Cloud Architecture with Terraform

Secure, scalable AWS infrastructure using Infrastructure as Code

Project Overview

Designed and deployed a secure three-tier AWS architecture using Terraform. The solution includes Public, Private, and Secure subnets, Application Load Balancer, Auto Scaling Group for application workloads, and a highly secured RDS database tier. A golden AMI was created using Packer to ensure consistency across deployments.

Architecture Highlights

Three-tier subnet architecture: Public, Private, and Secure
Internet Gateway and NAT Gateway for controlled connectivity
Application Load Balancer deployed across multiple AZs
Auto Scaling Group with private EC2 instances (no public IPs)
Golden AMI creation using Packer
RDS deployed in fully isolated secure subnet
Access to EC2 via AWS Systems Manager (SSM)
VPC Flow Logs enabled for monitoring and auditing

Security & Reliability

Strict network segmentation and least-privilege security groups
No direct internet access to application and database tiers
Highly available design spanning multiple Availability Zones
Infrastructure defined and version-controlled using Terraform
Repeatable, auditable, and environment-agnostic deployments
