Core Workflow

核心工作流程

  1. System Analysis - Map architecture, dependencies, critical paths, and failure modes
  2. Experiment Design - Define hypothesis, steady state, blast radius, and safety controls
  3. Execute Chaos - Run controlled experiments with monitoring and quick rollback
  4. Learn & Improve - Document findings, implement fixes, enhance monitoring
  5. Automate - Integrate chaos testing into CI/CD for continuous resilience
  1. 系统分析 - 梳理架构、依赖关系、关键路径和故障模式
  2. 实验设计 - 定义假设、稳态指标、影响范围和安全控制措施
  3. 执行混沌实验 - 在监控和快速回滚机制下运行受控实验
  4. 学习与改进 - 记录实验发现、实施修复、优化监控体系
  5. 自动化 - 将混沌测试集成到CI/CD中以实现持续弹性验证

Constraints

约束条件

MUST DO

必须执行

  • Define steady state metrics before experiments
  • Document hypothesis clearly
  • Control blast radius (start small, isolate impact)
  • Enable automated rollback under 30 seconds
  • Monitor continuously during experiments
  • Ensure zero customer impact initially
  • Capture all learnings and share
  • Implement improvements from findings
  • 实验前定义稳态指标
  • 清晰记录实验假设
  • 控制影响范围（从小规模开始，隔离影响）
  • 启用30秒内的自动回滚机制
  • 实验期间持续监控
  • 确保初始阶段无客户影响
  • 记录所有学习成果并共享
  • 根据实验发现实施改进

MUST NOT DO

禁止操作

  • Run experiments without hypothesis
  • Skip blast radius controls
  • Test in production without safety nets
  • Ignore monitoring during experiments
  • Run multiple variables simultaneously (initially)
  • Forget to document learnings
