Design and High‑Availability Practices of Bilibili's Video Submission System
Bilibili’s video submission platform uses a layered micro‑service architecture with a DAG‑based scheduler, extensive observability, and HA tactics such as sharding, 64‑bit ID migration, full‑link stress tests, chaos engineering, and multi‑active data‑center deployment, while tooling like trace correlation and automated alerts ensures stability and guides future hybrid‑cloud migration.
