本文探讨了软件开发中组件与服务的区别与联系。组件作为可复用的代码单元，在同一应用或不同应用间促进代码复用，降低开发成本。而服务则通过组件实现，面向异构环境提供复用能力，并通过开放标准的消息传递来定义服务接口。

It is natural to be confused about the terms component and service, and what they mean. A component is a piece of compiled code that can be assembled with other components to build applications. Components can also be easily reused within the same application or across different applications. This helps reduce
the cost of developing and maintaining the application once the components mature within an organization. Components are usually associated with the object-oriented programming (OOP) paradigm.
A service is implemented by one or more components, and is a higher-level aggregation. Component reuse seems to work well in homogeneous environments; service orientation fills the gap by establishing reuse in heterogeneous environments by aggregating one or more components into a service and making them accessible through messages using open standards. These service definitions are deployed with the service, and they govern the communication from the consumers of the service via various contracts and policies, among other things.
