patterns to reduce bandwidth usage and insures best usage of available network capacity to expedite data transfer to
and from vCloud Air.
• Virtual machine migration relies on the combination of Cloud Gateway and WAN Optimization appliance to achieve
unparalleled mobility between vSphere on-premises and vCloud Air
• L2 extension benefits from WAN optimization when the data path is routed through the Cloud Gateway (Hybrid
Transport option in the workflow)
Choosing a Deployment Architecture
The most common use case is to install the Hybrid Cloud Manager and all three types of Software-Defined WAN
appliances, as shown in Figure 1 on page 7. Table 2 summarizes the possible use cases, and what the minimal installation
entails.
A single path architecture uses the Cloud Gateway for all communication.

. The primary advantage of the Premium option is speed. Because there is a 1:1
relationship between a vCenter and a vCloud Air vDC, the number of connections only matters if you are using Linked Mode on premises.

WAN enhances security and speed for workloads passing through the Cloud Gateway.

Networking bandwidth is limited by your purchased hybrid networking option or your native bandwidth, whichever is smaller.
