Network virtualization in vCloud Air provides the ability to extend your virtual machines in your private cloud to the VMware public cloud via the network.

The following VMware products and solutions work together to provide the network virtualization and functionality in vCloud Air.

vSphere is the foundation on which vCloud Air is built. On top of vSphere, Virtual eXtensible Local Area Network (VXLAN), part of VMware vCloud Networking and Security, provides the functionality necessary to implement a flexible virtual network in the data center. VXLAN—dynamic and encapsulated—provides the ability to deploy networks in vCloud Air rather than requiring complex VLAN architectures. VXLAN technology allows compute resources to be pooled across non-contiguous clusters and segmented into logical networks attached to applications. VXLAN allows for full encapsulation at Layer 2, thus providing network security. Also part of vCloud Networking and Security, the gateway virtual appliance enables networking services, such as the firewall, NAT, load balancer, and a VPN endpoint.

The vCloud Air console is the primary portal for managing gateways and networks. Additionally, you can use the vCloud Director to manage your gateways and networks at a more granular level. The vCloud Air console provides single sign-on access to vCloud Director.
