It seems like the benefits of cloud infrastructure have normalized vendor lock-in.

I’ve never used Aurora because I don’t want to code anything to the idiosyncrasies of AWS (or any other cloud provider).

Aurora has compatibility layers and you interact with it as with normal MySQL, MariaDB or PgSQL. Of course there are some underlying differences, but the code and most of the tooling stay the same.
