应用程序保持运行的同时将其重新绑定到不同的源上去

。在许多场景下该
功能都非常得强大。
例如，当你的边缘（
edge
）应用升级到云端时，可以将
其动态绑定到基于边缘的服务或基于云的服务，以适应环境的变化。

小结
本章提供了关于
Dapr
的概要总览，这是一种语言无关的编程模型，该模型使
用边车为应用代码提供了微服务的构件（包括绑定、状态管理、可靠消息传
递和
actor
等能力），同时不要求应用代码包含任何
Dapr
的特定库或
SDK
。
Dapr
的主要目标是从开发人员那里抽象走了基础设施的细节。通过
Dapr
的
构件，应用代码与底层基础设施完全隔离，从而允许在不同平台上部署时配
置以及重新配置应用，而无需更改应用的代码。这是一项强大的功能，让诸
如边缘（
edge
）和多云应用之类的方案成为可能。
我们希望你对
Dapr
感兴趣。在本书的其余部分中，我们将展开介绍
Dapr
所
有的组件，并涵盖
Dapr
的各种应用场景。我们还将介绍如何以不同的方式扩
展
Dapr
。我们希望你加入社区，以帮助
Dapr
成为每个人都可以使用的简单、
高效并且强大的分布式编程模型！
