Authentication to Azure can be accomplished via management certificates, or via Azure Active Directory. Once we've authenticated to Azure, we'll next select the Azure subscription in which our Azure Virtual Network is provisioned.

Many organizations have more than one Azure subscription for different release stages dev, test, productionapplications or business units. After selecting the appropriate Azure subscription, we'll need to grab the subscription ID and the management certificate thumbprint we used when authenticating to Azure. Some organizations may have more than one Azure Virtual Network provisioned within their Azure subscription.
