Introduction to Amazon EFS

Amazon Elastic File System (EFS) is a scalable, fully-managed cloud-based file storage service provided by Amazon Web Services (AWS). It allows multiple EC2 instances to access a shared file system, which is ideal for use cases like web serving, content management, and data sharing across different applications. EFS provides the flexibility and scalability required to handle dynamic workloads and offers high availability and durability by storing data redundantly across multiple Availability Zones (AZs).

In this blog, we perform some task:

• Task 1: Create an Amazon EFS File System

• Task 2: Mount the EFS File System on EC2 Instances

• Task 3: Install Apache2 web server and host a website using aws EFS

Create an Amazon EFS File System

Step 1: Create a two EC2 instance

Step 2: Create an Amazon EFS File System

Navigate to the EFS Console:

1. Log in to the AWS Management Console and go to the EFS service.

   

2. Create a New File System:

   • Click on “Create file system.”

3. Network Setting

4. Review and create

Step 3: Configure Security Groups

Edit Security Groups:

Ensure the security groups associated with your EC2 instances allow inbound NFS traffic (port 2049).

Also, configure the EFS security group to allow inbound NFS traffic from the security groups of your EC2 instances.

Click on Create security group

Mount the EFS File System on EC2 Instances

1. Install NFS Utilities on both EC2 instances:

   sudo apt install nfs-common

   

   Go to your aws EFS ->> File system

   

   click the Attach option

   

   Copy the NFS client

   Go to your EC2-Instance and mount this to your directory.

   First, mkdir used to make a new directory

   

   

   REPEAT THE SAME STEPS IN OTHER EC2-INSTANCE ALSO,

   

   We can see that aws EFS allows multiple EC2 instances to access a shared file system

   

   Install Apache2 web server and host a website using aws EFS

   Set Up Apache Web Server in both AWS EC2 Linux (Ubuntu) Instance run below commands:

   Update packages with the command ‘sudo apt-get update’.

   Install Apache2 using ‘sudo apt-get install apache2’

   sudo systemctl start apache2’

   sudo systemctl enable apache2’

   Verify that Apache is running using the command ‘sudo systemctl status apache2’

   

   Copy the NFS client and mount to your /var/www/html directory.

2. 

   We move index.html file into /var/www/html

   

   Let’s also check this from web browser. Hit the public IPs of both the instances and see they are returning same data.

   

   

   Conclusion

   Amazon EFS is a powerful, scalable, and flexible file storage solution that integrates seamlessly with other AWS services. It simplifies file storage management, making it an excellent choice for applications requiring shared storage with high availability and durability. By following the practical steps outlined above, you can easily set up and use EFS in your AWS environment to enhance your application’s performance and reliability.
