Terraform Multi-Environment Setup

This project provides a Terraform configuration for setting up infrastructure across multiple environments (development, staging, and production) in AWS. It follows best practices for infrastructure as code, allowing for scalable and repeatable deployments.

Features

• Multi-environment support (Dev, Staging, Prod)
• Amazon VPC setup with private and public subnets
• EC2 instance provisioning
• Elastic Load Balancer (ELB) configuration
• Secure access with Security Groups

Prerequisites

• Terraform installed (Install Guide)
• AWS CLI configured with appropriate credentials
• Remote backend (S3 + DynamoDB) for state management

Setup and Deployment

1. Initialize Terraform:

   terraform init

2. Select the desired environment (e.g., dev, staging, or prod):

   terraform workspace new dev  # Change directory to the desired environment

3. Plan the deployment:

   terraform plan

4. Apply the deployment:

   terraform apply -var-file=terraform.dev.tfvars

5. Destroy the infrastructure if needed:

   terraform destroy

AWS Architecture Overview

Below are the key AWS resources provisioned by this Terraform setup:

• VPC: A dedicated Virtual Private Cloud with private and public subnets
• ELB: Load balancer to distribute traffic
• EC2: Virtual machines for application workloads
• Security Groups: Firewall rules for secure access

Best Practices Followed

• Modular Terraform code for reusability
• Remote backend for state management
• Environment separation to ensure isolated deployments
• Parameterized configurations for flexibility

Future Enhancements

• Add auto-scaling for EC2 instances
• Implement IAM roles and policies for fine-grained access control
• Enhance monitoring with CloudWatch and logging setup
