Multi-Node Deployment

If your deployment has grown and you need to increase capacity, expanding your Orchestrator to a multi-node installation is the next logical step. It offers both better performance and failure resistance as multiple Orchestrator nodes are available - when one fails, the other(s) can pick up the load. Horizontal scalability is also available, as it is possible to add additional nodes as your Robot needs grow further. This deployment model should not, however, be confused with High Availability, as the lone HAA node remains as a potential single point of failure.

Please note that this model is more resource intensive than a single node installation, requiring additional components such as the for Orchestrator (or other tested solution) and a network load balancer.

The diagram below depicts a simple multi-node deployment of two or more Orchestrator nodes synchronized using a single HAA node:
