Amazon Elastic File System (Amazon EFS) provides a simple, serverless, set-and-forget elastic file system for use with AWS Cloud services and on-premises resources. It is built to scale on demand to petabytes without disrupting applications, growing and shrinking automatically as you add and remove files, eliminating the need to provision and manage capacity to accommodate growth. Amazon EFS has a simple web services interface that allows you to create and configure file systems quickly and easily. The service manages all the file storage infrastructure for you, meaning that you can avoid the complexity of deploying, patching, and maintaining complex file system configurations.

With Amazon EFS, you pay only for the storage used by your file system and there is no minimum fee or setup cost. Amazon EFS offers a range of storage classes designed for different use cases. These include:

  • Standard storage classes – EFS Standard and EFS Standard–Infrequent Access (Standard–IA), which offer multi-AZ resilience and the highest levels of durability and availability.

  • One Zone storage classes – EFS One Zone and EFS One Zone–Infrequent Access (EFS One Zone–IA), which offer customers the choice of additional savings by choosing to save their data in a single Availability Zone.

Steps to create and access EFS.

Create EC2 instances (Let's create 2 EC2 instances) and Open the NFS firewall to Anywhere.

Create a directory called efs and run the below command.

   yum install -y amazon-efs-utils

Select EFS service in AWS and create a file system.

Follow the instruction as mentioned on the attached page of the EFS and run those commands on EC2 instances

After that you will be able to share the files.
