举个相反的例子，有状态服务接口将倾向于通过将使用者与特定提供者实例关联来增加使用者和提供者间的耦合。

运行时生命周期：使用者知道(因而依赖于)运行时状态或服务提供者的准备情况，这就表明存在紧密耦合行为。
Runtime life cycle: the consumer's awareness of (and subsequent dependence on) the runtime state or readiness of a service provider is indicative of tightly coupled behavior.
一个服务拓扑视图显示了实际的服务到服务的关系，包括下钻服务状态和指标，因此您能够跟踪您的服务流。

如果使用状态机服务的客户端为当前状态调用了错误的操作，则该客户端将接收一个错误，使其知道将发生什么情况。
If a client using your state machine service calls the wrong operation for the current state, the client will receive a fault to let it know what happened.
为了跨来自多个客户端的多个请求来维护状态，服务器应用程序必须具有一种方法来确定每次交互中将要更新的状态数据。
