One thing that I’ve learned over the years is that the best way to improve your application over time is to have developers carry pagers. Certainly it can be a bit of a pain when your software catches fire on Friday afternoon, nobody will disagree there, but it means that you are forced to be in touch with the issues surrounding operating the stack in production.
OMG [insert new tech] is awesome!
Sure, it seems like a great piece of technology but how does it behave in production? Is it constanly crashing?
