<div id="magicdomid753" class="ace-line gutter-noauthor text-align-type-justify pap-stylesheet-name-normal emptyGutter"><span class="font-family:等线">在开始之前，我们先来讨论一个问题——是自建容器服务还是托管到云容器服务？</span></div>
<div id="magicdomid754" class="ace-line gutter-noauthor text-align-type-justify pap-stylesheet-name-normal emptyGutter"><span class="font-family:等线">这里笔者建议大家托管到云容器服务。对于中小团队来说，很多情况下，团队中的运维人员是缺失的，或者运维人员的水平非常有限——大部分比网吧的网管就好那么一点，从成本、安全（云端产品往往提供了一些解决方案，比如权限控制、灾备、高可用、数据加密等）、扩展性的角度，使用云容器服务更加靠谱和省事，而且是可以直接开箱即用的（可以直接跳过自建的初始化时间）。而且随着生产力的继续发展，人的成本一定会越来越高于机器的成本，而且目前已经是远远高于机器的成本了。因此，如何选择，大家是否心中有数了呢？</span></div>
