Interest in cloud computing has witnessed a significant surge in the past few years. The basic tenet of this concept entails the reduction of in-house data centers and the delegation of a portion or all of the Information Technology infrastructure capability to a third party. This holds the promise of driving down cost while fostering innovation and promoting agility. Three typical kinds of cloud services are: Processing Clouds that provide scalable and mostly affordable computing resources that run enterprise programs, Storage Clouds that offer an alternative to local file systems, and Application Clouds that allow a thin client to interact with services that are completely hosted on an external infrastructure.
