For a long time, since the beginning of Microsoft Azure, the most granular control you could have for choosing what servers / hardware to host a workload on has been the Azure Region. Each Azure Region is made up of at least 2 or 3 datacenters, but you didn’t have control over which data center was used or how replication was really controlled amongst the datacenters in a particular region. However, now Microsoft Azure has the ability to use Availability Zones to increase the resiliency and high availability of services hosted in a single Azure Region. These Availability Zones now offer a more granular control over hosting workloads in Azure beyond just choosing the less granular Azure Region to host in. Read More
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.
