Why We Need Network Abstraction

The move to highly virtualized data centers and cloud models is straining the network. While traditional data center networks were not designed to support the dynamic nature of today’s workloads, the fact is, the emergence of highly virtualized environments is merely exposing issues that have always existed within network constructs. VLANs, VRFs, subnets, routing, security, etc. have been stretched well beyond their original intent. The way these constructs are currently used limits scale, application expansion, contraction and mobility.  To read the full article visit: http://www.networkcomputing.com/next-gen-network-tech-center/why-we-need-network-abstraction/240142588
