Choosing an architecture

Sections

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. All PE installations begin with the standard configuration, and scale up by adding additional components as needed.

Configuration Description Node limit
Standard 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
Large installation Similar to a standard installation, plus one or more compilers and a load balancer which help distribute the agent catalog compilation workload. 4,000–20,000
Extra-large installation Similar to a large installation, plus a separate node which hosts the PE-PostgreSQL instance. More than 20,000
Tip: You can add disaster recovery to an installation with or without compilers by configuring a replica of your master. Disaster recovery isn't supported with standalone PE-PostgreSQL.
