A major part of our lives is working safely with production - yet few organizations today are designing production to enable higher quality and end to end verification of the code we write and deploy. In this talk, we build on the foundation of great microservice architectures to include the first class design of testability as one of the most important artifacts that high velocity and high-quality teams should consider. In particular, we’ll explore what it’s like to build quality software with no development, QA, or staging environments. We'll include a deep dive into “verification in production” and what it really takes to build software that can safely be tested continuously in production. Let’s build developer happiness by *knowing* production is correct.
