How Netflix Saves Millions of Dollars With Swabbie
summary
Swabbie is a Spinnaker service (Spring Boot, Kotlin) that automatically marks and safely deletes unused cloud resources using a rules engine, locks and work queues, and Redis-backed state and metrics. It enforces exclusion policies, schedules and per-cycle limits to limit blast radius, supports AMIs, auto scaling groups and EBS snapshots, and integrates with cloud drivers and Echo for notifications. At Netflix it reduced ~300,000 images to ~100,000 in days, claiming millions of dollars saved.
