🌐 Understanding Azure VM Networking

When deploying a Virtual Machine (VM) in Azure, configuring the network correctly is critical for connectivity, security, and performance. Azure provides a robust networking infrastructure, including:

  • Virtual Networks (VNets): Logical isolated networks that connect your Azure resources.
  • Subnets: Segments within a VNet to organize resources and apply network policies.
  • Network Security Groups (NSGs): Rules that control traffic flow to and from VMs.
  • Public IP Addresses: Enable internet access for your VMs.
  • Private IP Addresses: For internal communication within the VNet.

✅ Step-by-Step Configuration Guide

  1. Create a VNet:

    • Navigate to the Azure portal and select "Virtual Networks."
    • Define the VNet name, address space, and location.

  2. Configure Subnets:

    • Add subnets under the VNet to isolate workloads.
    • Example: 10.0.0.0/16 for the main subnet and 10.0.1.0/24 for the backend subnet.

  3. Assign IP Addresses:

    • Allocate public IPs for internet-facing VMs and private IPs for internal use.

  4. Set Up NSGs:

    • Create rules to allow or deny traffic based on protocols, ports, and source/destination.
    • Use Security_Group_Rules as a keyword for related images.

🔒 Best Practices for Secure Networking

  • Use Network Security Groups (NSGs) to restrict access to critical ports (e.g., SSH on port 22).
  • Implement Private Endpoint for secure connections to Azure services.
  • Regularly review and update firewall rules to minimize vulnerabilities.
