What's "Azure web services api"?
The new announcement was for the App Service, which consists of four corners,
- Web Apps - what was Azure Web Sites
- Mobile Apps - what was Azure Mobile Services Zumo
- Logic Apps - snap together services from other folks, and write code to branch and decide how those are called.
- API Apps - allows you to write the things that all of the above use, or just expose apis in general, in a managed way, which can including billing on api use.
And none of these will be limited to asp.net. Want to use node for your web app? Sure. Java for your mobile app? Sure. Your api written in python? Sure.
