III. Introduction to EFS

Amazon Elastic File System (Amazon EFS) provides a simple, scalable, resilient file system for Linux-based workloads that can be used with AWS cloud services and local resources. It scales to the PB level on demand without interrupting the application, automatically expanding or shrinking when you add or delete files, allowing your application to get the storage it needs when needed. It is designed to provide massively parallel shared access mode for thousands of Amazon EC2 instances, allowing your application to achieve high levels of total throughput and IOPS in a consistent, low-latency state. Amazon EFS is a fully managed service that does not require changes to existing applications and tools and provides access through a standard file system interface for seamless integration. Amazon EFS provides standard and infrequently accessed storage classes. By using lifecycle management, files that have not been accessed for 30 days can be automatically moved to cost-optimized infrequently accessed storage classes, allowing you to easily store and access active infrequently accessed file system data in the same file system. at the same time, storage costs are reduced by up to 85%. Amazon EFS is a regional service for storing data in multiple availability zones (AZ) to provide high availability and persistence. You can access file systems across availability zones, zones, and VPC, and share files between thousands of Amazon EC2 instances and local servers through AWS Direct Connect or AWS.
