Rightsize Ruthlessly, Scale Gracefully
Use weeks of CPU, memory, and I/O metrics to select smaller instance families, storage classes, and database sizes. Schedule non-production resources to sleep outside business hours. Pilot changes with canaries, monitor performance closely, and invite engineers to propose rightsizing candidates during weekly reviews.
Rightsize Ruthlessly, Scale Gracefully
Adopt serverless and event-driven designs to eliminate idle. Turn ephemeral environments on per pull request and off after merge. Batch jobs can run on-demand, not always-on instances. Ask your team: which services truly need to be 24/7, and which can scale to zero safely?
