System Administration
Buying or renting a server is only the start of owning one, like a puppy they need to be fed and groomed to keep them running in tip top condition (and sometimes they may have an accident and make a mess of themselves). For a server, this means making sure updates are installed in a timely manner, making sure backups are done regularly, checking the system health (both hardware (sensors and SMART etc.) and OS (load, users, disk space etc), checking logs daily and checking for intrusion and malware.
