Deployment Topologies with External
Platform Services Controller Instances and High
Availability
To ensure Platform Services Controller high availability in external deployments, you must install or
deploy at least two joined Platform Services Controller instances in your vCenter Single Sign-On domain.
When you use a third-party load balancer, you can ensure an automatic failover without downtime.

You can use a third-party load balancer per site to configure Platform Services Controller high availability
with automatic failover for this site. For information about the maximum number of
Platform Services Controller instances behind a load balancer, see the Configuration Maximums
documentation.
Important To configure Platform Services Controller high availability behind a load balancer, the
Platform Services Controller instances must be of the same operating system type. Mixed operating
systems Platform Services Controller instances behind a load balancer are unsupported.
The vCenter Server instances are connected to the load balancer. When a Platform Services Controller
instance stops responding, the load balancer automatically distributes the load among the other functional
Platform Services Controller instances without downtime.
