify this let’s deploy the sample application by navigating to the root folder of the [istio-mastery] repository and executing the following command:

    $ kubectl apply -f resource-manifests/kubepersistentvolumeclaim/sqlite-pvc createddeployment.extensions/sa-feedback createdservice/sa-feedback createddeployment.extensions/sa-frontend createdservice/sa-frontend createddeployment.extensions/sa-logic createdservice/sa-logic createddeployment.extensions/sa-web-app createdservice/sa-web-app created

    With the services deployed verify that the pods have two containers (the service and the sidecar) by executing the command kubectl get pods and ensuring that under the column ready, we see the value “2/2” indicating that both containers are running. As seen below:

    $ kubectl get podsNAME READY STATUS RESTARTS AGEsa-feedback-55f5dc4d9c-c9wfv 2/2 Running 0 12msa-frontend-558f8986-hhkj9 2/2 Running 0 12msa-logic-568498cb4d-2sjwj 2/2 Running 0 12msa-logic-568498cb4d-p4f8c 2/2 Running 0 12msa-web-app-599cf47c7c-s7cvd 2/2 Running 0 12m

    Visually presented in figure 7.

    Figure 7. Envoy proxy in one of the Pods

    With the application up and running now we need to allow incoming traffic to reach our application.

    Ingress Gateway

    A best practice for allowing traffic into the cluster is through Istio’s Ingress Gateway which positions itself at the edge of the cluster and on incoming traffic enables Istio’s features like routing, load balancing, security, and monitoring.

    During Istio’s installation, the Ingress Gateway component and a service that exposes it externally were installed into the cluster. To get the services External IP execute the command below:

    $ kubectl get svc -n istio-system -l istio=ingressgatewayNAME TYPE CLUSTER-IP EXTERNAL-IPistio-ingressgateway LoadBalancer

    In the continuation of this article we will access the application on this IP (referred to as the EXTERNAL-IP), for convenience, save it in a variable by executing the command below:

    $ EXTERNAL_IP=$(kubectl get svc -n istio-system \-l app=istio-ingressgateway \-o jsonpath='{.items[0].status.loadBalancer.ingress[0].ip}')

    If you reach this IP in your browser and you will get a Service Unavailable error, as by default Istio blocks any incoming traffic until we define a Gateway.

    The Gateway Resource

    A Gateway is a Kubernetes Custom Resource Definition defined upon Istio’s installation in our cluster that enables us to specify the Ports, Protocol and Hosts for which we want to allow incoming traffic.

    In our scenario, we want to allow HTTP traffic on port 80, for all hosts. Achieved with the following definition:

    All the configuration is self-explanatory besides the selector istio: ingressgateway. Using this selector, we can specify to which Ingress Gateway to apply the configuration, and in our case, it’s the default ingress gateway controller installed on Istio setup.

    Apply the configuration by executing the command below:

    $ kubectl apply -f resource-manifests/istio/http-gateway.yaml gateway.networking.istio.io/http-gateway created

    The gateway now allows access in port 80 but it has no concept where to route the requests. That is achieved using Virtual Services.

    The VirtualService resource

    The VirtualService instructs the Ingress Gateway how to route the requests that were allowed into the cluster.

    For our application requests coming through the http-gateway must be routed to the sa-frontend, sa-web-app and sa-feedback services (show in figure 8).

    Figure 8. Routes to be configured with VirtualServices

    Let’s break down the requests that should be routed to SA-Frontend:

  • Exact path /should be routed to SA-Frontend to get the Index.html
  • Prefix path /static/* should be routed to SA-Frontend to get any static files needed by the frontend, like Cascading Style Sheets and JavaScript files.
  • Paths matching the regex '^.*\.(ico|png|jpg)$' should be routed to SA-Frontend as it is an image, that the page needs to show.
  • This is achieved with the following configuration:

    The important points here are:

  • This VirtualService applies to requests coming through the http-gateway.
  • Destination defines the service where the requests are routed to.
  • Note: The configuration above is in the file sa-virtualservice-external.yaml, it also contains the configuration to route to SA-WebApp and SA-Feedback but was shortened for brevity.

    Apply the VirtualService by executing:

    $ kubectl apply -f resource-manifests/istio/sa-virtualservice-external.yamlvirtualservice.networking.istio.io/sa-external-services created

    Note: When we apply Istio resources the Kubernetes API Server creates an event received by Istio’s Control Plane which then applies the new configuration to the envoy proxies of every pod. And the Ingress Gateway controller is another Envoy which is configured by the Control Plane, visually presented in figure 9.

