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)

WebSphere eXtreme Scale Design and Performance Considerations

Fundamentals: How does WXS solve the Scalability problem?

For example, it can refer to the capability of a system to increase total throughput under an increased load when resources (typically hardware) are added." Scalabil... (more)
