Multiple Cell Architecture
Each Cell will have a different role automatically assigned.
Multiple cells provide load-balancing.
Each vCloud Director cell is automatically assigned a role. When communications requests come into the load balancer requests fall into one of four major categories:
• User Interface (UI). This is the main Web console that administrators and operators use to manage vCloud Director.
• API. The API consists of commands that can be issued to vCloud Director from other systems and scripts through the API. Some commands and functions can only be issued though the API.
• Virtual Machine Remote Console (VMRC). This is the pop-out console that an operator can open on any virtual machine running in vCloud Director.
• Image Transfer. This is the system that allows files and images like .ISO files to be uploaded into vCloud Director.
A master cell (selected by vCloud Director) coordinates the role assignment to VCD cells.