    Figure 9. Configuring Istio-IngressGateway to route requests

    The Sentiment Analysis app is now accessible on http://{EXTERNAL-IP}/. If you get a Not Found status, do not worry sometimes it takes a bit for the configuration to go in effect and update the envoy caches.

    Before moving to the next section use the app to generate some traffic.

    Kiali — Observability

    To access Kiali’s Admin UI execute the command below:

    $ kubectl port-forward \$(kubectl get pod -n istio-system -l app=kiali \-o jsonpath='{.items[0].metadata.name}') \-n istio-system 20001

    And open http://localhost:20001/ login using “admin” (without quotes) for user and password. There is a ton of useful features, for example checking the configurations of Istio Components, visualizing services according to the information collected by intercepting network requests and answering, “who is calling who?”, “which version of a service has failures?” etc. Take some time to checkout Kiali before moving on to the next goodie, visualizing metrics with Grafana!

    Figure 10. Kiali — Service Observability Grafana — Metrics Visualization

    The metrics collected by Istio are scraped into Prometheus and Visualized using Grafana. To access the Admin UI of Grafana execute the command below and open http://localhost:3000.

    $ kubectl -n istio-system port-forward \$(kubectl -n istio-system get pod -l app=grafana \-o jsonpath={.items[0].metadata.name}) 3000

    On the top left click the menu Home and select Istio Service Dashboard and on the top left corner select the service starting with sa-web-app, you will be presented with the collected metrics, as seen on the image below:

    Holly molly that’s an empty and totally non-exciting view, management would never approve of this. Let’s cause some load by executing the command below:

    $ while true; do \curl -i http://$EXTERNAL_IP/sentiment \-H “Content-type: application/json” \-d ‘{“sentence”: “I love yogobella”}’; \sleep .8; done

    Now we have prettier graphs 😊, and additionally, we have the amazing tools of Prometheus for monitoring and Grafana for visualizing the metrics that enable us to know the performance, health, improvement or degradation of our services throughout time!

    Lastly, we will investigate Tracing requests throughout services.

    Jaeger — Tracing

    We need tracing because the more services we have the harder it gets to pinpoint the cause of failure. Let’s take the simple case in the image below:

    Figure 12. A commonly random failed request

    The request goes in, failure goes out, what was the cause? The first service? Or the second? Exceptions are in both, Let’s get down to the logs of each. How many times do you find yourself doing this? Our job feels more like Software Detectives than Developers.

    This is a prevalent problem in Microservices and it’s solved using Distributed Tracing Systems where the services pass a unique header to each other and then this information is forwarded to the Distributed Tracing System where the request trace is put together. An example is shown in figure 13.

    Figure 13. TraceId used to identify the span of a request

    Istio uses Jaeger Tracer that implements the OpenTracing API, a vendor-neutral framework. To get access the Jaegers UI execute the command below:

    $ kubectl port-forward -n istio-system \$(kubectl get pod -n istio-system -l app=jaeger \-o jsonpath='{.items[0].metadata.name}') 16686

    Then open the UI in http://localhost:16686, select the sa-web-app service, if the service is not shown on the dropdown generate some activity on the page and hit refresh. Afterward click the button Find Traces, which displays the most recent traces, select any and a detailed breakdown of all the traces will be shown, as seen in figure 14.

    Figure 14. Jaeger — a request trace

    The trace shows:

  • The request comes to the istio-ingressgateway (it’s the first contact with one of the services so for the request the Trace ID is generated) then the gateway forwards the request to the sa-web-app service.
  • In the sa-web-app service, the request is picked up by the Envoy sidecar and a span child is created (that’s why we see it in the traces) and forwarded to the sa-web-app container instance.
  • Here the method sentimentAnalysis handles the request. These traces are generated by the application, meaning that code changes were required).
  • From where a POST request is started to sa-logic. Trace ID needs to be propagated by sa-web-app.
  • 5. …

    Note: At the 4th point our application needs to pick up the headers generated by Istio and pass them down on the next requests, as shown in the image below.

    Figure 15. (A) Istio propagating headers, (B) Services propagating headers

    Istio does the main heavy lifting as it generates the headers on incoming requests, creates new spans on every sidecar, propagates them, but without our services propagating the headers as well, we will lose the full trace of the request.

    The headers to propagate are:


    Despite it being a simple task, there are already many libraries that simplify the process, for example in the sa-web-app service, the RestTemplate client is instrumented to propagate the headers by simply adding the Jaeger and OpenTracing libraries in the dependencies.

    Note: The Sentiment Analysis app showcases implementations for Flask, Spring and ASP.NET Core.

    Now after investigating what we get out of the box (or partially out of the box 😜) let’s get to the main topic here, fine-grained routing, managing network traffic, security and more!

