Ask HN: If WinServer2019 was made free to use tomorrow,would you start using it
Would you be more likely to adopt it if Microsoft open-sourced it? (I know very little chance of that)
In either case Microsoft could make money on support, and consulting services.
I think more competition on the server side, than various flavours of Linux and some flavours of UNIX would be healthy.
For a time I worked in Windows only enterprises and I had little to do with administering any of the servers, but code got deployed to them and I never had any issues with the parts of the server I used.
I would think that there are some workloads and tasks that might make more sense to run on a Windows Server vs a Linux one but I am not sure what (aside from legacy Windows only applications)
