Azure is built for Windows, I hope it works well. However, I'm sorry... there's no way you're going to convince me of Windows as a "stack" is more reliable and robust, or even as scalable (in concurrent users and cost) than another stack like GoLang, Node, Python, Elixir... nope. Not going to agree with that man, I've been around much too long to see bullshit issues with Windows/IIS take town a whole operation based on SIMPLE issues -- hell IIS alone is a reason not to choose Microsoft as a stack, it's a DOG WITH FLEAS.
