Meta 部署安全实践：持续变更安全的健康检查
原标题：Making Deployments Safe at Meta: Health Checks for Continuous Change-Safety
AI 摘要
Meta 在 arXiv 发表论文，介绍其部署时健康检查基础设施 Service Health Checker (SHC)，用于在数千个异构服务的持续部署中平衡发布速度与可靠性。SHC 通过模板化指标查询、阈值和工作流谓词，与分层和分阶段发布集成，在回归时自动回滚。论文还讨论了规模化运营中出现的噪声、告警疲劳、漂移和未覆盖回归等问题，以及应对措施和未来方向，包括 AI 辅助健康检查调优。

Making Deployments Safe at Meta: Health Checks for Continuous Change-Safety Abstract Continuous deployment to large-scale production systems creates a tension between release velocity and reliability: every change is a potential reliability incident, yet every delay is a missed opportunity. This paper describes the deployment-time health-check infrastructure that Meta uses to mediate this tension across thousands of heterogeneous services. We summarize the architecture of the Service Health Che
