AWS Parallel Computing Service (PCS) now supports rotation of cluster secret keys

AWS Parallel Computing Service (PCS) now supports rotation of cluster secret keys using AWS Secrets Manager, enabling you to update the secure credentials used for authentication between Slurm controller and compute nodes without creating a new cluster. Regularly rotating your Slurm cluster secret keys strengthens your security posture by reducing the risk of credential compromise and ensuring compliance with best practices. This helps keep your HPC workloads and accounting data safe from unauthorized access.

PCS is a managed service that makes it easier to run and scale high performance computing (HPC) workloads on AWS using Slurm. With the support of cluster secret rotation in PCS, you can strengthen your security controls and maintain operational efficiency. You can now implement secret rotation as part of your security best practices while maintaining cluster continuity.

This feature is available in all AWS Regions where PCS is available. You can rotate cluster secrets using either the AWS Secrets Manager console or API after preparing your cluster for the rotation process. Read more about PCS support for cluster secret rotation in the PCS User Guide.
