Master instances are special instances that run an essential set of services, including:

  • Admin-App service
  • Cluster-Coordination service
  • Synchronization service
  • Service-Deployment service

Non-master instances are called workers. Workers can run any services except for those listed previously.

Single-instance systems have one master instance while multi-instance systems have either one or three master instances.

Important: You cannot add master instances to a system after it's installed. You can, however, add any number of worker instances.
