Many organizations that have realized the benefits of server virtualization are ready to move to network virtualization. By combining hardware and software resources and functionality into a single, software-based administrative entity, these organizations can reap the benefits of greater data center agility.
But network virtualization presents new challenges. The network is not a fixed platform like a server; it is a dynamic, fluid, multivendor environment that wasn’t built with network virtualization in mind. To complicate matters, very few data centers will be 100 percent virtualized; many workloads will run only in physical environments. Thankfully, these challenges are not insurmountable. With a bit of planning—and the following best practices—organizations can overcome these challenges with a simple, open and smart approach.
