3.1. Red Hat High Availability Add-On Resource Overview
A cluster resource is an instance of program, data, or application to be managed by the cluster service. These resources are abstracted by agents that provide a standard interface for managing the resource in a cluster environment. This standardization is based on industry approved frameworks and classes, which makes managing the availability of various cluster resources transparent to the cluster service itself.
