Creating and managing a virtual network in Azure is essential for ensuring a secure, scalable, and reliable cloud infrastructure. Below are some best practices to consider when working with Azure Virtual Networks.

Network Topology

  • Single Subnet: For simple applications, a single subnet can be sufficient. However, for more complex scenarios, it is recommended to use multiple subnets to segregate different types of traffic.
  • Hub and Spoke Model: This model involves a central hub that connects to various spoke networks. It is ideal for scenarios where you need to connect multiple locations or services.

Security

  • NSGs (Network Security Groups): Use NSGs to control inbound and outbound traffic at the subnet level. It is essential to define strict rules to protect your network from unauthorized access.
  • VNet Peering: VNet peering allows you to connect two virtual networks within the same region securely. This can be useful for sharing resources between different teams or departments.

Performance

  • Use Premium Virtual Machines: Premium virtual machines provide higher network performance, lower latency, and lower jitter compared to standard virtual machines.
  • Implement Load Balancing: Load balancing distributes incoming network traffic across multiple VMs, improving performance and availability.

Management

  • Use Azure Monitor and Log Analytics: Monitor your virtual network to detect and troubleshoot issues quickly. Use Log Analytics to collect, analyze, and visualize your network data.
  • Backup and Restore: Regularly back up your virtual network configuration and VMs to ensure that you can recover quickly in the event of a failure.
