Build a Scalable Web Application Using ALB and Auto Scaling Group
In this lab, you will deploy a highly available and scalable web application on AWS using EC2, an Application Load Balancer, and an Auto Scaling Group. You will launch EC2 instances with user data, configure security groups, create a load balancer to distribute traffic, and set up an Auto Scaling Group that automatically adjusts capacity.

Questions about this lab
Do I need my own AWS account?
No. When you start the lab, Cloud Arena gives you a real, temporary AWS account with its own login, locked to one region. You work in the real AWS Management Console, not a simulator.
Will AWS charge me anything?
No. Cloud Arena pays for the AWS resources, and everything you create is deleted automatically when you stop the lab or the session ends. Nothing is billed to you by AWS.
How long does the Build a Scalable Web Application Using ALB and Auto Scaling Group lab take?
Plan for about 120 minutes. The session timer is shown on screen, and every task is checked against your live AWS account when you click Verify.
How do I get access to this lab?
It is included in the AWS Certified Cloud Practitioner plan: a one-time payment for every lab in the path, 2 attempts per lab and a 7-day money-back guarantee. You can also start with the 5 free labs.
Does this lab help with the Cloud Practitioner (CLF-C02) exam?
Yes. It is part of the AWS Certified Cloud Practitioner path, which covers the hands-on skills behind the exam. Doing the task in a real account is what makes the questions easier to reason about.