    Traffic Management

    Using the Envoy’s Istio provides a host of new capabilities to your cluster enabling:

  • Dynamic request routing: Canary deployments, A/B testing,
  • Load balancing: Simple and Consistent Hash balancing,
  • Failure Recovery: Timeouts, retries, circuit breakers,
  • Fault Injection: Delays, abort requests etc.
  • In the sequence of this article, we’ll showcase these capabilities in our application and get introduced to new concepts along the way. The first concept we will delve into is DestinationRules and using those we’ll enable A/B Testing.

    A/B Testing — Destination Rules in Practice

    A/B Testing is used when we have two versions of an application (usually the versions differ visually) and we aren’t 100% sure which will increase user interaction, so we try both versions at the same time and collect metrics.

    Execute the command below to deploy a second version of the frontend, needed for demonstrating A/B Testing:

    $ kubectl apply -f resource-manifests/kube/ab-testing/sa-frontend-green-deployment.yamldeployment.extensions/sa-frontend-green created

    The deployment manifest for the green version differs in two points:

  • The image is based on a different tag: istio-green and
  • Pods are labeled with version: green.
  • And as both deployments have the label app: sa-frontend requests routed by the virtual service sa-external-services to the service sa-frontend will be forwarded to all of its instances and will be load balanced using the round robin algorithm, which causes the issue presented in figure 16.

    Figure 16. Requested files are not found

    The files are not found because they are named differently in the different versions of the app. Let’s verify that:

    $ curl --silent http://$EXTERNAL_IP/ | tr '"' '\n' | grep main/static/css/main.c7071b22.css/static/js/main.059f8e9c.js$ curl --silent http://$EXTERNAL_IP/ | tr '"' '\n' | grep main/static/css/main.f87cd8c9.css/static/js/main.f7659dbb.js

    This means that the index.html that requests one version of the static files might be load balanced to the pods delivering the other version, where understandably the other files do not exist.

    This means that for our app to work we need to introduce the restriction that “the version of the app that served the index.html, must serve subsequent requests”.

    We’ll achieve this using Consistent Hash Loadbalancing, which is the process that forwards requests from the same client to the same backend instance, using a predefined property, like for example an HTTP header. Made possible by DestionatioRules.


    After a request gets routed by the VirtualService to the correct service, then using DestinationRules we can specify policies that apply to the traffic intended for the instances of this Service, as seen in figure 17.

    Figure 17. Traffic Management with Istio Resources

    Note: Figure 17, visualizes how Istio resources are affecting the network traffic, in an easily understandable way. But, to be precise the decision to which instance to forward the request to is made in the Ingress Gateway’s Envoy, configured by the CRDs.

    Using Destination Rules we can configure load balancing to have consistent hashing and ensure that the same user is responded by the same instance of the service. Achieved with the following configuration:

  • Generate a consistent hash according to the contents of the “version” header.
  • Apply the configuration by executing the command below and give it a try!

    $ kubectl apply -f resource-manifests/istio/ab-testing/destinationrule-sa-frontend.yamldestinationrule.networking.istio.io/sa-frontend created

    Execute the command below and verify that you get the same files when specifying the version header:

    $ curl --silent -H "version: yogo" http://$EXTERNAL_IP/ | tr '"' '\n' | grep main

    Note: You can use this chrome extension to add different values to the version header, to test in your browser.

    DestinationRules have more LoadBalancing capabilities, for all the details check out the official docs.

    Before moving on to explore VirtualService in more detail, remove the green version of the app and the destination rule by executing the commands below:

    $ kubectl delete -f resource-manifests/kube/ab-testing/sa-frontend-green-deployment.yamldeployment.extensions “sa-frontend-green” deleted$ kubectl delete -f resource-manifests/istio/ab-testing/destinationrule-sa-frontend.yamldestinationrule.networking.istio.io “sa-frontend” deleted Shadowing — Virtual Services in Practice

    Shadowing or Mirroring is used when we want to test a change in production but not affect end-users, so we mirror the requests into a second instance that has the change and evaluate it. To phrase it simpler it’s when one of your colleagues picks the most critical issue and makes a Big ball of mud Pull Request, that nobody can really review.

