Automate Cloud Infrastructure with Terraform (IaC)

Use Terraform to provision, manage, and destroy cloud resources programmatically. Build reusable modules and ensure consistency in deploying cloud environments across stages.

Why Use Terraform for IaC?

Terraform allows infrastructure to be defined in code and treated as part of the software development lifecycle. It eliminates manual provisioning steps, supports multiple cloud providers, and offers automation, repeatability, and team collaboration.

Project Objective

Set up an automated infrastructure pipeline using Terraform to provision a VPC, subnets, EC2 instances (or GCP/Azure equivalents), security groups, databases, and storage buckets — all through modular and parameterized code.

Key Features to Build

Modular Infrastructure Definition

Split infrastructure components like VPC, compute, storage, and IAM into reusable Terraform modules.

Parameterization and Environment Variables

Use `terraform.tfvars` and input variables to manage configurations per environment (dev/staging/prod).

Provisioning with Remote Backends

Store Terraform state remotely (e.g., in S3 or GCS) for safe team collaboration and rollback support.

Deployment Automation via CI/CD

Integrate Terraform with GitHub Actions or Jenkins for automated infrastructure deployments on code push.

Architecture Overview

You’ll define all infrastructure resources (VPC, subnets, servers, DBs) in `.tf` files and deploy to a cloud provider. The setup will include separation of variables, local and remote state management, and a `terraform plan → apply` pipeline tied to version control.

Provider: AWS / GCP / Azure
Resources: EC2, VPC, S3, IAM, RDS, Lambda (or GCP equivalents)
State Management: Remote backend with locking
Security: Secrets via environment variables or Vault integration
CI/CD: GitHub Actions / GitLab CI for Terraform automation

Recommended Tech Stack

Terraform CLI & Core

Terraform 1.x+, HCL (.tf files), local backend for dev, remote for production

Cloud Providers

AWS (VPC, EC2, S3, IAM), GCP (GCE, Storage), Azure (VM, Blob)

CI/CD Integration

GitHub Actions, GitLab CI/CD, Jenkins (with Terraform plugins)

Secrets & Vaults

AWS Secrets Manager, HashiCorp Vault, dotenv CLI for sensitive values

Development Roadmap

1. Install Terraform & Configure Provider

Install Terraform CLI and configure cloud provider credentials locally.

2. Define Basic Resources

Start with a basic EC2 instance or storage bucket and test `plan`/`apply` cycle.

3. Modularize Infrastructure

Split resources into modules and enable parameterization using input variables.

4. Implement Remote State

Configure remote state backend in S3/GCS with locking for collaboration safety.

5. Automate via GitHub Actions

Add CI pipelines to validate, plan, and apply infrastructure changes automatically.
