| High Availability Installation | |
Orchestrator runs in active/active mode for Apache and Orchestrator services, and in active/passive mode for MySQL.
The Orchestrator HA environment can run on-premise or in the cloud.
The use case described in this guide is a dual Orchestrator instance cluster, where the Orchestrator step execution is balanced between two active nodes, providing a high-availability service with seamless automatic failover in the event that one node fails or becomes unavailable.
It is possible to have more than two nodes in an HA environment. However, these use case scenarios are not addressed in this document. Contract Aspera Professional Services if you need further information about configuring another type of environment.
