Editor's Notes
- #3 Thanks for coming to this session nearly at the very end of the conference!
- #4 Frank Nimphius: Glaubt alles, kauft nichts. ----- Meeting Notes (11/19/15 13:44) ----- Normally the German takes longer than the English, but not in this case.
- #5 Do spend a little time on this. You have to remind people of your experience so your story is more credible. ----- Meeting Notes (11/19/15 13:44) ----- Even though I am speaking to you here about WLS the product, my real job is to work on the specification and implementation of two parts of WLS: JSF and Servlet.
- #6 ----- Meeting Notes (11/19/15 13:44) ----- There are 18 other tracks you could have chose, plus the exhibition and the unconference, and you have chosen this one. So as a little thanks I have...
- #7 ----- Meeting Notes (11/19/15 13:44) ----- A little gewinnspiel in the theme of the 20th anniversary of Java.
- #8 ----- Meeting Notes (11/19/15 13:44) ----- This Java Factory Direct Mouse Pad will go to the person whose question at the end I like the best.
- #9 ----- Meeting Notes (11/19/15 13:44) ----- Now for the opinion piece.
- #10 ----- Meeting Notes (11/19/15 13:44) ----- There's this meme out there, fueled in part my my old pal Eberhard Wolff, ex of the Spring company. Give it a look. This reminds me of the popularity of "Tech Radars." Here is a tech radar on Tech Radars. I'm a little skeptical of tech radars.
- #11 ----- Meeting Notes (11/19/15 13:44) ----- Puppies, on the other hand, are fine.
- #12 Let’s recap the original vision for app servers. An App server is like a suburb, each house is like an app. App servers provide shared services to all the apps, such as
- #13 message queues
- #14 directory services
- #15 metering and logging
- #16 persistence
- #17 Provide sufficient isolation to all the apps
- #18 pause here. This isolation is one of the things that stays current in everything we are doing now in WLS and in the cloud as well.
- #19 Another part of the meme is about portability. This was also held up as part of the value proposition of app servers. The original vision for portability looked something like this. You could avoid vendor lock-in and let market forces work for you instead of against you: competition among vendors on price, performance, etc.
- #20 But some things are portable in name only. Look at this thing. Technically, it’s a mobile home, but it was not really designed to be mobile.
- #21 This has lead some to conclude portability is a broken down and unrealized dream.
- #22 Another frequent punching bag is the very concept of dependency injection.
- #23 Some correctly point out that this is quite similar to plain old fashioned argument passing, but I think it is fundamentally different because DI acknowledges the need to easily run code in a variety of different environments without having to change that code.
- #24 Another thing that is fueling this meme is the radically transparent and fine-grained pricing model of cloud solutions. Pay as you go: pay for only what you use. If you are paying cash for every bit of compute resource, you darn well better use those resources efficiently!
- #25 So I have been seeing a trend in the last few years, which seems to be in response to these forces…
- #26 You take what used to be your WAR or EAR and package it as an executable, such as an executable JAR *CLICK*. Package it into a Docker image. *CLICK* And deploy that image or images to the cloud. ----- Meeting Notes (11/19/15 13:49) ----- Pause here.
- #28 * Standards are the on-ramp to the cloud.
- #29 Look, if you thought app servers were sticky, clouds are even stickier. If you do your cloud based apps using standards, then you have a good shot at cloud portability. With 12.2.1, if you stick to standard APIs you have a good shot at cloud portability.
- #30 * WLS gives you the ability to run your workloads on-premise or on cloud. *CLICK* *CLICK*
- #31 * Sure, dependency injection can be misused, but the Java EE specs have been refining the idea for years and it's very capable now.
- #32 * Of course the Spring guy is going to decry portability, since they are the definition of non-portable. Customers do in fact like choice, but your mileage may vary.
- #33 * Cloud resource consumption argument: modular app servers mitigate this concern. We are aware of this and are working to make the whole stack less resource intensive.
- #34 To tie it up in this section, if you already have bought into app servers, this talk is going to show how we are extending the return on your investment
- #35 ----- Meeting Notes (11/19/15 13:51) ----- My last opinion statement.
- #38 This is where I live. This is where your developers live. This is the stickiest part, therefore the best to stick to standards.
- #39 But around the Java EE Spec features, and in fact most of the enterprise value add and product differentiation, is in what sits around those specifications.
- #40 Incidentally, this ties nicely in with Dev…
- #41 and Ops.