    To test out this feature lets create a second instance of SA-Logic (which is buggy) by executing the command below:

    $ kubectl apply -f resource-manifests/kube/shadowing/sa-logic-service-buggy.yamldeployment.extensions/sa-logic-buggy created

    Execute the following command and verify that all instances are labeled with the respective versions and additionally with app=sa-logic:

    $ kubectl get pods -l app=sa-logic --show-labelsNAME READY LABELSsa-logic-568498cb4d-2sjwj 2/2 app=sa-logic,version=v1sa-logic-568498cb4d-p4f8c 2/2 app=sa-logic,version=v1sa-logic-buggy-76dff55847-2fl66 2/2 app=sa-logic,version=v2sa-logic-buggy-76dff55847-kx8zz 2/2 app=sa-logic,version=v2

    As the service sa-logic targets pods labeled with app=sa-logic, any incoming requests will be load balanced between all instances, as shown in figure 18.

    Figure 18. Round Robin load balancing

    But we want requests to be routed to the instances with version v1 and mirrored to the instances with version v2, as shown in figure 19.

    Figure 19. Routing to v1 and Mirroring to v2

    This is achieved using a VirtualService in combination with a DestinationRule, where the destination rule specifies the subsets and VirtualService routes to the specific subset.

    Specifying Subsets with Destination Rules

    We define the subsets with the following configuration:

  • Host defines that this rule applies only when routing has occurred towards sa-logic service
  • Subset name used when routing to instances of a subset.
  • Label defines the key-value pairs that need to match for an instance to be part of the subset.
  • Apply the configuration executing the command below:

    $ kubectl apply -f resource-manifests/istio/shadowing/sa-logic-subsets-destinationrule.yamldestinationrule.networking.istio.io/sa-logic created

    With the subsets defined we can move on and configure a VirtualService to apply to requests towards sa-logic where the requests are:

  • Routed to the subset named v1 and,
  • Mirrored to the subset named v2.
  • And this is achieved with the manifest below:

    As everything is self-explanatory let’s just see it in action:

    $ kubectl apply -f resource-manifests/istio/shadowing/sa-logic-subsets-shadowing-vs.yamlvirtualservice.networking.istio.io/sa-logic created

    Add some load by executing the following command:

    $ while true; do curl -v http://$EXTERNAL_IP/sentiment \-H “Content-type: application/json” \-d ‘{“sentence”: “I love yogobella”}’; \sleep .8; done

    Check the results in Grafana, where we can see that the buggy version is failing about 60% of the requests, but none of the failures affected the end-users as they were responded by the currently active service.

    Figure 20. The success rate of sa-logic service versions

    In this section, we saw for the first time a VirtualService that was applied to the envoys of our services, when the sa-web-app makes a request towards sa-logic this goes through the sidecar envoy, which via the VirtualService is configured to route to the subset v1 and mirror to the subset v2 of the sa-logic service.

    I can see you thinking “Darn man Virtual Services are simple!”, in the next section, we’ll extend the sentence to “Simply Amazing!”.

    Canary Deployments

    Canary Deployment is the process of rolling out a new version of an application to a small set of users, as a step to verify the absence of issues, and then with a higher assurance of quality release to the wider audience.

    We will continue with the same buggy subset of sa-logic to demonstrate canary deployments.

    Let’s start boldly and send 20% of the users to the buggy version (this represents the canary deployment) and 80% to the healthy service by applying the VirtualService below:

  • Weight specifies the percentage of requests to be forwarded to the destination or subset of the destination.
  • Update the previous sa-logic virtual service configuration using the following commands:

    $ kubectl apply -f resource-manifests/istio/canary/sa-logic-subsets-canary-vs.yamlvirtualservice.networking.istio.io/sa-logic configured

    We immediately see that some of our requests are failing:

    $ while true; do \curl -i http://$EXTERNAL_IP/sentiment \-H “Content-type: application/json” \-d ‘{“sentence”: “I love yogobella”}’ \--silent -w “Time: %{time_total}s \t Status: %{http_code}\n” \-o /dev/null; sleep .1; doneTime: 0.153075s Status: 200Time: 0.137581s Status: 200Time: 0.139345s Status: 200Time: 30.291806s Status: 500

    VirtualServices enable Canary Deployments and with this method, we reduced potential damages to 20% of our user base. Beautiful! Now we can use Shadowing and Canary Deployments every time we are insecure about our code, in other words always. 😜

    Timeouts & Retries

    It’s not always that the code is buggy. In the list of “The 8 fallacies of distributed computing” the first fallacy is that “The network is reliable”. The network is NOT reliable, and that’s why we need Timeouts and Retries.

    For demonstration purposes, we will continue to use the buggy version of sa-logic, where the random failures simulate the unreliability of the network.

    The buggy service has a one-third chance of taking too long to respond, one-third chance of ending in an Internal Server Error and the rest complete successfully.

