High Availability (HA) in the context of UiPath Orchestrator is a setup designed to ensure that the system remains available and operational, even in the event of hardware failures, software crashes, or other unexpected issues. HA is achieved by implementing a multi-node Orchestrator deployment, where multiple instances of Orchestrator are run in parallel. This setup provides redundancy, meaning if one node fails, the others can take over, ensuring continuous operation. The key benefit of HA is its ability to resist failures and maintain stability, which is crucial for critical enterprise operations relying on RPA.
