Using baremetal and user level segregation, we can use systemd multi-instance to provide MariaDB as on demand PaaS, where every user gets their own configuration. This talk will show you what this looks like from a user and system maintainer perspective. With containers as all the rage, and the perceived default way of doing things, lets take a look at another approach of PaaS.

So with a few configuration changes from a default MariaDB install, let's show what a per user database instances looks like. Adding socket activation to mix and see "serverless" capability before it came fad with Kubernetes. On top of that, a brief look at abstract sockets that have been in MariaDB for while and what they could look like in a PaaS environment.
