I would love to understand your experiences. How do you detect issues? Are you using feature flags? Have you had any disasters? How do you deal with problems? What are the biggest pain points? Kubernetes? Etc?
What's there to know? You divert some orthogonalizable flow (orders,
accounts, widgets, etc.) to a parallel setup. The trick is orthogonalizable
because if something in the main flow depends on something in the test flow,
you're in for it.
