Everythng that&#x27;s repetitious and error-prone: Manual migrations of old physical servers, disaster-recovery, managing legacy infrastructure. Luckily, most of these have been obviated by the cloud, thank god. I became a sysadmin to work on interesting projects, not to endlessly reset AD user credentials. Granted there is a level of repetition in any job, but when the process becomes to the job, it&#x27;s time to automate.
