Previously available for Fargate and ECS Managed Instances, Amazon ECS extended Amazon S3 Files support to the EC2 launch type. This enables containerized applications running on EC2 to access S3 data with full file system semantics without modifying application code or duplicating data.
Built on Amazon EFS technology, S3 Files provide low-latency, standard file system access directly to S3 bucket content. This capability simplifies AI, data processing, and file-based workloads across various ECS deployment options, unifying developer experience and data access methods across AWS compute environments.
