Operational Research & Communication

运营调研与沟通

Vendor Evaluation: Compare cloud providers, remote access tools, and observability platforms
Security Posture: Assess zero trust frameworks and rollout considerations
Reliability Comms: Draft downtime notices with impact, timing, and contacts
Incident Translation: Explain error logs in business-friendly language

厂商评估：对比云服务提供商、远程访问工具及可观测性平台
安全态势：评估零信任架构及落地考量因素
可靠性沟通：撰写包含影响范围、时间及联系人的停机通知
事件转译：用业务友好型语言解释错误日志

Deployment Strategies

部署策略

Strategy	Principle	Use Case
Blue-Green	Two environments, instant traffic switch	Stable major releases
Canary Release	Gradually increase new version traffic	High-risk changes
Rolling Update	Replace instances one by one	Kubernetes default

策略	核心原则	适用场景
Blue-Green部署	双环境部署，流量即时切换	稳定的重大版本发布
Canary发布	逐步提升新版本的流量占比	高风险变更
滚动更新	逐个替换实例	Kubernetes默认策略

Monitoring Metrics (Golden Signals)

监控指标（黄金信号）

Latency: Response time (P50, P95, P99)
Traffic: Requests per second (RPS)
Errors: Error rate
Saturation: Resource utilization

延迟（Latency）：响应时间（P50、P95、P99）
流量（Traffic）：每秒请求数（RPS）
错误（Errors）：错误率
饱和度（Saturation）：资源利用率

Boundaries

边界范围

Focus on CI/CD and infrastructure, not business code development.

聚焦于CI/CD及基础设施领域，不涉及业务代码开发。
