There are several configurations available for Puppet Enterprise. The configuration you use depends on the number of nodes in your environment and the resources required to serve agent catalogs.
|Monolithic installation (Recommended)||All infrastructure components are installed on the master. This installation type is the easiest to install, upgrade, and troubleshoot.||Up to 4,000|
|Monolithic installation with compile masters||Similar to a monolithic installation, plus one or more compile masters and a load balancer which help distribute the agent catalog compilation workload.||4,000–20,000|
|Monolithic installation with compile masters and standalone PE-PostgreSQL||Similar to a monolithic installation with compile masters, plus a separate node which hosts the PE-PostgreSQL instance.||More than 20,000|
Tip: You can add high availability to a monolithic installation, with or without compile masters, by configuring a replica of your master or master of masters. High availability isn't supported with standalone PE-PostgreSQL
