Multi-Cloud-VPN

This project establishes a secure Multi-Cloud VPN connection between AWS and Azure, enabling seamless communication across both cloud environments. Built entirely using Terraform and modular infrastructure, this solution connects workloads across cloud boundaries—laying the groundwork for highly available, hybrid-cloud architectures.

🌐 Project Overview

The goal was to securely link an Azure Virtual Network with an AWS VPC, creating a private tunnel that enables services in each cloud to communicate. This was tested by deploying:

• A WordPress application on an Azure VM
• A MySQL RDS database in AWS

The project demonstrates core platform engineering skills across cloud networking, automation, infrastructure modularity, and secure connectivity.

🔧 Key Features

• Cloud Interconnectivity
  • Azure → AWS site-to-site VPN
  • IPsec/IKE configuration via Terraform
• Compute Resources
  • Azure Linux VM (WordPress host)
  • AWS EC2 (optional testing)
• Data Services
  • AWS RDS (MySQL) with restricted private access
• IaC Implementation
  • Fully modular Terraform structure
  • Reusable modules for VPC/VNet, subnets, VPN Gateways, route tables
• Planned Automation
  • Ansible playbooks to automate WordPress deployment and DB integration (WIP)

🧠 Skills Demonstrated

• Terraform Modules (reusable infrastructure design)
• Site-to-Site VPN (Azure Local Network Gateway + AWS Virtual Private Gateway)
• Private Networking (subnetting, route propagation, BGP basics)
• Multi-cloud Infrastructure as Code
• Secure connectivity testing and validation
• Terraform documentation and variable design
