This document discusses new features in Puppet Enterprise 2016.5 that improve high availability, including eliminating single points of failure to ensure Puppet continues running. It introduces simple agent-side failover that happens at the application level for enterprise customers, promoting a replica when the primary fails. During failovers in Puppet Enterprise 2016.5, scheduled Puppet runs, catalog compilation, and reporting can still occur, but deploying new code, editing node classifier data, using the console, certificate functionality, most CLI tools and application orchestration are not possible.
