“Documentation! Hey, look at that.”
Lemme start this off by saying this is probably irrelevant to you. (It’s irrelevant to me, too.)
If you’re strapped for time, just skip past this blog post.

AWS Aurora MySQL is Amazon’s flavor of MySQL with their own unique performance and reliability improvements. I’ve never used it, and I don’t see myself using it anytime soon because I just don’t need it. The database back end for the BrentOzar.com blog is MySQL, but I use a managed WordPress hosting partner, so Aurora MySQL is irrelevant there too.
