This document describes the plugin cluster service architecture and is intended for developers of cluster services to plug third party cluster services in to OpenAIS.

OpenAIS is a completely modular proces where each cluster functonal service plugs in at run time into a “cluster kernel” calld the OpenAIS executive. This process is responsible for all cluster operation in the system. The intent of this system is to allow any party to develop cluster applications without focusing on the complex and time consuming development of protocols and core infrastructure.
