AWS Project 4 | Scale Web App Using ALB & ASG | Auto Scaling + Load Balancer Tutorial (Step-By-Step)

Welcome to AWS Project 4!
In this advanced hands-on cloud project, you will learn how to deploy and scale a highly available web application using EC2, Application Load Balancer - ALB, Auto Scaling Group - ASG, AMI, and Launch Templates.

We’ll also perform load testing to verify automatic scaling and high availability. This is a must-learn project for DevOps, Cloud Engineers, and AWS beginners building real-world portfolio projects.

What You Will Learn
— Launching and configuring EC2 web servers
— Installing and testing HTTPD
— Creating custom AMIs
— Setting up Target Groups
— Creating an Application Load Balancer - ALB
— Creating a Launch Template
— Creating an Auto Scaling Group - ASG
— Performing load testing using Apache Benchmark - ab
— Auto-recovery using ASG health checks
— Achieving scalability, redundancy & high availability

AWS Services Used
— Amazon EC2
— Application Load Balancer - ALB
— Auto Scaling Group - ASG
— Amazon Machine Image - AMI
— Launch Templates

Steps Covered
— Launch & Test EC2 Web Server
• Install httpd
• Modify /usr/share/httpd/noindex/index.html
• Create a custom AMI
— Create AMI & Launch Another Server
• Launch a new EC2 using AMI
• Verify application output
— Configure Load Balancer