    To alleviate these issues and improve the user experience we can:

  • Timeout if the service takes longer than 8 seconds and
  • Retry on failed requests.
  • This is achieved with the following resource definition:

  • The request has a timeout of 8 seconds,
  • It attempts 3 times,
  • An attempt is marked as failed if it takes longer than 3 seconds.
  • This is an optimization, as the user won’t be waiting for longer than 8 seconds and we retry three times in case of failures, increasing the chance of resulting in a successful response.

    Apply the updated configuration with the command below:

    $ kubectl apply -f resource-manifests/istio/retries/sa-logic-retries-timeouts-vs.yamlvirtualservice.networking.istio.io/sa-logic configured

    And check out the Grafana graphs for the improvement in success rate (shown in figure 21).

    Figure 21. Improvement after using Timeouts & Retries

    Before moving into the next section delete sa-logic-buggy and the VirtualService by executing the command below:

    $ kubectl delete deployment sa-logic-buggydeployment.extensions “sa-logic-buggy” deleted$ kubectl delete virtualservice sa-logicvirtualservice.networking.istio.io “sa-logic” deleted Circuit Breaker and Bulkhead patterns

    Two important patterns in Microservice Architectures that enable self-healing of the services.

    The Circuit Breaker is used to stop requests going to an instance of a service deemed as unhealthy and enable it to recover, and in the meantime client’s requests are forwarded to the healthy instances of that service (increasing success rate).

    The Bulkhead pattern isolates failures from taking the whole system down, to take an example, Service B is in a corrupt state and another service (a client of Service B) makes requests to Service B this will result that the client will use up its own thread pool and won’t be able to serve other requests (even if those are not related to Service B).

    I will skip implementations of these patterns because you can check out implementations in the official docs and I’m way too excited to showcase Authentication and Authorization, which will be the subject of the next article.

    Part I — Summary

    In this article, we deployed Istio in a Kubernetes cluster and using its Custom Resource Definitions like Gateways, VirtualServices, DestinationRules and it’s components it enabled the following features:

  • Observability over our services by answering what services are running, how are they performing and how are they related, using Kiali.
  • Metric collection and visualization, with Prometheus and Grafana.
  • Request tracing with Jaeger (german for Hunter).
  • Full and fine-grained control over the network traffic, enabling Canary Deployments, A/B Testing, and Shadowing.
  • Easy implementation of Retries, Timeouts, and CircuitBreakers.
  • And all were possible without code changes or any additional dependencies, keeping your services small, easy to operate and maintain.

    For your development team removing these cross-cutting concerns and centralizing them into Istio’s Control plane, means that new services are easy to be introduced, they aren’t resource-heavy as developers can focus in solving business problems. And up to now, no developer complained about “having to solve interesting business problems!”.

    I would love to hear your thoughts in the comments below and feel free to reach out to me on Twitter or on my page rinormaloku.com, and stay tuned for the next article where we tackle the final layers of Authentication and Authorization!

    Oracle Releases GraalVM 1.0, a Polyglot Virtual Machine and Platform | killexams.com real questions and Pass4sure dumps

    Oracle has announced the 1.0 release of GraalVM, a polyglot virtual machine and platform. The initial release includes the capability to run Java and JVM languages (via bytecode) as well as full support for JavaScript and Node.JS, with beta support for Ruby, Python, R and LLVM bitcode.

    The overall platform comprises a number of components:

  • Graal - a JIT compiler written in Java
  • SubstrateVM - a lightweight wrapper to abstract away the execution container
  • Truffle - a toolkit and API for building language interpreters
  • The overall intent is to provide a polyglot language execution environment that can be embedded within another execution container - either an OpenJDK container or another possibility, such as within an Oracle or MySQL database.

    InfoQ spoke to Thomas Wuerthinger, research director at Oracle Labs, for an in-depth interview about GraalVM.

    InfoQ: Can you explain the history of GraalVM? Where did it come from?

    Thomas Wuerthinger: The big idea was that a compiler didn't have to have any built-in knowledge of the language semantics. The reason for this was that it was very clear from the beginning that groups within Oracle had interest in a very diverse range of languages including JavaScript, R and Ruby.

    There were two key areas we felt we could improve upon with some exploration:

  • The common belief of VM architects throughout the software industry at that time was that a language VM needed to be designed specifically with the semantics of the language in mind if you wanted to get optimal performance.
  • The Java architects worked to support multilingualism starting in Java 7 by conversions to Java bytecode by adding `invokedynamic` to the JVM specification. The GraalVM team felt that since Java bytecode had too much Java semantics built into it, a longer term effort could be much more efficient and a 100% compatible implementation at that.
  • We also had the goal of demonstrating a fully-multilingual engine with competitive performance, and we started off some collaborations with universities to work on other languages.

