Getting power right in a DC takes a ton of preventative maintenance. (doing black building tests, make sure there are working load tests which occur frequently, managing UPS battery health etc).
- spenczar5 5y agoYes, it's hard work... but it's work AWS should be great at. Like, really great at. I used to work at AWS. The most worked-up I ever saw Charlie Bell (the de facto head of AWS engineering) was in the weekly operations meeting, going over a postmortem which described a near-miss as several generators failed to start properly in a power interruption. In this meeting - with nearly 1,000 participants! - Charlie got increasingly irate about the fact that this had happened. For the next few weeks, details of some sort of flushing subsystem for backup generators was an every-time topic. Sadly, Charlie left AWS and now works at Microsoft. I can't help but wonder what that operations meeting is like now without him.
