### EFS Basics
- 📒 [Homepage](https://aws.amazon.com/efs/) ∙ [User guide](http://docs.aws.amazon.com/efs/latest/ug) ∙ [FAQ](https://aws.amazon.com/efs/faq/) ∙ [Pricing](https://aws.amazon.com/efs/pricing/)

- It is designed to be highly available and durable and each EFS file system object is redundantly stored across multiple availability zones.
- EFS is designed to be used as a shared network drive and it can automatically scale up to petabytes of stored data and thousands of instances attached to it.
- EFS can offer [higher throughput](http://docs.aws.amazon.com/efs/latest/ug/performance.html) (multiple gigabytes per second) and better durability and availability than EBS (see [the comparison table](#storage-durability-availability-and-price)), but with higher latency.

### EFS Gotchas and Limitations
- 🔸 A number of NFSv4.1 features are [not supported](http://docs.aws.amazon.com/efs/latest/ug/nfs4-unsupported-features.html) and there are some [limits](http://docs.aws.amazon.com/efs/latest/ug/limits.html) to the service.
- 🔸 As of 2017-08, EFS offers disk level encryption for new drives. For file systems created before that date, encryption can only be achieved by moving the data to a new EFS.
