I am designing Pega nodes. I know we need to have a load balancer in front of WebUser nodes but how about non WebUser nodes? WebUser can work as active-active but can non-WebUser nodes also work as active-active, or it has to be active-standby. If it can work as active-active, I am guessing we should place a load balancer in front of them as well. Can load balancer for WebUser nodes be shared for non-WebUser nodes? Or should we have a separate load balancer for non-WebUser nodes.
