Reduce Storage Costs with EFS
Amazon Elastic File System (Amazon EFS) provides a simple, serverless elastic file system that lets you share file data without provisioning or managing storage. In this lab, we modify three existing EC2 instances to use a shared EFS storage volume instead of duplicated Elastic Block Store volumes. This reduces costs significantly, as we only need to store data in one location instead of three. By the end of this lab, you will understand how to create EFS volumes and attach them to an EC2 instance.
