How To Create An Amazon EFS File System By Raj Gupta

Amazon EFS enables you to create a file system that multiple instances can mount and access at the same time. This is same as like external hard disk.

1. Open the Amazon Elastic File System console at https://console.aws.amazon.com/efs/
2. Choose Create file system.
3. On the Configure file system access page, do the following:

• For VPC, select the VPC to use for your instances. 
• For Create mount targets, select all the Availability Zones. 
• For each Availability Zone, ensure that the value for Security group is the security group that you created. 
• Choose Next Step.

4. On the Configure optional settings page, do the following: 

• For the tag with Key=Name, type a name for the file system in Value. 
• For Choose performance mode, keep the default option, General Purpose. 
• Choose Next Step. 

5. On the Review and create page, choose Create File System.

6. After the file system is created, note the file system ID, as you'll use it later
