On-Premises Environment
When working in an on-premises environment, Identity Manager needs a specific architecture.
Overview
Identity Manager recommends the following architecture:
Most situations do not need Identity Manager so much that they need a fail-over system, i.e. installing several Identity Manager instances in order to prevent breakdowns. In most situations, a single Identity Manager instance is enough.
Server
The server should be stateless, i.e. it should store only temporary files.
Agent(s)
One or several additional agents can be needed only when using a sensitive network, for example an administration network separated from the main network.
Database
The database is a critical item, and thus should be set up with a mirror. The database mirror can have lower CPU and RAM and be on a different location.
Identity Manager recommends using an incremental backup.
