The 1.1.1 version of WebSphere CloudBurst is now available on the IBM support site, and you can read a bit about it here. I have not blogged about each and every point release of WebSphere CloudBurst here, but this particular one is significant. The 1.1.1 release adds support for IBM's z/VM hypervisor platform as a deployment target.
Quite simply this means that you can now create virtualized WebSphere application environments on the z/VM platform using WebSphere CloudBurst. This starts by first defining target hypervisors, instances of Linux Master Systems, that WebSphere CloudBurst can communicate with to setup virtual machines on z/VM. Coupled with support for the z/VM infrastructure components, there is a new version of the WebSphere Application Server Hypervisor Edition virtual image. While this new image contains the same basic components as the previous hypervisor edition images, it is packaged for the z/VM platform, and it includes a zLinux operating system.
Once you upgrade to WebSphere CloudBurst 1.1.1, you can define your z/VM infrastructure and use the new WebSphere Application Server Hypervisor Edition image to build custom patterns targeted for the z/VM platform. I put together a demonstration that provides a very brief overview of these new capabilities. As always, please reach out if you have any questions about this or any other WebSphere CloudBurst topic.
Since its introduction and initial release around one year ago, activity around WebSphere CloudBurst has been a steady buzz. New images, features, enhancements have been rolling in, and can sometimes be a little overwhelming to digest. With that in mind, I want to address a related and frequent question. What products does IBM support for use in WebSphere CloudBurst?
To answer that question, we only need to look at the IBM Hypervisor Edition images currently provided by IBM. Here's a quick matrix of those images:
For the last post in my FAQs Revisited series, I'm going to cheat a little bit. Instead of addressing one particular question, I'm going with a grab bag of a few different questions. These are questions that I get asked quite frequently, but do not demand an entire blog post explanation. Let's get on with it.
Question: Do the new software license management capabilities provided in WebSphere CloudBurst 2.0 depend on ILMT or other supporting components?
Answer: No. The license management features are completely standalone. Of course, you can still take advantage of ILMT (through easy integration in WebSphere CloudBurst I might add) to track licenses in your cloud if you so choose.
Question: Can I deploy a pattern, make changes to my virtual system, and then recapture that as an updated pattern?
Answer: You cannot do this with WebSphere CloudBurst alone, but you can use WebSphere CloudBurst in conjunction with the Rational Automation Framework for WebSphere to do just this. Check out this article (shameless plug alert!).
Question: What if I have an urgent operating system fix to apply before IBM delivers an update to the OS in the Hypervisor Edition image?
Answer: You can either manually apply the fix to the appropriate virtual machines, or you could package up the fix as a custom WebSphere CloudBurst fix, load it into the catalog, and use the appliance to automate the application of said fix.
Question: Can I change the install location for WebSphere Application Server in the virtual image?
Answer: I've just shown you all this really cool, useful, and easy to use stuff, and you worry about install locations? Seriously though, I understand the genesis of this question usually has to do with existing scripts that assume a certain install location for WebSphere Application Server. I certainly do not advocate changing those scripts, but you cannot change the install location for WebSphere Application Server in the images. There is nothing to keep you from creating a symbolic link however.
Question: Once I deploy a pattern, what do I need to do to add more processing capacity (i.e. more application server processes)?
Answer: You have a couple of options here. You can use normal WebSphere administration techniques to add more application servers to an existing node. If that will not work (perhaps a particular node is operating at max capacity), you can use the new dynamic virtual machine operations in WebSphere CloudBurst to add an entirely new node/virtual machine. If you find yourself consistently making these types of adjustments to the runtime environment based on ebb and flow of demand, you may also want to consider the Intelligent Management Pack option for WebSphere Application Server Hypervisor Edition.
I hope this FAQs Revisited series was helpful. Stay tuned for a look at some recent work I did to integrate WebSphere CloudBurst deployments with the new WebSphere DataPower XC10 appliance.
It seems like it was announcement day across IBM, and specifically in WebSphere. While the announcements were numerous and touched many different topics, I want to focus on a couple of announcements of particular interest to those of you interested in WebSphere CloudBurst and IBM Hypervisor Edition virtual images.
First, for all of our WebSphere Process Server and WebSphere Business Monitor users, there are a couple of important pieces of information in this announcement. This announcement outlines the availability of WebSphere Business Monitor Hypervisor Edition. The new image allows you to dispense WebSphere Business Monitor 7.0 environments using WebSphere CloudBurst to VMware hypervisors. In addition, the announcement outlines the expansion of the existing WebSphere Process Server Hypervisor Edition image to support the z/VM platform and the Red Hat Enterprise Linux (RHEL) operating system for VMware.
Moving beyond our BPM set of solutions, IBM also announced the availability of a WebSphere Message Broker Hypervisor Edition. This virtual image allows you to construct and deploy WebSphere Message Broker and WebSphere MQ environments using WebSphere CloudBurst. The stack includes the RHEL operating system, and it is ready to run on VMware hypervisors.
With that in mind, here's an update to the WebSphere CloudBurst supported product matrix:
* Availability subject to dates documented in referenced announcement letters
As you can see, we are continuing our effort to expand the choice you have when using WebSphere CloudBurst to create and deploy application environments to your cloud. If you are interested in using WebSphere CloudBurst for WebSphere Business Monitor, WebSphere Process Server, or WebSphere Message Broker, check out the above announcements. You will find more technical information as well as planned availability dates.
Just one last scrap of food for thought. Feedback from you, our users, is instrumental as we continue to expand software choice with WebSphere CloudBurst. Please continue to let us know your thoughts and needs!
