Azure Virtual Network Manager
In this post, I will guide you through creating an Azure Virtual Network Manager preview (VNM) and describe what the service can do for you. The service is still in preview when writing this post, so please do not deploy any of this into your production environment.
VNM will enable central management of connectivity and security policies across regions and subscriptions. What this actually means will be shown in the guide below, but it does bring something new to the table. The VNM adds yet another rule set to the security stack. These rules will override any Network Security Group (NSG) rules you might have already created. I am not really sure I like yet another ruleset. We already have an Azure Firewall and Network Security Group, so adding one more to the mix will make troubleshooting a bit harder.
