I think it&#x27;s not so much &quot;open source is our future&quot; as it is &quot;if you can&#x27;t beat them, join them&quot;. I&#x27;m sure there are plenty of folks at Microsoft who realize that sticking with Windows in Cloud puts them at a competitive disadvantage vs eg Amazon or Google. There are things that _have to_ use Windows (Azure AD, MS SQL, Exchange, Sharepoint), but everything else is only harmed by it. So the litmus test is going to be whether they actually move their major backend systems to Linux in the coming 2-3 years. If they do not, all these Linux ports will remain second class citizens compared to Windows versions, with lower performance, fewer features, and more bugs. Which is probably why Microsoft is releasing them in the first place: if you want the real deal, come to papa.
