Cloud Challenge Details

In this lab challenge, your AWS ELB skills are put to the test. You'll be given a requirement and you have to reach it using your knowledge of AWS ELB and other AWS services relevant to working with ELB. The Lab Challenge helps you understand the real-time scenarios.

A company XYZ is deploying a new web application. As a part of the infrastructure, they need a load balancer for their Testing Environment. Now your challenge is to build them a web server using an Application load balancer (ALB) with the below requirements. You need to distribute the traffic using Amazon EC2 Instances and Target Groups.

  1. Create a Security Group for the ALB and EC2, allowing HTTP and HTTPS in the inbound rule. Use this security group during both EC2 Instance and ALB creation.

  2. Create two EC2 Instances, one by one in two different AZ with t2.micro as instance type and Amazon Linux 2 as AMI. Use the User data mentioned below in the resources section. Use this same AZ during ALB creation.

  3. Create a target group and register both the EC2 Instances on port 80. Use this target group during ALB creation.

  4. Create an Application load balancer having the same AZ of EC2 Instances. Select Security group and Target group created in previous steps.

  5. Check the health of the registered instances in the target group.

  6. Copy and paste the ALB's DNS name in the browser and test the traffic shifting of EC2 Instances.

  7. Click on Validate to complete the challenge.
