PRODUCTION TERRAFORM MODULES LAB

Build a real-world architecture using modules: VPC (network) Security Group EC2 (app layer) ALB (load balancer) Multi-environment structure (dev/prod) Remote-ready structure (like companies) 🏗️ REAL-WORLD STRUCTURE (VERY IMPORTANT) terraform-production-lab/ │ ├── infra-modules/ # reusable modules (shared) │ ├── vpc/ │ ├── ec2/ │ ├── security-group/ │ └── alb/ │ └── infra-live/ # environments (what we deploy) ├── dev/ └── prod/ 🧠 WHY THIS STRUCTURE (INTERVIEW GOLD) Companies separate code: 1. infra-modules reusable versioned no environment-specific values 2. infra-live environment-specific (dev, prod) small configs calls modules 👉 This avoids duplication and supports scaling 📁 STEP 1 — CREATE STRUCTURE mkdir -p terraform-production-lab/infra-modules/{vpc,ec2,security-group,alb} mkdir -p terraform-production-lab/infra-live/{dev,prod} cd terraform-production-lab 🔷 MODULE 1 — VPC (Production Version) infra-modules/vpc/main.tf resource "aws_vpc" "this" { cidr_block = var.cidr_block tag
