## 29.6.6 最佳实践

### 1\. 安全性

• 使用環境變數儲存敏感資訊
• 實現請求認證和授權
• 限制程式碼執行許可權
• 輸入驗證和清理

2. 可擴充套件性

• 使用非同步處理提高併發
• 實現快取機制減少重複計算
• 支援水平擴充套件
• 使用訊息佇列處理非同步任務

3. 可靠性

• 實現重試機制
• 使用斷路器模式
• 健康檢查和自動恢復
• 資料持久化和備份

4. 可觀測性

• 完善的日誌記錄
• 效能監控和告警
• 分散式追蹤
• 指標收集和分析

透過合理的整合和部署，我們可以將程式設計 Agent 部署到生產環境，為使用者提供穩定、高效的程式設計輔助服務。
