Objectives

You need to complete the following:

Create an EFS file system
Spin up two EC2 instances in two seperate AZs in the same region
Make sure you can SSH into both instances

Open that file on the EFS volume with Instance-2

You need to answer the following:

What are the use cases for EFS volumes?
From how many regions and availability zones can a single EFS volume be accessed?
What network protocol does EFS use?
How many instances can an EFS volume be mounted on simultaneously?
How is the throughput [speed] of an EFS volume determined?
What do the performance and throughput mode settings influence?
How can access to an EFS volume be limited?
Does EFS support security groups?
Does EFS support encryption at rest and in-transit?
What is EFS Infrequent Access (EFS IA)?
What is the operating system requirement for mounting an EFS volume?
What are the key differences between EFS and EBS volumes?

Make sure to expose the EFS volume to only and all the necessary availability zones.
Pre-built commands for mounting the EFS volume are provided in the volume's console.
Storing small amounts of data on an EFS volume can lead to performance issues.
