Understanding Scalability In understanding the scalability challenge addressed by WebSphere eXtreme Scale, let us first define and understand scalability. Wikipedia defines scalability as a "desirable property of a system, a network, or a process, which indicates its ability to either handle growing amounts of work in a graceful manner, or to be readily enlarged. 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." Scalability in a system is about the ability to do more, whether it is processing more data or handling more traffic, resulting in higher transactions Scalability poses great challenges to database and transaction systems An increase in data can expose demand constraints on back-end database servers This can be a very expensive and short term approach to ...

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)
