Is JVM clustering required for PEGA AES setup

We don’t have JVMs clustering in our current environment. Could you please suggest if it's mandatory to have JVM cluster before HA setup.

JVM clustering is not required but it is recommended.

You can run a one node AES system, where that node processes messages and runs agents. 

You can run a two node AES system  without load balancing - one node handles message; one node runs agents and search (a batch node)

We run the PDC service - sort of a multi-tenant AES - with three node scalable clusters. Two nodes always available for messages / browsers (we are experimenting with auto-scaling for additional capacity during peak) and one node for batch.
