Welcome to the Azure Virtual Network Best Practices guide. Whether you are new to Azure or an experienced user, understanding best practices for virtual networks is crucial for creating a secure and scalable network infrastructure.

Best Practices Overview

  • Network Security: Implementing strong security measures is essential for protecting your virtual network.
  • Scalability: Design your network to handle growth and changing demands.
  • High Availability: Ensure your network is resilient and can recover from failures.

Network Security

  1. Use Private and Public IP Addresses Wisely: Allocate private IP addresses for internal resources and public IP addresses for exposed services.
  2. Implement Network Security Groups (NSGs): NSGs allow you to control inbound and outbound traffic at the subnet level.
  3. Utilize Virtual Private Networks (VPNs): VPNs provide secure connectivity to your virtual network from remote locations.

Scalability

  1. Design for Scale: Plan your network architecture to accommodate growth.
  2. Use Azure Load Balancers: Distribute traffic across multiple VMs to improve performance and availability.
  3. Implement Azure Virtual Hub: Connect multiple Azure regions and on-premises networks for global connectivity.

High Availability

  1. Deploy VMs Across Multiple Availability Zones: Protect against datacenter outages by deploying VMs across different zones.
  2. Use Azure Site Recovery: Ensure your virtual machines can be quickly restored in case of a disaster.
  3. Implement Azure Traffic Manager: Route traffic to the closest available endpoint to improve performance and availability.
