They define best practices for modeling a particular industry domain and provide and an extensible framework so that you don't have to constantly redesign your SOA as you add more and more services.
文本其余部分所讨论的很多设计原则都与确保服务的可伸缩性和可维护性密切相关。
Many of the design principles we discuss in the remainder of this article are particularly relevant to ensuring the scalability and maintainability of services.
请注意，除了服务之外，SOA可能还有其他可重用资产，如业务流程模型、参考体系结构和设计模式。
Note that besides services, an SOA may have other reusable assets like business process models, reference architectures, and design patterns.
构建可复用的服务需要创造性的头脑风暴，解决冲突，设计整合，直到到达一个逻辑点，可以进行你的迭代开发。
Building reusable services require creative brainstorming, conflict resolution, design synthesis, and arriving at a logical point that will be used to deliver your iteration.
总之，仔细地进行服务设计可以避免对状态对话的需求，从而简化可靠的可伸缩soa基础结构的实现。
In summary, careful service design can avoid the need for stateful conversations and hence simply the implementation of a scalable, reliable SOA infrastructure.

服务和面向服务的体系结构都是关于使用异构网络可寻址的软件组件来设计和构建系统的。
Services and SOA are all about designing and building systems using heterogeneous network addressable software components.
但是如果错误确实发生了(因为故障在所难免)，则应该验证它们的可访问性和完整性，并设计出增量计划(incremental plan)来修复它们，使您的服务器重新正常运行。
But when they do occur-because failure is inevitable-validate their accessibility and integrity, and come up with an incremental plan for fixing them and getting your server fully running once more.
要帮助您创建一个新的服务规范，模型包含（如前面所提到的）可复用的设计元素集。
