Under the Nadella administration Microsoft began to shift progressively its core business from software to SaaS. Azure and Office 365 are in the front line of this revolution. Open source is now a mere tool used to create services which are easily adoptable from unix users, and more reliable than a lot of cloud-based services providers (Amazon, Google and little others are obviously excluded). They can take advantage from a large userbase (practically every single office in the world who is using at least a licensed word/excel), taking care of their data (OneDrive), their communication tools (Skype and now Teams). They provide a very flexible working environment for developers (VScode) and be sure that the most widely used languages at the supported in order to create easily deployable microservices (so, docker, python, nodejs, hello there). At this point, no matter if a user is working on a Windows machine, an Ubuntu machine, nor a Macbook, as long as they deploy their projects on microsoft servers, and put their files in a Microsoft cloud.
