Erase Your Darlings

The biggest enemy of Resiliance in systems is “works of art.”

Components of the system that have been hand-crafted over the years that, if failed, would be impossible to reproduce in a predictable time.

Works of art fly in the face of Continuous Testing, lowers one’s ability to have Low Risk Releases, and makes it very difficult to have strong Psychological Safety while Developing Good Explanations.

Instead, practice Immutable Infrastructure (but to an even greater degree). Seek out things that cause Configuration Drift and root them out of the system. Culturally, this also makes state Opt-In vs Opt-Out., better than Immutable Infrastructure.
