The following diagram illustrates the architecture behind Talend Identity and Access Management when set up in cluster mode.
This architecture is composed of several functional blocks:
- A client connects to any running instance of a Talend application.
- A Load Balancer accepts incoming traffic from Talend application instances and routes requests to any running instance of Talend Identity and Access Management in the cluster.
- Talend Identity and Access Management securely authenticate users, authorize users to access Talend applications and save users' session data in MongoDB.
- MongoDB stores and loads users' session data. You can configure MongoDB in cluster mode. For more information, see MongoDB documentation.
Note: The embedded H2 database is not recommended for production environments. To check which databases are recommended for production environments, see Compatible databases. To change the Talend Identity and Access Management database, see Changing Talend Identity and Access Management database. Talend recommends that all nodes in the cluster share the same OIDC and IDP database.
