Three, EFS Introduction
Amazon Elastic File System (Amazon EFS) is a Linux-based workloads to provide a simple, scalable, resilient file system, it can be used with AWS cloud services and local resources. It can be expanded without interrupting applications on-demand to the PB level automatically scale up or down as you add or delete files, so that your applications have the required storage when needed. It is designed to provide shared access to massively parallel model for thousands of Amazon EC2 instances, allow your applications to achieve high levels of total throughput and IOPS in a consistent, low-latency states. Amazon EFS is a fully managed service, it does not require existing applications and tools to make changes, and provides access through a standard file system interface for seamless integration. Amazon EFS offers standard and infrequent access storage class. By using lifecycle management, can be 30 days file is not accessible to automatically move to cost-optimized infrequently accessed storage class, so you can easily store and access activities in the same file system are not regularly access the file system data, while storage costs reduce up to 85%. Amazon EFS data stored in a plurality of available area (AZ) is used to provide high availability service area and durability. You can cross the available area, regional and VPC file system access and ××× can share files between the local server and in thousands of Amazon EC2 instance via AWS Direct Connect or AWS.
