Cloud computing represents not a revolution but an evolution of existing enterprise computing architectures, dating back to the first instance of networked computing. The difference is that today there are vast advances in virtualization in nearly every aspect of the data center. There has also been an emergence of a dynamic understanding and need to control what, how, and when the cloud provides services to the consumers of those services. This new dynamic paradigm must be able to intercept application and data traffic, interpret the current context, and instruct the cloud infrastructure on how to most efficiently deliver the request.
