If DevOps Is Culture, Why Does Everyone Only Talk About Tools?
summary
Shows how concrete DevOps practices and tooling produce measurable cultural change: automating deployments reduced manual deploy time from ~4 hours to ~20 minutes and cut failing deploys from ~100% to 3–5%, with daily production incidents dropping from ~10 to ~1. Recommends setting minimal test coverage (10–20%), enforcing max build and PR times, using rollbacks to previous container images and circuit breakers, and applying the theory of constraints to address bottlenecks before expensive rewrites.
