Build a Real Azure Hub-Spoke Network Without the Production Panic

Ever wanted to get hands-on with a proper Azure hub-spoke network architecture, but the thought of clicking through the portal for hours or worrying about runaway cloud costs made you close the tab? You're not alone. Setting up a realistic, production-like environment just for learning can feel like more trouble than it's worth.

That's where this lab comes in. It gives you a complete, deployable Azure landing zone with a hub-spoke topology, designed specifically for safe experimentation and learning. Think of it as a production-grade sandbox.

What It Does

This GitHub repository contains Terraform code that automates the deployment of a foundational Azure hub-spoke network. This is a common enterprise architecture where a central "hub" virtual network contains shared services (like firewalls, VPN gateways), and multiple "spoke" networks connect to it for isolation and management.

The setup includes core components like virtual networks, subnets, route tables, and a network virtual appliance (simulated with a Linux VM) in the hub. It builds the plumbing so you can focus on learning how traffic flows, how to implement network security, and how the pieces fit together, rather than on manual configuration.

Why It's Cool

The clever part is the balance it strikes. It's not an oversimplified tutorial diagram, nor is it a sprawling enterprise monster. It's a just-right implementation that mirrors real-world patterns while being constrained and clear.

First, it uses Terraform, which means you're learning infrastructure-as-code practices alongside the networking concepts. The code is modular and readable, so you can see exactly how the hub and spokes are linked.

Second, it's built for learning, not for running your company. The configuration includes sensible cost-control measures and uses standard, billable components in a way that minimizes surprise charges. It creates a real environment where you can test routing, poke at network security groups, and see the architecture in action, without the pressure of a live system.

How to Try It

Getting your own copy running is straightforward. You'll need an Azure account (free tier works, but you will incur small costs for the VMs and resources) and Terraform installed locally.

1. Clone the repo:

   git clone https://github.com/Jamonygr/azure-landing-zone-lab
   cd azure-landing-zone-lab
   

2. Follow the README: The repository's README.md has the detailed steps. The general flow is:
   • Authenticate Terraform to your Azure subscription (az login).
   • Run terraform init to set up the backend.
   • Review the plan with terraform plan.
   • Deploy it all with terraform apply.

Within 10-15 minutes, you'll have a full hub-spoke network ready to explore in your Azure portal. When you're done, remember to run terraform destroy to clean up all the resources and stop any accruing costs.

Final Thoughts

As a developer, understanding this kind of underlying platform architecture is incredibly powerful. It demystifies how your applications actually connect and communicate in the cloud. This lab is a fantastic, low-stakes tool for that. You can break it, fix it, and iterate on it, which is the best way to learn.

Don't just read about hub-spoke—deploy one, log into the virtual machines, and trace a route. This repo gives you the keys to do exactly that.
