Principle
Reliability is part of the product
Users do not separate "the product" from "the platform that delivers it." Neither should you.
- 2025
There is a habit of treating reliability as something that lives outside the product — owned by infrastructure, measured by uptime, defended in postmortems. Users do not experience the system that way. To them, every silent failure, every retry that didn’t happen, every state that drifted, is the product.
Reliability is not a non-functional requirement. It is a feature.
