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.

Observability: Concepts, Challenges, and Didi’s Implementation

The article explains observability as the ability to infer any system state from external data, contrasts it with traditional monitoring, outlines challenges of high‑dimensional, high‑cardinality data and storage costs, and describes Didi’s hybrid MTL architecture that separates low‑ and high‑cardinality logs and metrics while linking them via TraceIDs to provide detailed, cost‑effective insight and streamlined debugging.

Effective Service Governance for Serverless: Challenges and Solutions

Effective serverless governance requires comprehensive observability, traffic management, and service registration built on Kubernetes, using either a mesh sidecar with Istio or an embedded SDK, to simplify complex operational tasks such as discovery, fault tolerance, gray releases, and metric correlation for large‑scale function deployments.
