EFS STORAGE

What is EFS storage in AWS? 

• Amazon EFS
  S is a regional service storing data within and across multiple Availability Zones (AZs) for high availability and durability. 
• Amazon EC2 instances can access your file system across AZs, regions, and VPCs, while on-premises servers can access using AWS Direct Connect or AWS VPN.

How does AWS EFS work? 

• You can create a file system, mount the file system on an Amazon EC2 instance, and then read and write data to and from your file system. 
• You can mount an Amazon EFS file system in your VPC, through the Network File System versions 4.0 and 4.1 (NFSv4) protocol.
