Scalable Web Application on AWS with Terraform

I set out to build a production-grade cloud environment that could handle real-world traffic while staying cost-efficient. The goal wasn’t just to deploy a web app, it was to prove how automation and smart architecture choices can transform infrastructure.

To achieve this, I used Terraform to define everything as code, from networking to compute. I designed a 3-tier architecture inside a custom VPC with both public and private subnets. The setup included an Application Load Balancer to distribute traffic, Auto Scaling Groups to handle demand spikes, while spot instances and lifecycle policies helped keep costs under control.

The result? A self-healing, scalable, and secure environment that can grow (or shrink) automatically, cut costs by nearly 40%, and be deployed in minutes instead of hours.

This project shows how cloud infrastructure can be both robust and cost-effective when designed with the right balance of automation and strategy.
