Business resilience and disaster recovery are core capabilities required of the data center IT infrastructure. The emergence of cloud computing has put a brighter spotlight on the need to ensure that a robust resilience strategy is in place down to the virtual machine. This places new and greater demands on the network in order to ensure virtual machine mobility, security and availability while still maintaining the flexibility and agility of a cloud model.
One of the main concepts of Cloud Computing is to provide automatically and dynamically almost unlimited resources for a given service in a fully virtual environment. However in order to provide those resources, the complete architecture for the cloud computing must be built with efficient tools and sturdy solution design, not only at the compute stack level but network and storage sides, in order to offer Business Continuity without any interruption.
