5.16.0 Release Notes

Overview

Runner Replicas

Runner Replicas transforms Enterprise Runners from single points of execution into distributed, fault-tolerant services by enabling multiple Runner instances - referred to as Replicas - to operate as a unified logical unit. Administrators can now deploy multiple Replicas of the same Runner across different hosts - either virtual machines or containers. Intelligent load balancing distributes job executions across healthy replicas while maintaining execution affinity for jobs that require filesystem consistency.
This enhancement eliminates single points of failure in the automation infrastructure, provides horizontal scalability for high-demand scenarios, and enables zero-downtime maintenance for patching, upgrading, or restarting individual Replica hosts while other Replicas seamlessly handle the workload, ultimately delivering the reliability and scale that mission-critical automation workflows demand.
