Evolution of Virtual Switching
The effects of virtualization today are felt across the IT spectrum, from the physical layer in a data center, up to the application layer. Particularly, server virtualization has blurred the traditional demarcations between networks, security, and computer technologies and their respective administration responsibilities. Furthermore, server virtualization has made the enforcement of security policies, rules, and networking fuzzy and hard to pinpoint because a server workload or application can now run from anywhere, any server, and any port. It is very fluid, and that poses a significant challenge in the data center today.
