@nikitonsky what filesystem do you use and which OS? How about package management, security patches, backups and process monitoring?

MySQL is probably runnng somewhere, over a socket or TCP on the same host? Works fine out of the box without any tuning.

Reverse proxies, configuration languages, etc.

Self-hosting definitely has its benefits, but for someone who just wants to write a blog post both options seem pretty inaccessible to me.

Better the devil you know.
