Scaling the Sound: Fleet Management at Spotify
Talkat Platform Engineering Day 2025 - Europe · on Tuesday, 2025-04-01· at 10:40· Level 1 | Hall Entrance N10 | Room F·
summary
Spotify describes a move to a fleet-first approach that standardizes on a defined golden tech set, Backstage plugins and templates, and declarative infra so automation can perform org-wide maintenance. Fleet Shift runs containerized “shifts” as Kubernetes jobs to clone repos, transform files, open PRs and optionally automerge; Soundcheck measures certification. Results: Apollo upgrades drop from ~200 days to under 7, Fleet Shift authors 1.8M contributions with a 3:1 bot:human ratio, and 80% of fleet log4j updates complete in under 11 hours.
