App Performance

Ask an SRE what "reliability" means and you'll get a pretty consistent answer. It means uptime, latency SLOs, error budgets, on-call rotations, and someone's pager going off during a dinner party. (I know, no one carries pagers any more. I’m just enjoying an anachronistic moment.) None of that is wrong. But it's incomplete, and that incompleteness may be hurting your users and your business.
