I just finished reading a couple of interesting, and somewhat related, blog posts which I think are worth sharing (apologies to anyone who has already seen them). One is from Jelastic and the other is from Michal Hrušecký.

I’ve written about MariaDB and the Jelastic cloud before (see MariaDB now available as a hosted database via Jelastic cloud platform).
