Cloud networking services for enterprises

As more enterprises look to leverage the cost and flexibility advantages of cloud computing, the lack of rich networking support remains a challenge. In this paper, we discuss the requirements of enterprise line-of-business applications for additional network functions in the cloud, and argue that a service-level abstraction for the network is needed. After reviewing some of the trends in cloud network architecture, we describe two ongoing research efforts to develop networking services for multi-tenant enterprise clouds, and workload-optimized modular data centers.
