Overview of Gateways and Networks 1
vCloud Air networking replicates traditional network technologies and design. Networking in vCloud Air is
based on the software-defined networking (SDN) technologies used by VMware products, including
VMware vSphere, VXLAN, vCloud Networking and Security, and vCloud Director.

Network Virtualization in vCloud Air
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.
