Azure Regions

Understanding Regions is not as easy as one might initally assume. Understanding regions is crucial for a good cloud design and architecture.

Here is a nice Infrastructure Map. According to the azure global-infrastructure we have geography in which there are regions which is a set of data centers:

  • An Azure geography typically contains at least one or more regions, that preserves data residency and compliance boundaries.
  • An Azure region has a discrete pricing and service availability and is a set of data centers, deployed within a latency-defined perimeter and connected through a dedicated regional low-latency network.
  • Azure data centers are unique physical buildings located all over the globe that house a group of networked computer servers.

Aside from this there are multiple names for a region and location, logical and physical locations, different interpretations of geography and IP-Ranges are categorized in Service Tags.

We can filter all regions of a given geography e.g. Europe:

az account list-locations --query "[? contains(regionalDisplayName,'(Europe)')]" -o table

To get an overview of all locations we can run the following command:

The list-locations result also has "logical" instead of physical entries which seems to include staging regions and/or location categories.

Running this command we only get logical locations:
