Sun Cluster HA for N1 Service Provisioning System

1. The Master Server which is the core component for the service distribution.

2. The client component is called Remote Agent. It has to run on every target host.

3. A proxy component called Local Distributor. The Local Distributor is used to minimize data transfer between datacenters.

4. A command line interface which can be installed on every host.
