Cloud processes designed to protect your system may eat it alive
"Many of us are customers of Amazon without knowing it." Good point, Tom. The cloud providers still don't know how to get a circuit breaker into an automated process gone awry. Amazon's Easter weekend shutdown four years ago was triggered by human error, when an operations person unplugged a trunk network, then replugged it into a backup network. That made all the data sets visible on that trunk line disappear, which triggered a "remirroring storm" as the cloud software tried to make up for the lost data by creating new sets. While that was going on, everything else pretty much ground to a halt--for 2-3 days.
