Enhancing co-located Kubernetes Pod data access with Amazon EBS Node-Local volumes

This article explains how to use Amazon EBS Node-Local Volumes to enable secure, shared node-local storage for co-located Kubernetes pods on Amazon EKS, eliminating operational complexity while maintaining performance and security.

• Multiple pods on same node can share cached datasets without redundant network transfers
• Solves performance challenges of read-heavy workloads like ML inference and HPC at scale
• Safer alternative to hostPath volumes; avoids complex per-node PersistentVolume management
• Single cluster-wide PV/PVC maps to node-specific EBS volumes automatically
• Each node independently mounts its own local EBS device; data isolated between nodes
• Step-by-step walkthrough covers cluster creation, PV/PVC setup, and data sharing verification
• Available in EBS CSI driver v1.53.0 and later

Amazon EBS Node-Local Volumes simplify shared node-level caching for Kubernetes workloads, improving performance for ML inference, analytics, and HPC applications without operational overhead.
