High availability provides redundancy and stability for your multi-node Orchestrator deployment through failure resistance as multiple Orchestrator and High Availability Add-on (HAA) nodes are available - when one fails, the others pick up the load. Horizontal scalability is also available as you can add another node whenever your Robot needs grow.
Please note that this model is more resource intensive compared to a simple multi-node Orchestrator deployment, requiring at least 3 HAA nodes and the attendant Hardware and Software Requirements.
The diagram below displays a simple high availability deployment with two Orchestrator nodes and three HAA nodes:
This model can be easily scaled to suit any needs, including Active/Passive and Active/Active disaster recovery deployments for geo-redundancy.
