It’s 2:00 a.m. A pager goes off in a suburban home. A bleary-eyed woman makes her way to a terminal hooked up to a 1200-baud modem. She works until 6:00 a.m. to fix the system problem remotely, this time just having to edit and restart a data load job, then monitoring the log to ensure that things are fixed.
If you’re thinking that’s so 1980s, you’re right. However, substitute “smartphone” for “pager” and “laptop with Wi-Fi” for “1200-baud terminal,” and you’re not that far off from how things are done today on the cloud.
