"Oracle first, SQL Server second and AWS third"? I can't believe I'm hearing this. Where's DB2? And I guess that's not counting all the people who are using Postgres, Maria, MySQL, or whatever and not having to pay money to anyone, except for hardware. That Oracle - and IBM, for that matter - might have capabilities that are far ahead of anything either Amazon or open-source software can provide, though, is quite possible, but not everyone who needs a database needs those capabilities.
