Much of the focus on cloud computing to date revolves around the ways in which cloud computing delivers significant administrative and operational benefits. After all, the more dynamic, autonomic capabilities promised by cloud could go a long way in relieving some of the burden in managing large, complex IT infrastructure operations. Sometimes lost in the cloud computing benefits discussion is how cloud computing enhances development and test groups in an enterprise.  I can think of five different ways in which cloud computing strengthens development and test groups: 1) Self-service capability: A defining characteristic of cloud computing solutions is a self-service capability that allows users to commission and decommission computing resources as appropriate. In development and test shops, this means users can directly procure the resources they need to complete th... (more)

Important Considerations to Build Cloud Computing Apps

In many cases the industry talks about cloud computing being a new and optimized approach to delivering IT services. From the point of view of application developers, cloud computing offers dynamic platforms that equip them with the capability to deliver their application in an on-demand fashion. Applications running on a cloud platform scale up and down to meet the needs of its users. So, in the face of this new delivery model for applications, should application architects and developers expect this to have an impact on application architecture and design? There are indeed con...

Cloud Computing and Virtual Images

Cloud Expo on Ulitzer A look at several different cloud computing solutions will reveal a technological enabler present in almost each one. The enabler I'm talking about is the use of virtual images. I cannot think of many, if any, cloud computing solutions that provide software elements (i.e. more than just servers, storage, memory, etc.) that do not use virtual images in some form or fashion. Of course, one of the reasons virtual images form the backbone of many cloud solutions is obvious. Virtual images provide the benefits of server virtualization. We can activate many virt... (more)

Is WebSphere CloudBurst Right for You?

IBM Session at Cloud Expo Trying to pick apart a particular IT solution to figure out if it is right for you and your business can be a daunting task. Trying to do that for solutions in emerging spaces, like cloud computing, can seem even more difficult to the point of looking almost impossible. Case in point, at most of my WebSphere CloudBurst sessions someone (usually multiple people) always asks how they can determine if this particular product is right for them. It's a good and fair question, and one that I usually answer by asking a few questions of my own. To best underst... (more)

What Does Elastic Really Mean?

Normal 0 MicrosoftInternetExplorer4 In terms of cloud computing in application environments, elasticity is perhaps one of the more alluring and potentially beneficial aspects of this new delivery model. I'm sure that to many of those responsible for the operational and administrative aspects of these application environments, the idea that applications and associated infrastructure grows and shrinks based purely on demand, without human intervention mind you, sounds close to a utopia. While I would never dispute that such capability can make life easier and your environments muc... (more)
