出一些改变。比如，微前端已经实现的部分，旧版应用就不应该再提供此服务，而是应该
将用户重定向到一个绝对

地址，让路由将用户重定向到正确的位置。
另一个需要解决的问题是要找到一种方法，能够让用户遇到错误时可以快速切换版本。我
们在推出新的微前端平台时使用的一种技术是在一段时间内同时维护三个版本：旧版本、
混合版本（原有应用和微前端共存的兼容版本）和微前端版本。通过这种方式，在日常服
务中，我们可以一直维护混合版本和微前端版本，而在遇到无法快速修复问题的极端情况
时，可以全量切换到旧版本。

用户和公司创造即时价值
这种同时维护几个版本的配置会持续若干月，直到完成所有微前端的开发和改造。在这一
过程中，我们可以根据业务诉求循序渐进地改进平台。
在某些情况下，这看起来像是一种过度设计的解决方案，但是，我们的业务场景不允许停
止线上服务，所以必须为用户和公司找到一个折中策略。绞杀者模式可以让我们分析公司
能够承担多大的风险，并根据分析结果设计出合适的实现方案。

可观察性
在一个成功的微前端架构中，需要着重考虑的最后一个因素是可观察性。可观察性反馈闭
