Conceptual Relationship
• SOA is a radical departure from client-server architecture.Current SOAs still employ some of the technologies originally used to build client-server applications.Though more sophisticated,SOAs introduce complexity that sharply contrasts the simplicity of a two-tier client-server architecture.
• Distributed Internet architecture has much in common with SOA,including a significant amount of its technology.However,SOA has distinct characteristics relating to both technology and its underlying design principles
Multi-Tier System Architecture
• RPC-based
– Client and middleware server is tightly coupled
• Remote Object based
– Remote objects communicates through standard interface languages
– Object models:OMG CORBA,SUN Java RMI,MS DCOM
• Web based
– Browser + “Dynamic content generation”
– Enabling techniques:CGI,Java Servlet/JSP,MS ASP
Distributed Object Computing
• Coupled with a powerful communications infrastructure,distributed objects divide monolithic client/server applications into self-managing components,or objects,that can interoperate across disparate networks and operating systems.
– SUN J2EE
• JavaTM 2 Platform,Enterprise Edition
– MS DCOM
• Distributed Component Object Model
– OMG CORBA

概念的关系
• SOA是一个激进离境从客户端-服务器架构.目前SOA的仍是聘请一些技术原本是用来建立客户端-服务器应用程序.虽然更先进的,SOA的引入复杂,尖锐对比的简单了一个两层的客户-服务器结构.
•分布式互联网架构有很大的共通点与国家海洋局,包括了大量的技术.然而,国家海洋局具有鲜明的特色有关的技术和其基本的设计原则
多层次的体系结构
•基于RPC
-客户端和服务器中间件是紧耦合
•远程基于对象
-远程对象进行通信,通过标准的界面语言
-对象模型：o mgC ORBA的,孙J avaR MI的,她的D COM
•基于Web
-浏览器+ “动态内容的一代”
-有利的技术：C GI模式,J avaS ervlet的/ J SP的,她的A SP
分布式对象计算
•再加上一个强大的通信基础设施,分布式对象鸿沟铁板一块,客户机/服务器应用到自我管理组件,或物体,即可以互通各地分散的网络和操作系统.
-孙的J 2EE
• javatm 2平台,企业版
-女士的D COM
•分布式组件对象模型
-o mg的C ORBA
