January 30, 2026 ยท View on GitHub

Build infrastructure as code with Terraform for cloud deployment.

Overview

Production-ready Terraform configurations for deploying cloud infrastructure. Uses modular design with reusable components, remote state management, and environment workspaces. Targets AWS but can be adapted for other cloud providers.

Features

  • Modular infrastructure design
  • Remote state with S3 and DynamoDB locking
  • Environment workspaces (dev, staging, prod)
  • VPC with public/private subnets
  • ECS/EKS for container orchestration
  • RDS database setup
  • ElastiCache for caching
  • ALB with SSL termination
  • IAM roles and policies
  • CloudWatch monitoring
  • Auto-scaling configuration
