The Stop That Could Not Travel
Lena runs the night shift beside a metal press. A sensor watches the space in front of the blade. She wants the machine to stop if a hand or a loose glove comes too close, and she wants that stop at once. She also wants a record of the week, so the morning crew can see which press is starting to drift. Those two wants are not the same job.
Cloud computing keeps the heavy work in large data centers. The shop uses storage and computing power there, and a person with access can open the reports from somewhere else. That is a good home for the weekly record and a poor home for the stop. A sensor reading would have to travel out, wait, and travel back. People call that wait latency. On this floor she cannot afford it.
