Starting with vCloud Director 9.7, you can access a dedicated vCenter Server environment from vCloud Director. vCloud Director can act as an HTTP proxy server and provide access to components from the underlying vSphere environment.
In vCloud Director, a Software-Defined Data Center (SDDC) encapsulates an entire dedicated vCenter Server environment. A dedicated vCenter Server instance can include one or more proxies that provide access to different components from the underlying environment.
The system administrator can publish one or more dedicated vCenter Server instances to your organization. You can use the containing proxies to access the UI or API of the proxied components.
