Full-Link Multi-Version Deployment in Testing Environments: Architecture and Practices

Vivo’s full‑link multi‑version deployment framework lets a complete microservice system be launched once while concurrently running multiple service versions in isolated baseline and on‑demand feature environments, using custom traffic‑coloring headers, tag propagation across HTTP/Dubbo/MQ, dynamic routing, and distributed tracing to reduce resource waste, accelerate hot‑fix testing, and pave the way for future data‑level isolation and production‑grade A/B experiments.

Implementing a Coloring Environment for Test Environment Stability

DeWu solved chronic test‑environment instability by evolving from isolated ECS machines to container clusters and finally to a traffic‑tagging “coloring” environment, where an x‑infr‑flowtype header routes requests to dedicated coloring nodes, achieving over 95% demand coverage, reduced conflict, lower costs, and a roadmap toward production gray‑release.
