Through installation, we saw no real server changes on the surface. We could choose to install Open SSH, DNS, LAMP, Mail, Print, SAMBA, Tomcat, and/or virtual machine hosts or add a Postgre database. Or our own manual package selection from the installation menu. We tried various combinations in several instances. Oddly, Canonical still packages MySQL as its default LAMP database, where many in the industry have gone to MariaDB, a fork of MySQL.
