The relationship between Microsoft Office 365 and Azure

This content is 9 years old. I don't routinely update old blog posts as they are only intended to represent a view at a particular point in time. Please be warned that the information here may be out of date.

At a recent partner event, Microsoft Partner Technical Specialist, Robert-Jan Gerrits, answered a question that many people ask: does Office 365 run on Azure?

The short answer is “no” – the Office 365 infrastructure is dedicated – i.e. it’s not a bunch of VMs running on Azure; however there is a slightly longer answer.

Office 365 uses Azure for:

  • Office 365 video (media)
  • Azure blob storage (storage)
  • Azure AD for identity (identity)
  • Power BI app (cloud services)
  • Access services (storage)

Over time, we can expect to see more and more Office 365 components using Azure services but, for now, Office 365 is (almost) a standalone environment.
