The EC2 Instance Store CSI driver plugin, which allows Kubernetes to utilize EC2 instance store volumes as persistent volumes, was made generally available as an installable add-on via the Amazon EKS console and AWS CLI. This simplifies attachment and lifecycle management of NVMe-based ephemeral storage within EKS clusters.
These instance store volumes provide high-performance, physically attached block storage suitable for applications needing fast local I/O. General availability across commercial AWS regions standardized access and operational control, facilitating Kubernetes storage orchestration on ephemeral AWS resources.
