Azure Networking Basics

Azure virtual networks provide the key capabilities for resources to communicate with each other:

  • Communicate between Azure resources
  • Communicate with on-premises resources
  • Internet connectivity
  • Isolation and segmentation
  • Filter network traffic
  • Route network traffic
  • Connect multiple virtual networks

A virtual network is composed of many different components including, but not limited to, network interfaces, load balancers, subnets, network security groups, and public IP addresses.
