Project Overview

A robust, self-healing infrastructure solution built with Terraform that demonstrates modern cloud architecture principles. The system automatically recovers from failures, scales based on demand, and maintains high availability through redundancy and intelligent load balancing.

Key Features & Achievements
  • Provisioned a fault-tolerant web application architecture with Terraform (IaC).
  • Configured Auto Scaling Group (ASG) + Application Load Balancer (ALB) for automatic recovery of failed instances.
  • Defined IAM roles and outputs for secure, repeatable provisioning of cloud infrastructure.
  • Documented architecture for scalability, resilience, and high availability.