- #42 Lets get into some ops. Big investment in creating a shareable platform. Following model of the database, but with features that fit middleware. Pluggable partitions – enable you to encapsulate your application and the essential pieces of the environment it needs to run in, and then plug into a shared application server platform. Container like in portability; ultra light weight – only encapsulate what you need. Not the whole app server or the operating system. Consolidation: run many of these pluggable microcontainers in a shared platform. Move the virtualization bar to within the app server Isolation: to really be able to share a platform, need enough isolation so that each pluggable partition can be managed independently and will not affect each other at runtime. We have some secret ingredients that make this possible.
- #43 ----- Meeting Notes (11/19/15 13:58) ----- Let me introduce this term "Microcontainer". It's really a partition.
- #44 Start with the central platform – WebLogic running with two partitions A domain partition is an administrative portion of a domain that can be managed independently and can share the runtime capacity in a domain – the managed servers and clusters, AKA JVMs. Each domain partition has a Virtual Target, applications, and required resources (click) From the Web tier (Traffic Director or plug-ins) traffic is routed to the address defined by the Virtual Target. Once a request enters into a partition, it stays in that partition. Each partition has its own JNDI tree, so any use of resources is within the partition. That also means data segregation. For JMS, each JMS server has its own set of queues and its own persistence. (click) And each partition can have its own datasources that connect to dedicated PDBs. (PDBs are not required, but they are a natural fit) (click) And, of course, we have Coherence integration. Applications can use a dedicated Service in Coherence, or they can use a shared Service, depending on application needs. OLD: No (minimal) code change to the application – WebLogic manages the tenant identification/isolation At deployment, apps and resources in the template are deployed/replicated for each partition (tenant) specified JNDI isolation and scoping for each partition Runtime traffic is isolated end to end: The user accesses the application via the virtual host – http://baylandurgentcare.com:7011 Separate application instances have their own JNDI tree, resources Work Manager per partition to manage threads Data is segregated with PDBs WebLogic infrastructure is shared among tenants
- #45 We’re seeing an evolution in application management - combination of DevOps and a movement to break monolithic applications into smaller services ----- Meeting Notes (11/19/15 13:58) ----- Developer desktop On Premise Cloud
- #46 This is the secret ingredient, but it is really not secret. In fact, the innovations we made in the JVM are available and production usable to anything running on the JVM, not just WebLogic.
- #53 ----- Meeting Notes (11/19/15 13:58) ----- Show me the money!

- #56 Big investment in creating a shareable platform. Following model of the database, but with features that fit middleware. Pluggable partitions – enable you to encapsulate your application and the essential pieces of the environment it needs to run in, and then plug into a shared application server platform. Container like in portability; ultra light weight – only encapsulate what you need. Not the whole app server or the operating system. Consolidation: run many of these pluggable microcontainers in a shared platform. Move the virtualization bar to within the app server Isolation: to really be able to share a platform, need enough isolation so that each pluggable partition can be managed idependently and will not affect each other at runtime.
- #59 ----- Meeting Notes (11/19/15 13:25) ----- We took a look at how people were already doing continuous availability, using a collection of features from all over the product, and codified those best practices into these single features.
- #60 ----- Meeting Notes (11/19/15 13:26) ----- These are some of the configurations that are well supported with 12.2.1.
- #61 On the left, we see a diagram showing how you declare the patch to the system and the system takes care to always meet availability requitements, while rolling the patch out to all the parts of the system. Interestingly, this goes directly against the “disposable infrastructure” meme. However, I don’t know if that meme is really practical for very many enterprises. We’ve made persistent caching in coherence recoverable.
- #62 This is a simple diagram, but it says a lot. This means the entire configuration surface area of WLS is exposed three ways! Console or Fusion Middleware Control WLST at the command line REST access
- #63 Now we come to docker. We believe at Oracle that people want to easily run their workloads either on-premise, or on the cloud, depending on business or legal requirements.
- #64 This table you can read later, but the point is that we have been certifying WLS on Docker since 12.1.3.
- #65 ----- Meeting Notes (11/19/15 13:58) ----- Here is a look at the FROM clauses you would have in your Dockerfiles.
- #66 Main point: Cloud Application Foundation is the innovator’s complete and integrated modern cloud application infrastructure Built using best of breed components (WLS, Coherence, Tuxedo, more) #1 in productivity for standard and next-generation technologies, including Java, HTML5 and mobility 40% of the market-leading products are part of Cloud App Foundation Optimized to provide high availability and performance, integration tailored to Oracle Engineered Systems
- #68 If we can serialize it, be can store it! Combined with Persistence & Federation, data and lambdas can exist on disk and be shared between data-centers, devices or clouds.
