I’m unaware if there’s caps, the pricing just seemed opaque to me due to poor monitoring tools.

Security wise, Ubuntu LTS with unattended upgrades and livepatch is likely better than 99% of public facing servers.

Huh, i'll have to look into that. I'm not aware of unattended upgrades. Though i still value not risking a messed up config leaking data by way of ssh access, or something.

If you install a current version of Ubuntu it uses perfectly sane defaults for SSH. If you go the step further and disable password authentication entirely and only use keys you’ll be very secure.

I fully understand the preference of a serverless platform of course, especially if you’re more of a programmer and less sysadmin.
