     真正的上线服务，要考虑的生命周期管理的问题：
     -- 上线就不能停 --
     配置文件级修补，代码级修补，升级，如何处理？
     load balancing如何扩展？
     内容级别的判活检测
     部署，备份，升级，回滚
     更细致的还有日志文件的配置（日志文件放哪，内容什么格式，保留多少）
     系统内存调优？（jvm内存使用，垃圾回收参数配置）
     最好给程序开点后面
     紧急情况用最快的办法看服务的状态
     紧急情况预案
     
     事先了解运维团队的监控需求
     密钥和密码管理
     如何进行跨可用区、数据中心容灾？
     灾难发生后的恢复过程，比如主备两个数据库状态已经不同步

     对服务器作配置变更
     移出机器、加入机器、更换机器的方案。实际情况，部署是少数，升级、扩容占多数

1. data plane和mgmt plane。data plane往往是性能关注的，mgmt plane往往不需要。
   软件设计在这里有分野
