Temporal as a Service (TaaS) is the durable workflow engine that powers Maestro on Automation Suite. TaaS is built on [Temporal](https://temporal.io/), an open-source platform designed for reliable, long-running workflow execution.

TaaS is automatically enabled when Maestro is installed on Automation Suite. No additional licensing is required.

## How TaaS works

TaaS handles workflow coordination for Maestro process execution. When a Maestro process runs, TaaS tracks workflow state, manages retries, and persists execution history — ensuring processes resume correctly after failures or restarts.

TaaS does not execute business logic directly. Maestro's worker services connect to TaaS and perform the actual work of each workflow.

## Requirements

For TaaS infrastructure requirements, see the Automation Suite installation guide for your deployment:

- [EKS/AKS](https://docs.uipath.com/automation-suite/automation-suite/2.2510/installation-guide-eks-aks/meeting-product-specific-prerequisites)
- [OpenShift](https://docs.uipath.com/automation-suite/automation-suite/2.2510/installation-guide-openshift/meeting-product-specific-prerequisites)

## Monitoring

TaaS exposes Prometheus metrics from each server pod. For information on key metrics and how to access the Temporal web UI, see [Using the monitoring stack](https://docs.uipath.com/automation-suite/automation-suite/2.2510/installation-guide-eks-aks/using-the-monitoring-stack#monitoring-temporal-as-a-service-taas).
