[AWS] Elastic File System (EFS)

Elastic File System (EFS) is a scalable managed service that implements the Network File System (NFSv4).

File systems can be mounted on multiple Linux instances at the same time. -> shared media, home folder, shared documents.
It can be accessed in the VPC, across the VPC, and even from outside of VPC through Direct Connect.
EFS is built to scale while maintaining low latency and high throughput. It can support thousands of current NFS connections.
EFS is a regional service that stores data across multiple AZs for high availability and durability.
EFS supports Read after Write consistency.

Every EC2 instance must have a root volume, which may or may not be EBS (Elastic Block Store).
By default, an EBS root volume will be deleted when the instance is terminated. You can change the setting to make EBS volumes persistent.
You can attach additional EBS volumes to instances, and they are not deleted when the instance is terminated.
