Core principles

Measure before cutting — rightsizing requires utilization data, not guesses

Tag everything — cannot optimize what cannot be attributed

Right-size before committing — buying reservations for wrong size locks in waste

Dev/staging should sleep — idle non-production is the largest hidden cost

Egress costs are silent killers — always put CDN in front of public content
