  （面向服务的架构）

面向服务的架构（SOA）是一个组件模型，它将应用程序的不同功能单元（称为服务）通过这些服务之间定义良好的接口和契约联系起来。接口是采用中立的方式进行定义的，它应该独立于实现服务的硬件平台、操作系统和编程语言。这使得构建在各种各样的系统中的服务可以以一种统一和通用的方式进行交互。

A service-oriented architecture (SOA) is a style of software design where services are provided to the other components by application components, through a communication protocol over a network. The basic principles of service-oriented architecture are independent of vendors, products and technologies.^[1] A service is a discrete unit of functionality that can be accessed remotely and acted upon and updated independently, such as retrieving a credit card statement online.

A service has four properties according to one of many definitions of SOA:^[2]

1. It logically represents a business activity with a specified outcome.

2. It is self-contained.

3. It is a black box for its consumers.

4. It may consist of other underlying services.^[3]

Different services can be used in conjunction to provide the functionality of a large software application.^[4] So far, the definition could be a definition of modular programming in the 1970s. Service-oriented architecture is less about how to modularize an application, and more about how to compose an application by integration of distributed, separately-maintained and deployed software components. It is enabled by technologies and standards that make it easier for components to communicate and cooperate over a network, especially an IP network.

SOA架构设计经验分享—架构、职责、数据一致性

• 1.背景介绍

• 2.SOA的架构层次

  • 2.1.应用服务（原子服务）

  • 2.2.组合服务

  • 2.3.业务服务（编排服务）

• 3.SOA化的重构

  • 3.1.保留服务空间，为了将来服务的组合

• 4.运用DDD+GRASP进行分析和设计（防止主观的判断导致错误的假设）

• 5.SOA分布式下的数据一致性

  • 5.1.分布式事务（基于DTC的分布式事务）

  • 5.2.事务补偿（提供正向或反向的操作来让数据在业务上是一致的）

  • 5.3.异步EDA（基于异步事件流来实现柔性的分布式事务）

• 6.总结
