You may have seen Joey Logano speed to his first Daytona 500 win this week. Keeping your network in racing shape takes a similar level of patience, stamina, and quick reflexes.
Using VMware NSX network virtualization means that you can unlock the full potential of a Software-Defined Data Center, to create and run entire networks on top of existing network hardware, resulting in faster deployment of workloads, as well as greater agility in the face of increasingly dynamic data centers. Watch this overview to learn how VMware NSX reduces the time to provision multi-tier networking and security services from weeks to seconds to win your race.
This one-hour overview of VMware NSX outlines how you can bring virtualization to your existing network, transforming both its operations and economics. You’ll learn how several of the largest service providers, global financial, and enterprise data centers in the world are using NSX to reduce costs and provisioning times to improve agility and establish a new model of network security.

How many times have you received exact specifications of the traffic the e-commerce platform you have to deploy will generate? How do you buy a load balancer (application delivery controller in marketese) to support that (somewhat unknown) amount of traffic? In most cases, you buy a box that’s several times too big for the traffic the site is receiving most of the time, and still crashes under peak load.
