IBM CloudBurst and WebSphere CloudBurst Appliance Compared

What is a cloud computing platform? Is it simply automated provisioning systems coupled with a resource virtualization, where the workload is policy driven, and resources over committed and any resource contention handled by policy driven resolution? As it turns out technologies that provide provisioning, virtualization and policy enforcement form the building blocks of a true cloud computing platform, but not any one technology is a cloud offering in and of it self. IBM’s CloudBurst family attempts to provide a single cloud solution with an appliance form factor. This paper will... (more)

Is Cloud Computing Just Virtualization and Automation? No!!

Day and day out, we see every technology vendor attempting to position themselves in the cloud realm and struggling to find a niche in this 'cloudy' topic. I think: 1. Virtualization and Automation are the building blocks of the cloud computing platform. They alone will not solve any problems. 2.

So with growth in business either due to larger client base or new business model implies similar growth in middleware. This consistent growt... (more)

Scalable HTTP Session Management with WebSphere Extreme Scale (WXS)

HTTP session management is a function offered by Java Enterprise Edition (JEE) application servers. It allows JEE applications to store state information about a given user across many HTTP requests. The JEE specification provides an API to store and retrieve information specific to the given user. WebSphere application servers and other competing products, provide session replication functionality. This is normally done either by writing to a database or through memory-to-memory replication technology.  These approaches while extensively used today, have operational challenges ... (more)
