Installing vCenter Server with an embedded Platform Services Controller has the following advantages:
n
The connection between vCenter Server and the Platform Services Controller is not over the network,
and vCenter Server is not prone to outages caused by connectivity and name resolution issues
between vCenter Server and the Platform Services Controller.
n
If you install vCenter Server on Windows virtual machines or physical servers, you need fewer
Windows licenses.
n
You manage fewer virtual machines or physical servers.
Installing vCenter Server with an embedded Platform Services Controller has the following
disadvantages:
n
There is a Platform Services Controller for each product which might be more than required and
which consumes more resources.
n
The model is suitable only for small-scale environments.
You can configure the vCenter Server Appliance with an embedded Platform Services Controller in
vCenter High Availability configuration. For information, see vSphere Availability.
Note After you deploy or install vCenter Server with an embedded Platform Services Controller, you can
reconfigure the deployment type and switch to vCenter Server with an external
Platform Services Controller.
See Reconfigure a Standalone vCenter Server with an Embedded Platform Services Controller to a
vCenter Server with an External Platform Services Controller.
Platform Services Controller and vCenter Server with an External
Platform Services Controller
When you deploy or install a Platform Services Controller instance, you can create a vCenter Single Sign-
On domain or join an existing vCenter Single Sign-On domain. Joined Platform Services Controller
instances replicate their infrastructure data, such as authentication and licensing information, and can
span multiple vCenter Single Sign-On sites. For information, see Understanding vSphere Domains,
Domain Names, and Sites.
For information about managing the Platform Services Controller services, see Platform Services
Controller Administration.
You can register multiple vCenter Server instances with one common external
Platform Services Controller instance. The vCenter Server instances assume the vCenter Single Sign-On
site of the Platform Services Controller instance with which they are registered. All vCenter Server
instances that are registered with one common or different joined Platform Services Controller instances
are connected in Enhanced Linked Mode.
See Enhanced Linked Mode Overview.
