What advantages does a customer get with virtual networking?
The primary benefit is the time it takes for you to do anything you want to do on the networking side. Virtual networking drastically reduces the provisioning time of network resources. In an age where IT lives and dies by the time it takes to get things done, that's an advantage. The second is the operational overhead; easier deployment of resources reduces the chances of mistakes. And third, there is a capital element here; now customers have a choice of what networking gear they want to deploy, which is something many customers don't have today.
What about the higher-level networking stuff -- the ELBs, firewalls, etc.?
One area we really hope to differentiate on is VMware's long history of being a partner-focused company. We're hoping any existing Layer 4-7 device would be available in this new world. We think we're adding a lot of value to the networking side, and we're hoping to integrate existing network components in with that. VMware will have some load balancers and VM provisioning, but we'll also work with partners to offer choices to customers.
