WHY VIRTUAL NETWORKS?

Businesses want the promise of dynamic, on-demand cloud based IT• Problem: Network and VM layers are too intertwined

• Provisioning of networks and network services cumbersome and slow• VM and network configurations must be coordinated – shared IP address domains• Changes to shared network services have unintended consequences

• Solution: Fully virtualized data center (VDC)• Completely separate VM and network configuration – isolated IP address domains• Create virtual overlay networks for each virtual data center• Virtualize all network services within a VDC

Visibility Black Hole• Overlay network traffic is now UDP-tunneled• Virtualization layer controls all tunnel and overlay

network setup/tear down• Impossible to isolate overlay traffic from physical

network• Different overlay networks can have overlapping
