The single-node deployment option is recommended for evaluation and demo scenarios because it is simpler and faster to set up and requires less resources. It involves installing the Automation Suite on a single server node, which hosts both the cluster management services and the UiPath products and shared components. This option is not suitable for production use, as it does not provide high availability, scalability, or fault tolerance.
It also does not support special workloads that require GPU capabilities, such as Task Mining analysis and Document Understanding pipelines. References:
