OAM
应用模型由一个兼容
OAM
的控制平面来管理。在
Kubernetes
上，
OAM
应用模型通常由对应
operator
管理的几个自定义资源组成。
Dapr
可以
很好的与此类控制平面一起工作，因为后者通常都支持
Kubernetes pod
注解
或者类似的机制。有关支持
Dapr
的更多细节，请参阅你所选择的控制平面的
文档。
在收尾本章的这一部分之前，我们来看一个经常被问到的问题。
6.3.5 Dapr
和服务网格
我们经常会被问到
Dapr
和现有的服务网格解决方案（例如，
Istio
、
Linkerd
或者
Consul
）之间有什么区别。
Dapr
和服务网格确实有一些相似之处。因为它们都使用边车架构，而边车最
初是由服务网格普及的，所以许多人对
Dapr
的第一反应就是这是否是另一个
服务网格的竞争者。另外，随着
Dapr
的发展，
Dapr
也开始提供与网络更相
关但同时仍然是应用关注的功能，例如，
TLS
双向认证。
Dapr
与服务网格最主要的区别在于它们工作在不同的层次上。服务网格管理
服务之间的网络流量，因此它们是工作在基础设施层的。另外，
Dapr
为应用
提供了常见的构建模块，例如应用的状态管理，因此
Dapr
是工作在应用层的。
“网络网格”可能会是服务网格更好的名字，然后我们就可以将
Dapr
称之为
服务网格了。但是，由于“服务网格”的名字已经被用了，因此有的时候我
们将
Dapr
称之为”应用网格”，以便与服务网格技术区别开。
由于
Dapr
工作在不同的层上，解决的是完全不同的问题域， ...
