Building a 3-Tier Web Application Architecture on AWS (Step-by-Step Guide)

Are you ready to design and deploy a production-ready architecture on AWS? In this guide, I’ll walk you through how I built a highly available, scalable 3-tier web application using AWS services and Terraform for Infrastructure as Code (IaC).


Git_Repo:- https://github.com/SNS-Srinivasu/3-Tier-Architecture

🧱 What We’ll Build

A robust and scalable 3-tier architecture consisting of:

  • VPC with Public and Private Subnets
  • Internet Gateway & NAT Gateways
  • Application Load Balancer (ALB)
  • Auto Scaling Group (ASG) with EC2 instances
  • Amazon RDS (MySQL) with optional Read Replica
  • Terraform to automate all infrastructure provisioning

pretty cool seeing all the aws parts come together - you think it’s the challenge or just habit that keeps people building out big setups like this?
