CIOs are looking for ways to achieve greater IT efficiencies and agility to meet their requirements for an improved user experience and lower costs. Cloud computing represents a new way of meeting these goals by delivering services on a dynamic and shared IT infrastructure. Previously, applications were linked to hardware that was specifically designated for compute and storage. With cloud computing, the functionality of these same software and hardware products is delivered in a more scalable fashion as services over a network. CIOs are looking to apply the lessons of the cloud to their own IT departments to optimize results. However, they are limited because, as application architectures, server virtualization, and storage technology have evolved over time, innovation in the network has not kept pace. Because networks are the foundation of a cloud-ready data center, businesses need a new network to unleash the promise of the cloud.
