#Simple script to deploy VM based on snapshot in Azure
#Will auto-provision and name resources based on contract name passed in
#
# You will need to fill in the subscription id! You can get this by just running the Login-AzureRmAccount and inspecting the response or by logging into the Azure portal in a web browser
