这种架构的痛点在于使用
Redux
管理全局状态，以便在微前端之间共享应用的状态。如前
所述，每个微前端都应该是完全独立的，但在
Holocron
中并非如此
，需要自定义事件用于
微前端之间的通信。虽然这不是
React
应用中最常用的通信技术
，但它确实离完全接受微
前端原则又近了一步。由于
Holocron
模块可以存储在任何地方
，不需要从虚拟的
CDN
中
获取，因此虚拟机、对象存储或容器也可能是合适的解决方案。
OpenComponents
是另一个用于服务器端横向拆分架构的微前端框架
。该框架提供了几个
开箱即用的功能，包括通过运行时代理预热
CDN
，微前端注册表和简化开发体验的工具
。
每个微前端都被封装在一个计算层内，该计算层与其他层完全隔离。这种方法使每个团队
能够专注于所负责领域的实现，而不用考虑整个应用。此外，每个微前端都有一套实用工
具，提供观察和监控能力以及数据概览页。为了管理一天中特定时间的突发流量（比如来
自餐厅预订餐桌的持续流量），每次创建新的微前端或对现有的微前端进行更改时，都会
将正在使用的
CDN
流量进行清理或者刷新预热（图

有趣的是，由于
OpenComponents
不仅允许服务器端渲染，而且允许客户端渲染，因此
你可以为每个用例选择合适的技术。比如，当
