Microsoft Azure has tons of data centers and region. At the time of writing this, Azure is made up of 24 regions with more, new regions announced coming soon. In fact, Microsoft Azure is bigger than both Amazon’s and Google’s cloud services combined!
Microsoft Azure also has a ton of features, however, not all features are available in every data center. The majority of features are, but some are not. To help determine which Azure features are supported in each region, Microsoft has a “Services by Region” page available. This page allows you to easily see which Azure features are available in which regions, and can really help in planning out what regions and data centers you’re going to deploy to in the Microsoft Azure cloud.
The Azure Services by Region page can be found here:
