Deploying a Highly Available Web App on AWS Using Terraform

This article covers deploying a highly available web application on AWS using Terraform, evolving from a single-server setup to a clustered architecture with a custom VPC, public/private subnets, an Application Load Balancer, and an Auto Scaling Group across two Availability Zones. The deployment ensures application servers remain in private subnets for security while the load balancer handles internet traffic, and the code leverages variables and data sources for reusability.
