The WebSphere CloudBurst Appliance can bring speed and agility to test organizations by drastically increasing the pace and ease with which users interact with WebSphere Application Server environments. I recently got a chance to catch up with IBM's Robbie Minshall. Robbie is a WebSphere Test Architect, and he is responsible for a team of testers that harness a lab of over 2,000 physical machines to put our WebSphere Application Server product through some pretty rigorous testing. Toward the beginning of 2009 Robbie’s team started to leverage the WebSphere CloudBurst Appliance in order to create the WebSphere Application Server environments needed for their testing. Robbie, can you tell us a little bit about what the WebSphere Application Server test efforts entail? In WebSphere Application Server development and test we have two primary scenarios. The first is maki... (more)

Adopting Virtualization is Not Without Friction

This much is clear, advanced virtualization techniques are here. Some time ago, we moved beyond base operating system virtualization, towards virtualization approaches that render more functionally complete systems. From single virtual images that contain entire software stacks (i.e. LAMP, JEE servers, content management systems, etc.), to virtual appliances built to satisfy particular workloads, the functional encapsulation provided by various virtualization techniques continues to expand. On the surface, this is an obvious benefit to end-users, but that does not mean it comes ... (more)

Cloud Computing - More than Elasticity

Quite honestly, I am a little fascinated at the preponderance of focus the industry sometimes puts on the cloud attribute of elasticity. Sure, it is important, and in fact, a necessary attribute to truly consider something a cloud. It also makes for cool reading in case studies where companies have successfully harnessed elasticity in the cloud to reap business value. However, in my experience with enterprise users, many would benefit from a couple of less sexy, but equally important attributes of cloud: standardization and automation. When I am out talking with middleware appli... (more)

What's in a Cloud Appliance?

The recently announced IBM WebSphere CloudBurst Appliance is poised to make a big splash in the cloud computing market. Its ability to create, deploy, and administer private WebSphere cloud environments gives customers the ability to create and manage a services oriented cloud. To provide a more in-depth look at what the appliance delivers, I’d like to take a short look at the creation, deployment, and administration capabilities to understand what each one means to the user. To get started, in order to leverage WebSphere environments in a private cloud, you need to construct Web... (more)

Bringing Cloud Computing to SOA

There’s no shortage of opinions on how cloud computing and SOA are related. Just plug the phrase into your favorite search engine and you’ll have a day’s worth of reading. What you are likely to find are articles discussing how SOA led to cloud computing, how a good SOA is a prerequisite to leverage cloud computing, or how to leverage cloud computing in your SOA. I’ve spent quite a bit of time reading these types of articles and listening to experts talk about SOA and cloud computing, and that got me to thinking. How can companies bring the cloud experience to their SOA? In orde... (more)
