Prodspec & Annealing: Intent Based Deployment
summary
Google moves most production to Prodspec & Annealing, an intent-first deployment stack started in 2015 for Gmail and now used across many services, claiming continuous automation replaces brittle per-service workflows. It enforces a consistent intent schema, generates that intent via a generation pipeline rather than hand-editing, and actuates changes with Select-Update-Validate to choose which clusters update, apply changes, and run validations. The result reduces configuration combinatorics, makes turn‑up workflows obsolete, and scales reliably at Google scale.
