🚀 Deploy a Secure EC2 Web Server with Terraform, VPC, and Remote State on AWS

Are you looking to automate your AWS infrastructure and deploy a web server with best practices? In this guide, you'll learn how to use Terraform to:

• Provision a secure VPC with public/private subnets


• Launch an EC2 instance running Apache with a sample website


• Manage SSH keys and security groups


• Store your Terraform state remotely in S3 for safety and collaboration

Let's get started!

📦 What Does This Project Do?

• 
  Creates a VPC with public and private subnets across multiple Availability Zones


• 
  Sets up an Internet Gateway and routing for public subnets


• 
  Launches an EC2 instance in a public subnet


• 
  Configures a Security Group for SSH and HTTP access


• 
  Manages SSH Key Pairs for secure access


• 
  Provisions Apache Web Server with a sample website using a shell script


• 
  Stores Terraform state remotely in an S3 bucket for collaboration and safety

🛠️ Prerequisites

• 
  Terraform installed


• 
  AWS CLI installed and configured (aws configure)


• An AWS account with permissions to create EC2, VPC, and S3 resources

📁 File Overview

• 
  Provider.tf: AWS provider configuration


• 
  vpc.tf: VPC, subnets, internet gateway, and route tables


• 
  Instance.tf: EC2 instance definition and provisioning


• 
  KeyPair.tf: SSH key pair resource


• 
  SecurityGroup.tf: Security group for SSH/HTTP access


• 
  vars.tf: Variables for region, AMI, zones, etc.


• 
  backend.tf: Remote state backend (S3)


• 
  web.sh: Script to install Apache and deploy a sample website


• 
  .gitignore: Ignore sensitive files and Terraform state


• 
  terraform-vpc-ssh-key / .pub: SSH keys (do not commit private key!)

🚦 Quick Start

# 1. Clone the repo

git clone https://github.com/tej6667/terraform-aws-vpc-ec2-webserver.git



# 2. Initialize Terraform

terraform init



# 3. Review the plan

terraform plan



# 4. Apply the configuration

terraform apply

# Type 'yes' when prompted



# 5. Destroy resources when done

terraform destroy

# Type 'yes' when prompted

⚙️ Customization

• 
  Region & Zones: Edit vars.tf for your preferred AWS region and availability zones.


• 
  AMI: Update the amiID map in vars.tf for your region.


• 
  Security Group: Change allowed IPs in SecurityGroup.tf.


• 
  S3 Backend: Set your S3 bucket name in backend.tf.


• 
  SSH Key: Replace with your own key in KeyPair.tf and upload your public key.

📝 Notes & Best Practices

• Never commit AWS credentials or private keys.


• Review security group rules before applying.


• Remote state in S3 is critical for team collaboration and disaster recovery.


• Remember to destroy resources to avoid AWS charges.
