The N1 Grid Service Provisioning System is Sun Microsystems product for service (software) Distribution in the N1 environment. It consists of four components:
The Master Server which is the core component for the service distribution.
The client component is called Remote Agent. It has to run on every target host.
A proxy component called Local Distributor. The Local Distributor is used to minimize data transfer between datacenters.
A command line interface which can be installed on every host.
The Master Server is built upon Apache Tomcat and the PostgreSql Database. All other components are pure Java.
The Sun Cluster HA for N1 Service Provisioning System data service provides mechanisms for orderly startup and shutdown, fault monitoring, and automatic failover of the Master Server, the Remote Agent and the Local Distributor.
