Lets Review What are different resources that get created when we create a VM

• Create a new linux machine under a new resource group and look at resources created

  1. If you already have a network you can select one or azure will create one for you. This network will have one subnet
  2. Logs of the VM are stored in Storage Account
  3. When we create a vm we might require a public IP, so Azure public IP Address is also created
  4. NSG is Network security group which has rules to allow/deny network on specific ports of your vm
  5. A Network Interface (NIC) which is virtual gets associated with VM for providing network connectivity. IP address, NSG are applied to NIC.
  6. A Disk which acts as hard disk to your vm gets created.

• Create a new windows machine under a new resource group

• Now lets create a mapping between the options and the resources created
