AWS Secure Web Infrastructure

This project sets up a secure web infrastructure on AWS using Terraform and Ansible. It includes VPC, subnets, EC2 instances, security groups, and a Bastion host. Ansible is used to configure Nginx on the EC2 instances.

Prerequisites

• Terraform
• Ansible
• AWS account with appropriate permissions

Terraform Setup

1. Initialize Terraform:

   cd terraform
   terraform init

2. Apply Terraform Configuration:

   terraform apply

   This will create the VPC, subnets, EC2 instances, security groups, and Bastion host.

Ansible Setup

1. Update Inventory File:

   Update the inventory file with the public and private IPs of the EC2 instances.

2. Run Ansible Playbook:

   ansible-playbook -i ansible/inventory ansible/nginx_setup.yml

   This will install and start Nginx on the EC2 instances.

Outputs

After running Terraform, the following outputs will be available:

• VPC ID
• Public Subnet ID
• Private Subnet ID
• Public EC2 Instance ID and Public IP
• Private EC2 Instance ID
• Bastion Host ID and Public IP
• Security Group IDs

Clean Up

To destroy the infrastructure, run:

terraform destroy
