Remote plug-ins can operate in linked mode configurations of vCenter Server as well as in single vCenter Server instances. Illustrations in this chapter show the components and communication paths for both kinds of configuration.

The following illustration shows a single vCenter Server communicating with a web browser.
Figure 1. vCenter Server and Web Browser Communicatiions
This diagram shows the various communication paths between processes running in the vCenter Server and processes running in the browser.

In a linked mode configuration, the vsphere-ui service handles delegation of requests to the linked vCenter Server instances, using the same protocols that it uses when communicating with its own services..
