The HashiCorp team has announced a Technical Preview of the Nomad Autoscaler, an open-source project that provides automatic scaling capabilities for workloads running on a Nomad cluster. The autoscaler can be easily deployed on Nomad and employs a plugin system to allow operators to customize its behavior. It is designed to address the need for automatic scaling in response to real-time demands, balancing resource utilization with necessary costs and scheduling contention. The autoscaler has been implemented as an external process interacting with a new Scaling Policy API in Nomad, providing multiple plugin systems for customizing its operation. Operators can run the autoscaler on Nomad, configure job specifications with autoscaling policies, and use observability tools to monitor scaling events. The feature is currently available as a tech preview, gathering feedback from the community before being officially released and supported by HashiCorp.
