During the initial installation, a single appliance is installed, which is the Hybrid Cloud Extension. It will install one or more of the following appliances as required by your use.
- Hybrid Interconnect Appliance: This gateway provides a secure hybrid interconnect to the remote site with intelligent routing to avoid networking “middle mile” problems.
- WAN Optimization Appliance: This appliance improves performance by utilizing WAN optimization techniques such as data de-duplication and line conditioning.
- Network Extension Service Appliance: This appliance extends L2 networks to the remote site. This enables moving VMs to the cloud without IP and MAC address changes. This service does not require the presence of NSX for vSphere.
