I. Amazon Elastic File System (Amazon EFS)
Amazon Elastic File System (Amazon EFS) is a set-and-forget file system that automatically grows and shrinks as you add and remove files. There is no need for provisioning or managing storage capacity and performance. Amazon EFS can be used with AWS compute services and on-premises resources. You can connect tens, hundreds, and even thousands of compute instances to an Amazon EFS file system at the same time, and Amazon EFS can provide consistent performance to each compute instance.
With the Amazon EFS simple web interface, you can create and configure file systems quickly without any minimum fee or setup cost. You pay only for the storage used and you can choose from a range of storage classes designed to fit your use case.
| Standard storage classes | One zone storage classes |
|---|---|
| EFS Standard and EFS Standard-Infrequent Access (Standard-IA) offer Multi-AZ resilience and the highest levels of durability and availability. | EFS One Zone and EFS One Zone-Infrequent Access (EFS One Zone-IA) provide additional savings by saving your data in a single availability zone. |
