Yesterday, I had the opportunity to present WebSphere CloudBurst during the IBM Cloud computing for developers virtual event. I provided a brief overview of the appliance along with a demonstration, and then tackled some questions from the 150+ attendees in the audience.
All of the questions were good ones, and I wish I had time to address them all during the session (I will be answering all questions and posting them online soon). However, one of the questions stood out to me because of its relevance to how IBM uses WebSphere CloudBurst in their own labs. Paraphrasing, the question was "Can you share hardware resources (hypervisor hosts) between WebSphere CloudBurst and other components in your data center?"
Very good question. The answer is, of course, yes you can. I don't want to sugarcoat it because it does require thought and planning. Ideally, when WebSphere CloudBurst is using a hypervisor host, the appliance is the only thing acting on that host. However, when WebSphere CloudBurst is not using that host, then you can absolutely repurpose it for use by other components in your data center.
Our WebSphere Test Organization uses WebSphere CloudBurst to aid in their testing of our WebSphere middleware products. The capability to provision hypervisor hosts in and out of the WebSphere CloudBurst cloud is of critical importance to them. Like many organizations, they are resource constrained and must get the most out of their IT investment. They use the Tivoli Provisioning Manager to provision VMware ESX hosts for use by WebSphere CloudBurst, and then they use the WebSphere CloudBurst CLI to define those hypervisors to the appliance and do verification testing of the new resource. This allows them to easily expand and contract the amount of shared infrastructure utilized by WebSphere CloudBurst at any one time, and it means components do not have to statically lock down resources. I have a lot more information to come about our WebSphere Test Organization and their use of WebSphere CloudBurst, but I thought I would give everyone a peek at the kinds of things they do everyday with the appliance.
If you are interested in what I presented yesterday to the attendees of IBM's Cloud computing for developers event, you can check out their developerWorks Group page. In the Activities section, you will find the charts, demonstration, and a playback if you prefer to listen to the session. As always, I appreciate your feedback and questions.
