2SOA是银弹吗?
为什么?
参考答案:
不是;SOA对特定的环境(具有不同所有者的异质分布式系统)而言是理想的解决方案,对其它系统而言可能不是一个好的方法,采用SOA是需要付出一定的代价的。

4为什么SOA架构可以帮助解决IT与业务的不一致?
参考答案:
基于服务可在业务层进行建模,从而支持顶层设计。
并且,在服务实现之前就可对顶层架构进行验证。
5什么是服务契约?
参考答案:
必须有一些机制准确并详细地说明服务向其消费者提供的内容,以及要求消费者提供的内容(输入、规定的操作调用顺序等)。
服务提供者和服务消费者之间的双向协议称为服务契约。

参考答案:

7什么是“补偿”机制,SOA中为什么在事务处理方面主要采用补偿机制?
参考答案:
补偿与事务相关。
补偿不同于“两阶段提交”
(2PC)。
补偿采用“伪回滚”,即采用操作倒退回来的方法。
补偿的优点是更新不必同步,缺点是必须显示提供和调用服务。
因为SOA基本数据服务是原子性而且是无状态的,所以必须采用补偿机制。

9ESB是什么?
为什么SOA中要引入ESB?
参考答案:
企业服务总线(EnterpriseServiceBus),是过去消息中间件的发展。
ESB采用了“总线”这样一种模式来管理和简化应用之间的集成拓扑结构,以广为接受的开放标准为基础来支持应用之间在消息、事件和服务的级别上动态的互连互通。
ESB可以说是搭建SOA架构所必须实现的核心功能组件。
引入ESB原因:
(1)服务总线帮助服务消费者穿越网络找到服务的提供者,使得各类服务得以协同工作
(2)应用程序隔离了内部的具体实现,被包装成一个服务加到服务总线上
(3)总线的修改和替换不影响已经存在各类应用程序
