Microsoft's SOA in the real world note 08-Chapter 1 General architecture functions and SOA abstract modelsWe can also use these five common architecture functions as a set of perspectives for observing and understanding SOA abstract models. These five architecture functions can serve as a set of lenses to help us observe and better understand the challenges we fa

Not long ago I saw a movie Among all the core principles of SOA, the most basic is the loose coupling between service providers and consumers. the core flexibility and reuse advantages of SOA depend on the ability of service providers and consumers to operate independently within the terms and conditions of the service contract used to describe interactions. For a specific

It developers, especially IT security professionals, have struggled for years to create an enterprise-class identity control mechanism. One of the most well-known initiatives and models in this field is single sign-on (SSO), where the identity of a single end-user can be passed between systems and recognized throughout the enterprise. In today's IT environment, security issues also have to deal with service-oriented environments and cloud computing (cloud). Many corporate security professionals

Overview Bea and SOA In order to gain the competitive advantage, the enterprise must make the technology to serve the business target effectively. BEA is committed to promoting the overall application infrastructure compatibility through open standards and SOA (service-oriented architecture) to help enterprises quickly realize it value. SOA is an IT strategy th

The framework takes the SOA paradigm as the guiding ideology and provides a feasible solution for heterogeneous system integration, interoperability and distributed application. 1. Introduction to SOA Platform 1.1. Overview

In the previous chapter, we briefly discussed the simple understanding of the service layer in the architecture design, where we will continue the architecture of the service layer, in this section we will focus on distributed services. In distributed systems, the presentation layer and the business logic layer are not in the same physical deployment, so we must have distributed services, published in a contractual way in the network, our focus is on services, service-oriented programming, which

Some time ago I read the SOA in practice-the art of distribued system design written by niclai M. josutis. The whole book is a summary of josutis's experience, many of which come from practice. The book provides the most concentrated Summary of SOA using five ppt files, 1. What is SOA? SOA is a paradigm to implement

In IT publications and conferences, the term "governance" has been constantly mentioned for some time, but in terms of technology, these discussions are usually at best nowhere near. This article starts with the basic concept of IT governance, and the governance of the design phase and subsequent runtime is a good guide for developers. Imagine an organization that is implementing an SOA project. Everyone is excited by the adequacy of the project budg

I've been working for a client recently, and they have a lot of Java EE Apps deployed on WebLogic 8.1 that require me to help them transform their application assets into SOA service assets. They have strict deadlines, so they can't make big changes to the application code. In the discussion, they constantly raise questions about Web services, and I feel that people tend to think of web services as a component block of

SOA is an architectural change, and since it is a change, there must be an intrinsic reason for the transformation of this architecture. In the past few decades, the application architecture has undergone 3 great transformations, from terminal/host-to-client/server-->browser/server, without exception, complexity of the program, variability of requirements, reuse of resources, etc. is the internal driving force that drives structural change constantly.

Services with the characteristics described by SOA will have the following business benefits.1. Enhance business mobilityEnhancing business mobility is the most important business benefit of SOA so far. For many organizationsNew business needs and fast response business mobility are more important than development efficiency. Two key elements of business mobilityIs speed and flexibility ).Speed: it refers t

The vice president and R D Director of Burton said that SOA development is already very difficult, but if you use waterfall development methods, it is very difficult to do well and it is difficult to obtain user needs. California, San Francisco-Burton Company Anne Thomas manes, Vice President and R D director, said: SOA Development It is already very difficult, but if you use the waterfall devel

applications are in the master bank. The master bank cannot provide personalized services for each branch, and the branch has no ability or opportunity to provide personalized services. If the problem of differentiation cannot be solved, it is impossible to provide differentiated services for customers. After the data is centralized, the branches need to collect and analyze the data. The data must first pass through the master line, and the master line cannot provide data based on different nee

The Universal Device Interconnect Framework (CDIF) is a Web-based connectivity framework, and some open source implementations are currently housed in the Github-out4b/cdif:common device Interconnect framework. CDIF is a JSON-based SOA software framework. CDIF provides the client app with the same abstraction capabilities as the XML-based WSDL language and the SOAP protocol, but a much simpler JSON-based implementation that is also well-suited for the

other.The process of the development of it programming language is actually a process of gradually reducing the coupling, and also a gradual separation between interface and interface implementation.But the Web Service soap is a standard transport protocol, but it is a special protocol, a special technology that does not support other transport protocols such as RMI, so Web service is bound to specific SOAP technologies.By understanding the history of it and the programming language, you can ge

At first glance, there seems to be nothing special about SOA security. After all, it (as with other architectural scenarios) involves the same basic topics as authentication, authorization, identity, trust, confidentiality, integrity, and policy management. Even so, the SOA architecture is more difficult to control safely-enough to make security analysts tired of dogs. 1. Security can not violate

SOA (service-oriented Architecture), Chinese full name: Service-oriented architecture.SOA enables the separation of systems into different services, using interfaces for data interaction, and ultimately the purpose of integrating systems.Professional words always make people mengmengdongdong, look tall on, but just don't know what in BB ....
