Yeah it bugs me too. The line gets even blurrier now that one of the latest models is to integrate devops with the dev team. And put developers on call to handle system generated alarms. That used to be the job of what we called a sysadmin, but as part of everything being “cloud” now, they figured they could save some money and make developers do IT work as well, call it devops, and then squeeze out a bunch of related IT roles.
