The question about SoA promotion strategies is the most frequently asked question recently. There is a management expert who uses Tao, method, and technique to compare several aspects of SOA, which is very interesting. The hierarchy of "Tao" can be considered as management goals such as business agility and it flexibility. "law" refers to the management and control rules of

This article will continue the first part and introduce the impact of SOA on enterprise-level architecture design, and how to ensure that the system architecture can meet different service level requirements in the system when building an enterprise system based on SOA. 1.

The emergence of WebService has brought about a revolution, which makes every system, platform, program directly in the gap, for the integrated enterprise application is a great liberation.

The SOA concept has been well known to most users and enterprises. At the same time, many enterprises have begun to practice SOA and continuously improve the SOA technology and implementation methods in the project implementation process.

As SOA becomes the IT trend, more and more SOA projects are launched. Some projects have failed completely, and some projects have succeeded. How to learn the lessons of these failed projects and develop the vision and strategy you need to plan your SOA roadmap will be key to the success of future SOA projects. Here we

This integration method not only exposes the business logic of the application,In addition, the intersection of business logic leads to tight coupling between various integrated systems, reduces the flexibility of application systems, and increases the difficulty of system maintenance. The above three methods are tightly cou

I. Introduction Today, enterprises are trying to improve their production efficiency, and they are also exploring the restructuring of IT assets. With the help of Service-Oriented Architecture (SOA) technology, IT organizations have achieved certain results in overcoming these problems; however, in most cases, it is only a small part of the entire IT service portfolio. Currently, most of the effort in this area is simply to achieve a "just satisfied"

and CORBA. The difference between the service-oriented architecture of web services today and the past is that they are standards-based and loosely coupled. Widely accepted standards (such as XML and SOAP) provide interoperability between solutions of different vendors. Loose coupling isolates participants in distributed computing, and changes made by one party on both sides of the interaction will not affect the other. The combination of the two means that the company can implement some web se

SOA is a service-oriented architecture, and no one agrees. However, each vendor has its own definition and explanation of what SOA is. Some people say it is an architecture, some say it is a methodology, but few people can give a convincing and easy-to-understand explanation. SOA will be appliedProgramDifferent functional units (called services) are linked by wel

I used to be very clear about SOA ideas, but I guess the article is too wordy, n many people do not see it. Today and Hu Tehui on the Internet, he reprinted a lot of articles on SOA on his blog, he also asked me some questions, I said these questions I have written ah, you have reproduced my article, you should be able to understand. So I want to be a little more straightforward. First, ask: why
