EFS Practical

Introduction

In the widget below, we’ll take the following steps to create an EFS and access it from two EC2 instances:

• Create a security group for EC2 with SSH access.
• Create a security group for EFS to allow NFS connections from the EC2 security group.
• Create an EC2 key pair.
• Launch two EC2 instances in two different subnets of the region.
• Create an EFS file system.
• Create EFS mount points in these subnets so that EC2 instances can connect to the EFS.
• Use the SSH command in Instance A to:
  • Create a directory /efs-mount-point.
  • Mount EFS to this directory.
  • Create a file in the EFS.
• Use the SSH command in Instance B to:
  • Create a directory /efs-mount-point.
  • Mount EFS to this directory.
  • View the file created by EC2 Instance A.

Note: Both EC2 instances share the file system and data added to the file system.
