Smartleaf runs out of high-quality third-party datacenters on hardware we buy, install and maintain ourselves, running Ruby on Rails and C++ and Oracle/Postgresql on Debian with borg backups. Is that close enough? We also deploy with Chef and an in-house application deployment system written in Perl, do monitoring with mon, and understand that a sysadmin is a subject matter expert. Hiring, too.
