How To: Set up HA and Clustering in Titan

Question

How can I configure High Availability (HA) and clustering in Titan?

Reasoning

Titan supports HA and clustering by allowing multiple nodes to share configuration, user accounts, and session state. This ensures service continuity and load balancing between nodes. The setup typically involves shared storage and database.