    A group at Purdue did an implementation of R, and a group at UC Irvine did an implementation of Python in 2012-2014. A student intern worked on Ruby as a thesis project, and it had enough weird and interesting properties that we thought it was a good proof point that our multilingual compiler was fully general. Later we brought those language projects into Oracle Labs to get an industrial-quality implementation for those languages.

    With the release of GraalVM 1.0, we feel that we have demonstrated both that a multilingual VM with competitive performance is possible, and that the best way to do it isn't through a language-specific bytecode like Java or Microsoft CLR.

    InfoQ: What are the key technologies that make up GraalVM? How will they help developers?

    Wuerthinger: The key technology idea in GraalVM is called "Partial Evaluation", which is a technique for converting interpreters into compilers automatically. This allows you to build new languages very quickly. Language developers can focus on just building an [Abstract Syntax Tree] AST interpreter, and do not have to worry about writing a code generator or other low-level runtime functionality like a garbage collector.

    A key technology we built into GraalVM is logical/physical data separation. This allows any memory data layout to be made to appear like a local language object. Most VMs have a specific layout for objects (with object headers often called "boxes"), and to have the semantics of an object in the language, your data has to have the same layout.

    This means that you have to allocate memory and copy data to be an "object" in most VMs.

    In Graal, you can have zero-cost interop between languages, because a JavaScript object can be made to behave like a JavaScript object or an R object or whatever, without the need for additional object creation & data copies.

    This also allows, for example, exposing data from a custom binary format in the form of high-level objects to a program without ever actually allocating those high-level objects.

    Another key technology is our LLVM interpreter. We have a GraalVM interpreter for LLVM bitcode, which is the output of the popular LLVM compiler, which works well with languages targeting native binaries (like C++, FORTRAN, Rust, and so forth).

    One of the key problems in implementing languages is that they usually have libraries that are implemented in native code (usually C/C++), and they use an API that exposes some amount of the language internals. So, if you want to be compatible with a language ecosystem, you have to support its native libraries.

    One of the problems with implementations like JRuby or Nashorn is that they don't work for modules containing native parts, which is a problem for compatibility.

    A final and separate technology piece of GraalVM that was added later is called SubstrateVM. The idea here was to make VMs embeddable on a mix and match basis. A conventional language VM like Java Hotspot wants to control everything: which threads are scheduled, how memory allocations are parcelled out to those threads, access to the OS, etc.

    We wanted a technology layer that would allow an underlying system to provide some of those services, with SubstrateVM making up the missing pieces in terms of what is needed to support a dynamic JIT compiler (like a garbage collector). When you are running in a database, for example, the database wants to control memory management, thread allocations, and so forth.

    SubstrateVM is the "wafer-thin" VM that can sit on something like a database, so when you run the Graal compiler there, the database can specify the maximum heap size rather than the Java mechanism, and the database can manage code artefacts rather than the JVM class loader, and so forth.

    One of the important ways the SubstrateVM operates is to do ahead-of-time compilation on Java code (like Graal) directly into a native binary, using a closed world assumption (all the classes to be used should be known at compile time). So, when you deploy the Graal compiler in a database, we take Graal and some set of GraalVM languages and compile them into a native shared library, and they don't have to be compiled at runtime.

    InfoQ: What is Truffle? Why is it needed?

    Wuerthinger: Truffle is the API you have to write a GraalVM interpreter to, when you are building a new GraalVM language. The way interpreters work is that they first parse source code into what is called an Abstract Syntax Tree or AST. For example, if you wrote code like: c = a + b then the AST would contain two nodes, one for the add operator and having child nodes of a and b, and a second one for the assignment having child nodes of c and the add operator node.

    The interpreter internals like the AST need to be inherited from Truffle interfaces, and if you do so, the Graal compiler will watch the activity of the language interpreter to learn the semantics of the language, so that a compiler for that language can be generated.

    InfoQ: One of GraalVM's most visible components is the Graal compiler - a Java-based JIT compiler, just known as "Graal". Can you speak to some of the difficulties that are present in C2 (the existing C++ JIT in OpenJDK) that Graal is looking to move past? Is it expected that Graal will replace C2 / Tiered Compilation as default in the mainline OpenJDK?

    Wuerthinger: The Graal compiler is an experimental compiler in Java 10 and Oracle is optimistic that it can be the default in a future release.

    The big advantage that a compiler like Graal has is that it first compiles itself (since it is written in Java), and that makes it possible to write Graal in a much higher-level way than working directly on the AST in C++ as C2 does. For example, this makes it easier for Graal to do more aggressive inlining and object escape analysis, which allows more object allocations to be removed from the program automatically. In general, the more abstractions your program has, the more the Graal compiler helps you, so you see the biggest performance benefits in things like the Stream & Lambda support in Java8 or in Scala.

