The easiest thing I can fully automate

Full automation in DevOps means more than just automated deployments—it requires fast rollbacks, proactive communication, and processes that work under pressure. A 30-minute CI pipeline might be acceptable for releases but fails during outages when quick rollbacks to trusted versions are critical. Effective automation guides attention where it matters most, whether managing 4000 EC2 instances or 3 containers. The principles remain the same regardless of scale, though smaller environments allow faster iteration.
