AWS Batch on EKS Adds Support for Unmanaged Compute Environments

Amazon Web Services has added support for unmanaged compute environments when running AWS Batch on Amazon EKS, giving customers more flexibility in how they operate container-based batch workloads. With the update, organizations can use AWS Batch to schedule and manage jobs on existing, self-managed EKS clusters rather than relying solely on AWS-managed compute environments. The capability is intended to support teams that require tighter control over cluster configuration, scaling policies or cost optimization strategies. This capability allows the creation of unmanaged compute environments through the CreateComputeEnvironment API and AWS Batch console using existing EKS clusters and a specified Kubernetes namespace to associate EKS nodes with.

As Kubernetes adoption has grown, many organizations have standardized on EKS while maintaining custom cluster configurations for networking, security, or specialized hardware. By supporting unmanaged compute environments on EKS, AWS Batch becomes more adaptable to heterogeneous Kubernetes setups. For platform and DevOps teams, the update enables consistent batch scheduling and job management while preserving existing cluster governance and operational practices. The update is available across all AWS regions where AWS Batch is available.
