IBM Session at Cloud Expo From a constrained viewpoint, the WebSphere CloudBurst Appliance serves as a virtualization management solution for WebSphere application environments. In that light, I cannot tell you how many times customers ask me to delineate WebSphere CloudBurst from the other virtualization management solutions that are either out on the market or currently used in their business. I love to hear this request for two reasons: 1)      It signals that many enterprises already practice or are thinking about virtualization in the application environment space. 2)      I have a good answer! To understand the main delineation between WebSphere CloudBurst and other virtualization management solutions, it is probably helpful to understand what the appliance does! Put simply and shortly, the appliance enables you to create, deploy, and manage virtualized WebSp... (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)

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)

Back to Square One

I grew up playing quite a few different sports, both team and individual. For me, there was little else that I would rather have done than compete on the field, court, diamond, or course. I loved sport, and I loved to compete (still do as a matter of fact), so it was a great fit. Partially motivated by getting me to focus on something other than annoying the crap out of my little brother, my parents strongly encouraged my involvement in sports of all kind. For that, I will always be grateful. Not because I parlayed my athletic experience into a seven figure contract, flashy cars,... (more)

What Is an Application?

What is an application? Well, like many things the answer varies widely based on who you ask. Consider the case of an online ticket booking application. If you ask the users of the application what the application is, then it's a web page or a series of web pages. If you ask the application development team, they will say it's a collection of source code, configuration files, static content, etc. The infrastructure team will tell you the application is the application server, web server, and operating system. If you go further and ask the hardware folks what they think, they will... (more)
