Resources Required for VM

When we create a VM, it lives within a particular subscription, which has at least 1 resource group

• The VM, at minimum has an OS managed disk, which is in itself an Azure resource

  • There are also ephemeral disks where it uses cache or temporary disk for that OS, but if you deallocate or stop that VM then you lose that OS state

  • We may also have additional Data disks

    • You pay for the VM along with those disk

• The VM requires connectivity via a vNet, which has subnets

  • We attach a virtual NIC to the VM, which connects to a subnet in a vNet.

  • You don't pay for the NIC or subnet, but you do pay for egress

    • In the future you may be charged for AZ to AZ movement

• You might have an optional public IP, another self contained resource, that is binded to the NIC

• You might have a NSG as well that is attached to the subnet (preferred) or the NIC directly
