Best Practices

最佳实践

Serverless Design Principles

无服务器设计原则

  1. Stateless functions - Store state in DynamoDB, S3, or ElastiCache
  2. Idempotency - Handle retries gracefully, use unique request IDs
  3. Cold start optimization - Use provisioned concurrency for critical paths, optimize package size
  4. Timeout management - Set appropriate timeouts, use Step Functions for long processes
  5. Error handling - Implement retry logic, dead letter queues, exponential backoff
  1. 无状态函数 - 在DynamoDB、S3或ElastiCache中存储状态
  2. 幂等性 - 优雅处理重试，使用唯一请求ID
  3. 冷启动优化 - 关键路径使用预置并发，优化包大小
  4. 超时管理 - 设置合理超时，长流程使用Step Functions
  5. 错误处理 - 实现重试逻辑、死信队列、指数退避

Cost Optimization

成本优化

  1. Right-sizing - Start small, monitor metrics, scale based on actual usage
  2. Reserved capacity - Use Savings Plans or Reserved Instances for predictable workloads
  3. S3 lifecycle policies - Transition to cheaper storage tiers (IA, Glacier)
  4. Lambda memory optimization - Test different memory settings for cost/performance balance
  5. CloudWatch log retention - Set appropriate retention periods (7-30 days for most)
  6. NAT Gateway alternatives - Use VPC endpoints, consider single NAT in dev environments
  1. 资源合理配置 - 从小规模开始，监控指标，根据实际使用扩缩容
  2. 预留容量 - 可预测工作负载使用Savings Plans或预留实例
  3. S3生命周期策略 - 转换到低成本存储层（IA、Glacier）
  4. Lambda内存优化 - 测试不同内存配置以平衡成本与性能
  5. CloudWatch日志保留 - 设置合理保留期（多数场景7-30天）
  6. NAT Gateway替代方案 - 使用VPC端点，开发环境考虑单NAT

Security Hardening

安全加固

  1. Principle of least privilege - IAM roles with minimal permissions
  2. Encryption everywhere - At rest (KMS) and in transit (TLS/SSL)
  3. Network isolation - Private subnets, security groups, NACLs
  4. Secrets management - Use Secrets Manager or Parameter Store, never hardcode
  5. API protection - WAF rules, rate limiting, API keys, OAuth2
  6. Audit logging - CloudTrail for API calls, VPC Flow Logs for network traffic
  1. 最小权限原则 - 权限最小化的IAM角色
  2. 全面加密 - 静态加密（KMS）与传输加密（TLS/SSL）
  3. 网络隔离 - 私有子网、安全组、NACL
  4. 密钥管理 - 使用Secrets Manager或Parameter Store，绝不硬编码
  5. API保护 - WAF规则、速率限制、API密钥、OAuth2
  6. 审计日志 - 用于API调用的CloudTrail、用于网络流量的VPC流日志

Scalability Design

可扩展性设计

  1. Horizontal over vertical - Scale out with more small instances vs. larger instances
  2. Database sharding - Partition data by tenant, geography, or time
  3. Read replicas - Offload read traffic from primary database
  4. Caching layers - CloudFront (edge), ElastiCache (application), DAX (DynamoDB)
  5. Async processing - Use queues (SQS) for non-critical operations
  6. Auto-scaling policies - Target tracking (CPU, requests) vs. step scaling
  1. 水平扩缩优先 - 增加小实例而非大型实例
  2. 数据库分片 - 按租户、地理位置或时间分区数据
  3. 只读副本 - 分流主数据库的读流量
  4. 缓存层 - CloudFront（边缘）、ElastiCache（应用）、DAX（DynamoDB）
  5. 异步处理 - 非关键操作使用队列（SQS）
  6. 自动扩缩容策略 - 目标追踪（CPU、请求数）vs 阶梯式扩缩容

DevOps & Reliability

DevOps与可靠性

  1. Infrastructure as Code - Version control, peer review, automated testing
  2. Blue/Green deployments - Zero-downtime releases, instant rollback
  3. Canary releases - Test new versions with small traffic percentage
  4. Health checks - Application-level health endpoints, graceful degradation
  5. Chaos engineering - Test failure scenarios, validate recovery procedures
  6. Monitoring & alerting - Set up CloudWatch alarms for critical metrics
  1. 基础设施即代码 - 版本控制、代码评审、自动化测试
  2. 蓝绿部署 - 零停机发布、即时回滚
  3. 金丝雀发布 - 小流量比例测试新版本
  4. 健康检查 - 应用级健康端点、优雅降级
  5. 混沌工程 - 测试故障场景、验证恢复流程
  6. 监控与告警 - 为关键指标设置CloudWatch告警

Common Pitfalls to Avoid

常见误区规避

Technical Debt

技术债务

  • Over-engineering early - Don't build for 10M users when you have 100
  • Under-monitoring - Set up basic monitoring from day one
  • Ignoring costs - Enable Cost Explorer and billing alerts immediately
  • Single region dependency - Plan for multi-region from start
  • 早期过度设计 - 不要在只有100用户时就为1000万用户做架构
  • 监控不足 - 从第一天就搭建基础监控
  • 忽视成本 - 立即启用Cost Explorer与账单告警
  • 单区域依赖 - 从一开始就规划多区域

Security Mistakes

安全错误

  • Public S3 buckets - Use bucket policies, block public access
  • Overly permissive IAM - Avoid "*" permissions, use specific resources
  • Hardcoded credentials - Use IAM roles, Secrets Manager
  • Unencrypted data - Enable encryption by default
  • 公开S3存储桶 - 使用存储桶策略、阻止公共访问
  • 过度宽松的IAM权限 - 避免"*"权限，使用特定资源权限
  • 硬编码凭证 - 使用IAM角色、Secrets Manager
  • 未加密数据 - 默认启用加密

Performance Issues

性能问题

  • No caching - Add CloudFront, ElastiCache early
  • Inefficient queries - Use indexes, avoid scans in DynamoDB
  • Large Lambda packages - Use layers, minimize dependencies
  • N+1 queries - Implement DataLoader pattern, batch operations

  • 低效查询 - 使用索引，避免DynamoDB全表扫描
  • 过大Lambda包 - 使用层、最小化依赖
  • N+1查询 - 实现DataLoader模式、批量操作

Cost Surprises

成本意外

  • Undeleted resources - Tag everything, review regularly
  • Data transfer costs - Keep traffic within same AZ/region when possible
