Hybrid Cloud Manager uses software-defined WAN Optimization.

The WAN Optimization appliance is an optional, yet highly recommended, component that performs WAN conditioning to reduce effects of latency. It also incorporates Forward Error Correction to negate packet loss scenarios, and deduplication of redundant traffic patterns. Altogether, these reduce bandwidth use and ensure the best use 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.

Layer 2 extension benefits from WAN optimization when the data path is routed through the Cloud Gateway.
