- licensing costs are probably the same. If the cost of an additional Windows Server license is an argument, something else is going on.
- recently having dealt with MS Enterprise support on Linux, it was an horrendous experience I can nobody recommend
- an Enterprise with need for SQL Server without Windows Server support engineers?
- did we see independent performance tests published? A quick search I found these http://www.fhtino.it/blog/showpost.aspx?id=6790c78accb84f9c9..., seemingly not a convincing argument.
IMHO the whole story stinks and none of the arguments mentioned by Microsoft are valid. Probably it is all about winning hearts and minds.
SQL Server on Docker images for Devs is great as these are free of licensing costs (I guess).
