vCloud Connector Architecture
vCloud Connector is a virtual appliance. vCloud Connector installs in vSphere and handles all the business logic of dealing with other clouds. The vCloud Connector UI is displayed in the vSphere Web Client through a browser plug-in.
You have two considerations about where to place your vCloud Connector appliance:
The virtual appliance must be deployed to a vCenter Server system. The only user access is through the vSphere Web Client, so users of vCloud Connector must have the right to log in to this vCenter Server system.
Workload copy operations use the vCloud Connector appliance as a middleman, so network latency and bandwidth between clouds must be considered. In some cases, you might prefer to run multiple instances of vCloud Connector across multiple vCenter Server instances to avoid network latency or consuming excessive bandwidth.
