1. Creating a Virtual Network (vNet)

Overview

The objective of this exercise is to create a Virtual Network (vNet) with a default subnet using the Azure Portal, laying the foundation for a secure network architecture. You will also provision three servers having the roles Web Server, Reverse Proxy and Bastion Host respectively. Finally, firewall rules will be created to secure the network using Azure Network Security Groups (NSG)

2. Creating a Virtual Network with Enhanced Security

Overview

The objective of this exercise is to create a Virtual Network (vNet) with a subnet secured by a Network Security Group (NSG) attached to the subnet itself. You will also provision three servers with specific roles: Web Server, Reverse Proxy, and Bastion Host. Application Security Groups (ASGs) will be configured for the Reverse Proxy and Bastion Host, and all server configurations will be automated using cloud-init.
