Visual Studio (formerly MSDN) subscriptions come with purpose-specific (for software development and/or testing, depending on the subscription) licenses for lots of things (exactly what also depends on the tier, IIRC).

The usage constraints are mostly social/legal rather than technical, of course.

Visual Studio subscription is effectively $200/yr if you use Azure at all. It's $800/yr, but you get a $50/month Azure credit. It's not hard to use $50/month worth of Azure stuff.
