Oracle cloud may be better than azure at the lowest levels.
My prediction is this is part of why MS will buy Oracle.
Just my crazy prediction.
HN is not a representative sample of industry. Postgresql and Go are, of course, well-used, but Java and MySQL / Oracle are still absolutely massive.
Oracle, Java, C#, MS SQL might not be flashy in tech startups and on HN, but they are absolutely dominant in the wild.
