Applications, users, specific services, and even entire business segments are all tied to network capabilities and delivery architectures. And with all the growth around cloud, virtualization, and the digital workspace, the network layer has become even more imporant .
Most of all, we’re seeing more intelligence and integration taking place at the network layer. The biggest evolution in networking includes integration with other services, the integration of cloud, and network virtualization. Let’s pause there and take a brief look at that last concept.

There are big business initiatives supporting the technology. Very recently, IDC said that the worldwide SDN market, comprising physical network infrastructure, virtualization/control software, SDN applications (including network and security services), and professional services, will have a compound annual growth rate of 53.9% from 2014 to 2020 and will be worth nearly $12.5 billion in 2020.
As IDC points out, although SDN initially found favor in hyperscale data centers or large-scale cloud service providers, it is winning adoption in a growing number of enterprise data centers across a broad range of vertical markets, especially for public and private cloud rollouts.
