Virtual Network

A fundamental part of Azure. All services are connected to a VNet. Includes an IP address range and subnets. Belongs to a single region and a single subscription.

  • Resource Grouping - Group resources onto the same subnet to make it easier to keep an overview.
  • Address Allocation - More efficient to allocate addresses to resources on a smaller subnet.
  • Subnet Security - Use network security groups to secure individual subnets.

Subscriptions - A VNet belongs to just one subscription, but a subscription can have multiple VNets.

Regions - A VNet belongs to a single region. Every resource on the VNet must be in the same region too.
