export default monitor;通过本节前端部署和运维教程的学习,你已经掌握:
A: 建议顺序:代码检查→自动化测试→自动化构建→自动化部署→监控告警。先保证代码质量,再实现自动化部署。
A: 容器化的性能开销很小(通常<5%),但带来的环境一致性和部署便利性收益远大于性能开销。
A: 根据项目规模选择:小项目使用简单的错误监控,大项目建立完整的性能监控、错误追踪、用户行为分析体系。
A: 考虑因素:成本、性能、服务质量、技术支持、数据安全。国内项目优先考虑阿里云、腾讯云,国际项目考虑AWS、Azure。
A: 代码备份依赖Git,构建产物备份到云存储,数据库定期备份,配置文件版本化管理。制定灾难恢复预案。
