High Availability Architecture

In a production setting, we recommend that you use a high-availability deployment. You install two or more instances of each component, except for Oracle or PostgreSQL databases. If any server or other component becomes unavailable, a duplicate server operates in its place. This appoach minimizes the risk of service interruption.

Note: For the purposes of this document, we assume that a high-availability deployment has two instances of each component, except for the databases.

This diagram illustrates the functional architecture for a high-availability environment
