Overview of Project

Scenario

A growing technology company manages its AWS infrastructure manually through the AWS Console. As the environment grows, this approach starts causing serious problems:

• Infrastructure changes are undocumented
• Environments drift over time
• Reproducing setups across accounts is difficult
• Rollbacks are risky and error-prone
• Collaboration between engineers is inconsistent

The engineering team wants a reliable, repeatable, and version-controlled way to manage AWS infrastructure.

To solve this, they decide to adopt Infrastructure as Code (IaC) using Terraform.

Your Role as the DevOps Engineer

Your role is to design and build AWS infrastructure entirely using Terraform, following real-world DevOps best practices.

You are responsible for:

• Writing Terraform code to provision AWS resources
• Managing infrastructure state safely using a remote backend
• Building infrastructure incrementally instead of all at once
• Refactoring Terraform code into reusable modules
• Understanding how Terraform tracks, plans, and applies changes

This mirrors how DevOps engineers manage infrastructure in production teams.

Our Solution

You will use Terraform to provision and manage AWS infrastructure from scratch.

The solution includes:

• A Terraform project structured for real environments
• A remote backend using Amazon S3 and DynamoDB for state and locking
• Core AWS infrastructure built step by step
• Refactored Terraform code using modules for reusability
• Safe change management using terraform plan and terraform apply

Instead of clicking in the AWS Console, Terraform becomes the single source of truth for infrastructure.

About the Project

In this hands-on project, you will learn how to manage AWS infrastructure using code, not the console.

You will understand:

• How Terraform interacts with AWS APIs
• How Terraform state works and why remote state is critical
• How dependencies are resolved automatically
• How to safely modify infrastructure without accidental deletion
• How modular Terraform code is structured in real teams

By the end of this project, you’ll be able to read, write, and reason about Terraform code with confidence.

Steps To Be Performed 👩‍💻

We’ll complete the project in the following stages:

1. Understand and configure Terraform locally
2. Configure a remote backend using S3 and DynamoDB
3. Build AWS infrastructure incrementally using Terraform
4. Review and apply changes safely using terraform plan
5. Refactor infrastructure into Terraform modules

Each step focuses on why Terraform behaves the way it does, not just running commands.

Services Used 🛠

• Terraform - Infrastructure as Code tool
• Amazon S3 - Store Terraform remote state
• Amazon DynamoDB - State locking and consistency
• Amazon VPC - Networking foundation
• Amazon EC2 - Compute resources
• Security Groups - Network access control
• AWS IAM - Permissions for Terraform operations

Estimated Time & Cost ⚙️

• Estimated Time: 3 - 4 hours
• Cost: $0-$2 (within AWS Free Tier when cleaned up)

➡️ Final Result

At the end of this project, you’ll have:

• AWS infrastructure created entirely using Terraform.
• Remote state management with locking.
• Modular, reusable Terraform code with a strong foundation for managing real-world cloud infrastructure.