    InfoQ: Oracle is heavily marketing GraalVM as a polyglot VM. How does the content of the 1.0 release differ to what was shipped as part of Java 10? Should, for example, JRuby developers choose one release over the other? Is GraalVM seen as a separate project, or a part of OpenJDK? Will future releases of Graal be tied to the Java release cadence, or is it seen as independent?

    Wuerthinger: GraalVM and Java are 100% independent projects with large open source presence and with separate release cadences, and they both grab pieces of technology from each other. Java 10 is grabbing the compiler from GraalVM (as an experimental option), and GraalVM inbounds the bulk of Java 8 as one of the supported languages. GraalVM inbounds lots of languages, not just Java, so we use technology from Node.js, JRuby, and from the GNU R implementation, among others.

    Like most technology producer/consumer relationships across organizations, the consumer waits for new technology from others to stabilize before including it. Similarly, The Java Platform Group has to be conservative about including new technology until they are sure it won't break existing deployments, and they have lots of backwards and forwards compatibility concerns, so there is going to be some lag.

    InfoQ: IBM's OpenJ9 runtime takes a rather different approach to GraalVM. Can you explain the main differences between OpenJ9 / OMR as you see them, and speak to what makes GraalVM unique?

    Wuerthinger: OpenJ9 is trying to speed up existing single language runtimes (like Ruby MRI) by adding some limited just-in-time compilation functionality to them. The advantage of their approach is that it is easier to fit into an existing runtime while staying compatible. The major disadvantage however is that the benefits are much more limited.

    First, the performance benefit of their Ruby prototype is very small compared to the order of magnitude Ruby running on GraalVM achieves. The reason is that GraalVM works with much more profiling and speculative optimizations while OMR keeps the data structures of the existing interpreter.

    Second, they require you to write a code generator and cannot automatically derive the compiled code from the interpreter via partial evaluation.

    Third, there is no built-in physical/logical data separation.

    This leads to most important fourth point: there is no ability with their approach for efficient language interoperability.

    OMR can give marginal improvement to existing single-language runtimes like Ruby MRI that are not well-optimized already. GraalVM uses a completely new way to write languages with an order of magnitude improvement and polyglot capabilities to run any set of languages with zero overhead interoperability.

    InfoQ: What about wider community involvement in Graal? Twitter are on record as being early adopters and running Graal in production - who else is already using it? What has been your experience of working with non-Oracle developers? What does the future development of Graal look like? Will it adopt a similar model to OpenJDK as a whole?

    Wuerthinger: OpenJDK has a very different mission than GraalVM.

    OpenJDK has a large surface area for developers, since it is creating new language features and new libraries all the time. You have to change your code to deal with many of the changes to OpenJDK, and the mission is to get community consensus on which changes are worthwhile. The OpenJDK community is very large and there are a lot of opinions, and their process helps get to community consensus.

    GraalVM is about making code in languages and libraries that already exist run more efficiently, in more places, and interoperate more, and not to change language semantics (for the most part). The only major piece of developer interface it has is the interoperabity API that allows you to invoke foreign language functions in other runtimes, and we try to stay below the waterline as much as possible.

    The community for each language that GraalVM supports comes to its own conclusions on how it should evolve.

    As with OpenJDK, GraalVM has a lot of great contributions from vendors like Red Hat, Intel and AMD that are quite substantial. Red Hat took the initiative a while ago to build an ARM backend for GraalVM without much input from us, and that turned out to be very useful for us. You may be aware that Oracle invested in an ARM vendor recently, so now we are paying more attention to that ecosystem.

    Those vendors believe that GraalVM will get enough uptake from others to warrant the investments, and their interest isn't primarily for their own usage. As you point out, Twitter has been contributing to GraalVM because they are using it themselves. There are some other major technology vendors using it that aren't going public the way Twitter has, and we have internal users at Oracle.

    InfoQ: Oracle is usually reticent to discuss future roadmaps. Can you give us any indication of where the development track of GraalVM might take us in the next 18 months?

    Wuerthinger: Well, the GraalVM team is in Oracle Labs, so we have kind of the opposite problem where we have lots of research projects that are public that may or may not go anywhere beyond a paper in an academic conference. Oracle Labs has a cloud of graduate student collaborators looking to try out ideas using GraalVM.

    We have one student who was thinking about linking GraalVM into Chromium so that you could use any language in the browser and not just JavaScript, but I think it is very clear that it is unlikely ever to be released as an Oracle product. You can certainly look for academic papers based on GraalVM to see some other crazy ideas. We've done investigations into some other languages as research projects that may or may not go anywhere, based on community interest.

