How to Configure Azure Virtual Networks

This section provides step-by-step guides and best practices for configuring and managing Azure Virtual Networks (VNets). VNets are the fundamental building blocks for your private network in Azure, enabling you to create isolated and secure network environments for your cloud resources.

Key Scenarios Covered:

  • Creating and deploying new VNets.
  • Defining and managing subnets for resource organization.
  • Configuring IP addressing schemes, including public and private IPs.
  • Implementing network security using Network Security Groups (NSGs) and Azure Firewall.
  • Establishing connectivity between VNets and on-premises networks using VPN Gateway or ExpressRoute.
  • Setting up routing for traffic flow within and across VNets.

Common Tasks and Scenarios

1. Creating a Virtual Network

Learn how to create a new VNet using the Azure portal, Azure CLI, or Azure PowerShell. This includes defining the address space and regions.

2. Configuring Subnets

Subnets divide your VNet into smaller segments, allowing for better organization and security. This guide covers creating, modifying, and managing subnets.

3. Setting Up Network Security Groups (NSGs)

NSGs act as a basic firewall at the network interface or subnet level, controlling inbound and outbound traffic. Discover how to create and apply NSG rules.

4. Peering Virtual Networks

VNet peering allows you to connect VNets in the same or different Azure regions, enabling seamless communication between them. This section explains how to set up peering connections.

5. Connecting to On-Premises Networks

Extend your on-premises network to Azure by creating secure connections. This includes using Site-to-Site VPNs or Azure ExpressRoute for dedicated private connections.

6. Implementing Azure Firewall

Azure Firewall is a managed, cloud-based network security service that protects your VNet resources. Learn how to deploy and configure Azure Firewall for centralized threat protection.

Best Practice: Network Design

When designing your VNets, consider implementing a hub-and-spoke topology. This architecture involves a central hub VNet that interconnects with multiple spoke VNets, simplifying management and improving security.
