Starting with vCloud Director 9.7, you can access a 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 vCenter Server environment. An SDDC can include one or more SDDC proxies that provide access to different components from the underlying environment. The system administrator can publish one or more SDDCs to your organization. You can use the containing SDDC proxies to access the UI or API of the proxied components.
