It allows you to share files without provisioning or managing storage capacity, and it automatically scales as you add or remove files. EFS supports the Network File System (NFS) protocol and can be mounted by multiple Amazon EC2 instances, AWS Lambda functions, and other compute services
Amazon EFS lưu trữ và truy xuất dữ liệu tệp cho các instance Amazon EC2. EFS là dịch vụ lưu trữ tệp không máy chủ, hoàn toàn linh hoạt, cung cấp quyền truy cập tệp chia sẻ cho các dịch vụ AWS và tài nguyên tại chỗ.

Key Features
- Serverless and elastic: You don't need to provision or manage storage, and the file system grows and shrinks automatically.
- Shared access: It allows multiple AWS compute instances and on-premises servers to access the same file system simultaneously.
- Scalable: EFS can scale to petabytes of storage on demand without disrupting applications.
- High availability and durability: It is designed for high availability and durability, storing files redundantly across multiple availability zones.
- NFS support: It uses the NFSv4.0 and NFSv4.1 protocols, making it compatible with many existing applications and tools.
- Pay-as-you-go: You pay only for the storage you use.
- Throughput modes: You can choose between Bursting Throughput (default) and Provisioned Throughput (for applications that need high throughput).
- Integration: EFS integrates with other AWS services like IAM for access control, KMS for encryption, and CloudWatch for monitoring.
