Activity 1: Lets create a virtual network using ARM Template

• Manual steps:
• Create a resource group
• Inputs:
  • Location
  • Resource Group
  • Name of Vnet
  • address space of virtual network
  • subnets
• Lets try to write an ARM Template for this
• Create the basic skeleton with only required fields Refer Here
• For creating resources we would be using template reference Refer Here
• For virtual network Refer Here
• Refer Here for the changes done.
• Now create a resource group, as we are going to do resource group deployment
• Now create a custom template deployment
