Network Virtualization and Cloud Computing
As businesses move more toward cloud computing, one important factor for success is adopting multi-tenant software-defined networking (SDN) solutions in data centers. Hyper-V Network Virtualization (HNV) is a key enabler for a multi-tenant SDN solution and is essential for implementing a hybrid cloud environment where tenants can bring not only their own IPs, but their entire network topology since the virtualized networks are abstracted from the underlying fabric network. Network virtualization in general and Hyper-V Network Virtualization in particular are relatively new concepts. Unlike server virtualization, which is a mature, widely-understood technology, network virtualization still lacks this kind of broad familiarity. This brief book identifies some key usage and deployment scenarios for cloud computing to provide some deep technical background on the Microsoft SDN solution, enabling IT professionals to quickly learn the internals of HNV, how it works from end to end, and wh ...
