Supported use cases for single-node and multi-node installations

Why the single-node mode is only suitable for evaluation purposes, whereas the multi-node profile can be implemented in production.

Automation Suite supports two deployment modes, each targeted at specific use cases, as explained in the following table:

Deployment mode	Description
Single-node — evaluation	Supported only for evaluation and demo scenarios. Single-node evaluation profile requirements and installation
Multi-node — production, HA-enabled	The only configuration supported for production deployments. You can perform additional configuration post-deployment to have full HA capabilities. Multi-node HA-ready production profile requirements and installation

Context and considerations

Automation Suite uses a cloud native architecture based on Kubernetes. It provides all the benefits in scale, automatic resource management, and reliability that come with Kubernetes.

To offer these benefits, the Kubernetes design is based on the following fundamental aspects:

Running on an uneven number of multiple machines (3, 5, 7, etc.);
Using the quorum principle to handle independent node failures and data corruption. For a cluster of N machines, as long as there is still a number of N/2 + 1 machines that have quorum, the cluster is functional and can recover gracefully with no observed failures.

Single-node installations

By definition, single-node deployments do not benefit from the previously described characteristics and are not supported for production deployments. Failures and data loss can and will occur. In case of failure, data recovery for single-node deployments without backup is not supported.

However, since support for single-node deployments is valuable for evaluation and demo scenarios, UiPath® offers this deployment option applicable to some specific use cases.
