A Step-By-Step Guide to Multi Hub and Spoke Topology using Azure Firewalls
Introduction
Today, cloud computing is becoming increasingly popular as organizations look to reduce costs while scaling their infrastructure. As such, many organizations are turning to cloud-based services such as Microsoft Azure for their business needs. Azure Firewall is a cloud-native network security solution that provides customers with increased control, visibility, and protection for their applications and data. This blog post will provide a step-by-step guide to deploying a multi-hub and spoke topology using Azure Firewall.

What is Multi Hub and Spoke Topology?
A multi-hub and spoke topology is an architecture in which multiple hubs are connected to each other through a network of spokes. The network is arranged in a star-like pattern, with the hubs at the center and the spokes extending outward. The spokes are responsible for connecting the hubs to each other, as well as to the external networks. This architecture provides a number of advantages, including increased scalability, flexibility, and improved security.

What are the Benefits of Using Azure Firewalls?
Azure Firewall provides customers with a comprehensive set of network security capabilities, including the ability to control and monitor inbound and outbound traffic. It also provides features such as threat intelligence and URL filtering. Additionally, Azure Firewall is highly scalable, allowing customers to add additional resources as needed. Finally, Azure Firewall is cloud-native, meaning it can be deployed quickly and easily without additional hardware or software.

Step-By-Step Guide to Deploying a Multi Hub and Spoke Topology Using Azure Firewall
Step 1: Create the Hub and Spoke Networks
The first step in deploying a multi-hub and spoke topology using Azure Firewall is to create the hub and spoke networks. This can be done by creating virtual networks (VNets) for each hub and spoke. For each VNet, you will need to specify the subnets, CIDR blocks, and associated IP address ranges.

Step 2: Configure the Firewall
The next step is to configure the Azure Firewall. This can be done by creating an Azure Firewall resource in the Azure Portal. You will then need to configure the Azure Firewall settings, such as rules, application control, threat intelligence, and URL filtering. Additionally, you will need to configure the hub and spoke networks to ensure the traffic is routed correctly.

Step 3: Connect the Hubs and Spokes
Once the Firewall has been configured, the next step is to connect the hubs and spokes. This can be done by creating virtual network peering between the hubs and spokes. This will allow the traffic to be routed between the hubs and spokes securely and efficiently.

Step 4: Configure the Firewall Rules
The final step is to configure the firewall rules. This can be done by creating rules in the Azure Firewall resource. The firewall rules can be used to control the traffic between the hubs and spokes, as well as to external networks. The rules can also be used to block certain types of traffic or to allow certain types of traffic.

Conclusion
This blog post has provided a step-by-step guide to deploying a multi-hub and spoke topology using Azure Firewall. By following the steps outlined in this blog post, customers can quickly and easily deploy a secure, scalable, and flexible network architecture that meets their business needs.
