AWS EC2 Web Server Infrastructure - Part 1

🚀 Project Overview

This project is Part 1 in a series demonstrating infrastructure as code (IaC) using Terraform to provision AWS resources. This first implementation creates a basic EC2 instance with HTTP access, representing the starting point of a DevOps learning journey.

Key Components

• EC2 Instance: t2.micro instance running Amazon Linux 2023 AMI
• Security Group: Configured to allow HTTP ingress (port 80) and all egress traffic
• Infrastructure as Code: Basic infrastructure defined using Terraform

🔧 Prerequisites

• Terraform installed
• AWS CLI installed and configured with appropriate credentials
• AWS account with necessary permissions
• Git for version control

🔨 Installation & Usage

Setup

1. Clone the repository:

git clone https://github.com/senopaul/Server_1.git
cd Server_1

2. Initialize Terraform:

terraform init

3. Plan the infrastructure:

terraform plan

4. Apply the configuration:

terraform apply

5. When finished, destroy the infrastructure to avoid unnecessary charges:

terraform destroy

Key Operations

• Verify Security Groups: terraform state show aws_security_group.web_access
• Get EC2 Instance Public IP: terraform state show aws_instance.Server_1 | grep public_ip
• Access the web server: After deployment, you can access the web server via HTTP at the EC2 instance's public IP address

📋 Current Features

• Basic EC2 Instance: Deploys a t2.micro EC2 instance with Amazon Linux 2023
• HTTP Access: Security group configured to allow HTTP traffic on port 80
• Outbound Traffic: All outbound traffic allowed from the EC2 instance
• AWS Region: Deployed in the us-east-1 region
• Infrastructure as Code: Complete definition of infrastructure using Terraform

🔒 Security Considerations

• Security Groups: Currently configured to allow only HTTP traffic (port 80)
• Default VPC: Uses the default VPC and its security settings
• AWS Credentials: Uses AWS CLI credentials, no hardcoded secrets in the code

🚧 Future Improvements

This is Part 1 of a series. Future parts will implement:

• SSH access configuration
• HTTPS support with proper certificates
• Custom VPC with public and private subnets
• Variable definitions for better customization
• Output values for easy reference
• State management with S3 and DynamoDB
• Auto-scaling for high availability
• Monitoring and alerting
• More comprehensive security controls

📝 Learning Journey

This project marks the beginning of my DevOps journey, starting with the basics and building toward more complex implementations.
