Server roles determine what EmpowerID jobs (back-end processes) and Web services are enabled on a particular server. EmpowerID categorizes server roles in the following way:

All-in-One Server — The server role runs all front-end Web services and back-end processes. This role is designed to be used if you have a small environment with only one EmpowerID server.
Application Server — This server role runs all back-end processes, known as Jobs in EmpowerID. By default it does not run any Web services.
Default — This server role has no Jobs or Web services associated with it. When you install EmpowerID on a server, EmpowerID assigns this role to the server. This is to ensure that no Jobs or Web services run on a server not designated for those Jobs or Web services. Change this to the appropriate role for each EmpowerID server for that server to function as intended.
Web Front-End — This server role runs all Web services. By default it does not run any back-end processes.
