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.

balancer in each site.
