Day-41: Setting up an Application Load Balancer with AWS EC2 🚀 ☁

What is Load Balancing?

Load balancing is the distribution of workloads across multiple servers to ensure consistent and optimal resource utilization. It is an essential aspect of any large-scale and scalable computing system, as it helps you to improve the reliability and performance of your applications.

Elastic Load Balancing:

Elastic Load Balancing (ELB) is a service provided by Amazon Web Services (AWS) that automatically distributes incoming traffic across multiple EC2 instances. ELB provides three types of load balancers:

🎯 Today's Tasks:

Task 1:

Launch 2 EC2 instances with an Ubuntu AMI and use User Data to install the Apache Web Server.
If You Don't Know How to create a template then Read My Previous Blog.

Script for Apache installation below.

  #!/bin/bash

   sudo apt-get update -y
   sudo apt-get install -y apache2
   sudo systemctl start apache2
   sudo systemctl enable apache2

You can see two instances are created.

Copy the public IP address of your EC2 instances and run in a new browser by putting :80 in the last of the public IP to check whether the Apache web is installed or not.

EC2-1

EC2-2

Modify the index.html file to include your devops line so that when your Apache the server is hosted and do it for 2nd instance which includes " Developer help in developing APP ".

Connect Instances using SSH.

Go inside the /var/www/html path and edit the index.html file

While editing the index.html file login as root then proceed further step.

EC2-1

 sudo su
 cd /var/www/html
 rm index.html
 vim index.html

 <!DOCTYPE html>
 <html>
 <head>
   <title>Display Name</title>
   <style>
     body {
       background-color: blue;
     }

     .name {
       color: white;
       font-size: 24px;
       font-weight: bold;
       text-align: center;
       margin-top: 100px;
     }
   </style>
 </head>
 <body>
   <div class="name">Hey! Devops engineers helps in automating the task</div>
 </body>
 </html>

EC2-2

 ubuntu@ip-172-31-34-222:~$ sudo su
 root@ip-172-31-34-222:/home/ubuntu# cd /var/www/html
 root@ip-172-31-34-222:/var/www/html# ls
 index.html
 root@ip-172-31-34-222:/var/www/html# rm index.html 
 root@ip-172-31-34-222:/var/www/html# vim index.html

 <!DOCTYPE html>
 <html>
 <head>
   <title>Display Name</title>
   <style>
     body {
       background-color: orange;
     }

     .name {
       color: white;
       font-size: 24px;
       font-weight: bold;
       text-align: center;
       margin-top: 100px;
     }
   </style>
 </head>
 <body>
   <div class="name">Hey! Developer helps in developing the App </div>
 </body>
 </html>

Task 2:

Create an Application Load Balancer (ALB) in EC2 using the AWS Management Console.

Click on "Load Balancers" in the left-hand navigation menu and then click the "Create Load Balancer" button

Select "Application Load Balancer" as the load balancer type and click "Create".

You need to Create a target group first by clicking on the below-marked option.

By clicking on Target group you will get the below page. Click on Create target group option. (Add EC2 instances you launch in task-1 to the ALB as target groups.)

Now You have to create security Group for load balancer. Bydefault AWS provides you a group But it Good practice to create new one so click on Create New Security Group in Security Group Section. It will take you to the new tab on browser. Fill your group name as you want & give Description. Set Inbound Rule to HTTP port 80 And keep rest all by default and click on create group.

Now you Successfully Created Load balancer for EC2 instance. click on view load balancer and see the all things about your Load balancer.

Now Its Time to test your Load Balancer. Copy the DNS name from Load balancer Description and paste in new browser tab and refresh again and again DNS URL.

Verify that the ALB is working properly by checking the health status of the target instances and testing the load-balancing capabilities.
