After deploying the vRealize Automation proxy agents, set up anti-affinity rules.

A VM-Host anti-affinity (or affinity) rule specifies a relationship between a group of virtual machines and a group of hosts. Anti-affinity rules force the specified virtual machines to remain apart during failover actions, and are a requirement for high availability.
