# Elastic File System
|
|
|
|
Serverless file storage for sharing files without the need for provisioning or managing storage capacity and
|
|
performance.

|
## TL;DR
|
|
|
|
Built to scale on demand growing and shrinking automatically as files are added and removed.<br/>
|
|
Accessible across most types of AWS compute instances, including EC2, ECS, EKS, Lambda, and Fargate.
|
|
|
|
Supports the NFS v4.0 and v4.1 protocols.
|
|
|
|
Available file system types:
|
|
|
|
- _Regional_: redundant across **multiple** geographically separated AZs **within the same Region**.
|
|
- _One Zone_: data stored within a **single AZ**, with all the limits it implies.
|
|
|
|
Default modes:
|
|
|
|
- _General Purpose Performance_: ideal for latency-sensitive applications.<br/>
|
|
Examples: web-serving environments, content-management systems, home directories, and general file serving.
|
|
- _Elastic Throughput_: designed to scale throughput performance automatically to meet the needs of workloads' activity.
|
|
|
|
Provides file-system-access semantics like strong data consistency and file locking.<br/>
|
|
Supports controlling access to file systems through POSIX permissions.<br/>
|
|
Supports authentication, authorization, and encryption.
|
|
|
|
EFS supports encryption in transit and encryption at rest.<br/>
|
|
Encryption at rest is enabled when creating a file system. In such case, all data and metadata is encrypted.<br/>
|
|
Encryption in transit is enabled when mounting a file system. Client access via NFS to EFS is controlled by both IAM
|
|
policies and network security policies (i.e. security groups).
|
|
|
|
Windows-based EC2 instances are **not** supported.
