MSDN subscriptions for your developers get you cheaper Azure VMs
We know Visual Studio Pro with MSDN gets you unlimited Windows Server (including Hyper-V for virtualisation) and unlimited SQL. This is a way of licensing Microsoft software in your on premises test and development environments. You can now bring your own MSDN licences with you to Azure. This way the Microsoft software in your Windows and SQL VMs on Azure is already paid for and you pay the equivalent of Linux rates for Windows and SQL VMs on Azure.
