What about a backend?

100+ datacentersTop 3 networks in the world2x AWS, 6x Google DC RegionsG Series Largest VM in World32 cores, 448GB Ram, SSD

Operational

Announced* Operated by 21Vianet

24Azure compute regions open todayMore than AWS and Google Cloud combined

Infrastructure designed for ScaleDatacenters recently added in Canada, China, and India

And you get all the goodness shown in the previous slides across the WWBuild 2015

Extremely powerfulYou can do almost anything your backend would ever need to do with Azure. Data storage, authentication/authorization, push notifications, custom APIs, blob storage, etc.FlexibleNeed something lightweight? Azure is there.Need something robust and powerful? Azure is there.C# clientsIm a frontend developer, I care a lot about how easy this makes MY job (selfish)Many C# clients are written by Java developers, etc.Easy to use C# clientAbstracts away much of pain of using a RESTful APIC# FeaturesAsync / Await / TPLUses C# idiomsProperties, Fluent APISeems obvious, but not always true (first class citizen)