    What I can tell you about the roadmap is that we are working on supporting more platforms. The initial release was just for a Linux/X86 and Mac/X86 to minimise the "release stress". We are actively working on Windows support and also on support for the ARM platform (together with Red Hat). There is also quite some stabilisation and completeness work necessary for the languages that are currently marked as "experimental"  i.e., R, Ruby, and Python.

    In terms of integrations, there are a number of ways that we are going to integrate GraalVM more deeply into MySQL and the Oracle RDBMS that you will see in the next 18 months. But how GraalVM will look like in 18 months will also very much depend on the overall community feedback and contributions.

    This article was contributed by Stacey Quandt

    The 13th annual International Linux System Technology Conference, also known as Linux Kongress, took place September 5 - 8 in Nürnberg, Germany. As a technical Linux event Linux Kongress is smaller in scale than the Ottawa Linux Symposium and linux.conf.au. Still the conference sessions and tutorials included a number of quality talks from familiar members of the Linux and open source communities such as Heinz Mauelshagen, Lars Mueller, Theodore Ts'o, Volker Lendecke, Alan Robertson, and Daniel Phillips.

    A few of the talks stood out. One such talk was Felix von Leitner's presentation titled "Benchmarking, round 2: I/O Performance", in which he tested file system performance on Linux, Windows, OpenSolaris, NetBSD, FreeBSD, and OpenBSD in order to better understand the scalability of different operating systems and IP stack throughput. Based on von Leitner's benchmarking methodology Linux has the fastest file system - reiser4.

    The testing theme continued with Poornima Bangalore, whose presentation was on the topic of "Best Practices in Linux Kernel Testing." Her talk detailed many of the key differences between traditional and open source testing. She pointed out that mainline kernel testing is more challenging than testing many other open source projects because of the rapid development and the different sub trees in the kernel: the stable kernels are released every 6 weeks or so, release candidate (-rc) kernels are available every week, and experimental (-mm) kernels are available every few days. Poornima shared best practices regarding kernel configuration, hardware configuration, test automation, test coverage, and first failure data capture.

    Heinz Mauelshagen gave a talk on device-mapper architecture features and the related target feature set. In the talk "Linux as a Hypervisor," Jeff Dike discussed the evolution of the hypervisor support in the Linux kernel and how capabilities such as ptrace, AIO and O_DIRECT make a difference to virtual machines. He also talked about the implications of FUSE (filesystems in userspace) and the manageability benefits of exporting a UML filesystem to the host. Lars Marowsky-Bree's presentation on Heartbeat 2 and Xen explored Heartbeat's ability to manage Xen guests. He expanded on Heartbeat's architecture and its integration with Xen to enable resource reallocation, globally ordered recovery actions, and data center automation policies using the Cluster Resource Manager (CRM).

    Mattias Rechenburg's presentation on "Using Enterprise Data Centers with OpenQRM" showcased the state of OpenQRM an open source project to achieve high-availability, scalability, and deployment, service and server virtualization on a variety of operation system. In spite of OpenQRM's pluggable architecture, the audience focused on the fact that it depends on a binary module which requires support from Qlusters. The general sentiment from the audience was they were not interested if they couldn't get support from Red Hat, IBM, Hewlett-Packard etc.

    In "Real-Time Approaches to Linux," Ted Ts'o shared his perspective on enterprise real-time computing and how it differs from so-called traditional real-time computing. He emphasized the changing requirements in enterprise software and how high throughput is not enough because customers increasingly also require latency guarantees, especially in particular military applications and trading systems. It was interesting to hear about the benefits and tradeoffs of different approaches to enterprise real-time including RTAI and Ingo Molnar's CONFIG_PREEMPT_RT.

    Ted suggested that guidelines outlined by his colleague Paul McKenney can be used to evaluate the different approaches to enterprise real-time. This includes quality of service, the amount of code inspection required when a new feature is added, the API provided to applications, the relative complexity, fault isolation, and supported hardware and software configurations.

    Although IBM presently has only one customer that plans to deploy enterprise real-time computing, the ability to support large SMP systems, TCP/IP, commercially available middleware, and databases makes it an area to watch in the future. Ted also elaborated on the features of IBM's real-time JVM/SDK (aka IBM Websphere Real-Time v1.0) such as RTSJ (Real-time specification for Java), the Metronome real-time garbage collector, and AOT (Ahead of Time Compilation). The talk emphasized that there are many new applications for real-time operating systems, and in particular enterprise real-time Linux.

    Maddog provided the final keynote on having fun with open source in his own inimitable way.
