Docker and related tech will eat its lunch.
Linux is killing Windows in the server space, and has been for years. As more software migrates to web stacks, the trend will continue to accelerate.
This isn’t about server space, this is client side. And the web stack “migration” is one of the funniest myths in computing today... and for the last 2 decades. Ever since the world ditched thin clients people, including Bill Gates at one point, have been insisting that the world will go back to it under a different name. Not happening. When push comes to shove local install works better, it’s faster, it’s more secure, and it’s less prone to lightning bolts.
