SOA Architecture Basics ConceptsService-Oriented Architecture (SOA)Before delving into what a service-oriented architecture (SOA) is, create some basic concepts and terms that are not strictly defined, so perhaps some definitions remain controversial in the industry and are ignored for the moment.Architecture BasicsTechnical Architecture (technology Architecture)

Service-Oriented Architecture SOA preambleIn the world of. NET, when it comes to SOA, you should think of web service,wcf, and someone might also mark the Web API in. NET MVC and talk about it in general!Indeed, Microsoft's technology is really driving the world of service-oriented development, except that Microsoft has many services-oriented open source technologies that are even better than Microsoft in s

sources to implement the basic report function. In this way, if the enterprise's requirements change, isn't it necessary to re-develop a report? SOAFor such a typical enterprise application, I think that using SOA can solve the current needs well and lay a good foundation for expansion in the future.First, we need to build an ESB. The construction of ESB may have different functional and performance requirements based on the industry type, scale, an

To better promote SOA development, leading technology vendors, such as Bea, who are collaborating on the creation of Service component Architecture (SCA) and Service data Object (SDO) specifications, have recently released several important results, including important developments in SOA-related norms and technologies. The consortium also created a vendor-independent web site (www.OSOA.org) to provide rele

Component-oriented, new generation of software development models and methods. So what are its norms and standards? Now the answer is getting clearer:SCA. To answer this question, perhaps most people will now say SOA, in fact ' SOA ' is the wrong answer! (Does it seem that the current software world lags behind SOA?!) But on this issue '

architecture (SOA), such as loose coupling (organizational and technical), autonomy, and reliance on existing applications to implement business functions make exception handling more complex. Since each service is designed, implemented and maintained by itself, and can be used in multiple enterprise solutions (which may be unknown at the time of service design), the exception handling implementations for specific services revolve around 3 points: H

2015-01-01 Created by Abalone newI. Background of the programme With the continuous improvement of enterprise informatization, the enterprise IT system is becoming larger, the cross-system process and the system, as well as the internal interface requirements and interface service calls are also increasing.At present, due to the excessive number of interfaces among the mutual systems and the lack of a unified management specification, the interface protocol is too wide, and the interface b

SOA Reference Architecture for product lifecycle management Introduction: Part 1th discusses how Product Lifecycle management (Products Lifecycle Management, PLM) environments vary, and the need to integrate a large number of processes and information sources as part of a complex PLM ecosystem. This paper studies how to apply SOA technology to achieve many of these goals. The organizational structure of t

The 1,soa----an architectural guideline centred on describing and exposing it assets to (remote) services. These services can then be loosely coupled as part of the high-level business process, providing business agility in the face of it heterogeneity. A design approach that aims to improve it adaptability and effectiveness by reusing application-neutral services. SOA is an enterprise-integrated solution

clustered and reusable to support the specific goals and benefits of SOA and service-oriented computing.Solution logic that conforms to the concept of service-oriented design can be considered service-oriented, and these service-oriented logic units can be referred to as "services". Like the paradigm of distributed computing, service-oriented versus object-oriented. Service orientation is deeply related to object-oriented, and is influenced by other

SOA is a technical architecture, EvansDDDIs the philosophical methodology, the direction is different, or the two are very irrelevant. Even in two different directions. UseDDDThe system can be built from scratch to large, and to a certain extent, you needSOA, integrating heterogeneous. If you sayDDDAndSOAIf there is any connection, then the component Componen may be the bond between them. The following analysis of these concepts below, please discuss

I have previously written a post about Amazon Web Services (AWS), which should be the firstWeb 2.0/SOA Infrastructure LeasingLarge-scale market attempts. In an interview with ithome not long ago, it was caused by Microsoft's Internet service bus, a small-scale attempt provided to developers. I have basically enjoyed AWS and its potential markets. Since AWS launched S3, SQS, and EC2, many interesting value-added applications have emerged, for example,

The key technologies used in SOA: XML, SOAP, UDDI, and ESB: to implement SOA, you must first understand the relevant technologies required to implement SOA. The main technologies involved include: XML, SOAP, WSDL, UDDI, and ESB. 1. xmlThe XML 1.0 (eXtensible Markup Language, eXtensible Markup Language) standard is a text-based World Wide Web Organization (W3C) s

Although no one has so far called Eclipse Modeling Project The new super model, it has already met the service-oriented architecture (SOA) that is currently most concerned. This, indeed attracts a lot of attention ... Eclipsemodeling Project (EMP) will be updated to the Europa tool that Eclipsefoundation released on June 29. In addition to providing mature drawing modeling and support for Unified Modeling Language (UML) version 2.0, EMP supports oth

Actual environment topology diagram: In general, FreeSWITCH uses the SOA pattern by default, and in some cases the non-SOA model. Non-SOA model, what can cause problems. will result in a SDP address error, resulting in a voice single pass. Through the topology map can be seen, FreeSWITCH is a dual network card server, the actual environment, the intranet IP phon

, simplicity, HTTP protocol + text serialization is better suited for extranet applications. Of course, this is not absolute. In addition, the TCP protocol here is not limited to the remote invocation protocol must be located at the fourth layer of the OSI network model of the original TCP, which can contain any non-HTTP protocol above TCP. So, to answer the above question, webservices (classic wsdl+soap+http) is the technology that best conforms to the aforementioned

First, let's take a look at the basic concepts, technical concepts, and terminologies of (Enterprise Application System) integration. Apart from the basic concepts, we will talk about the types of integration models similar to SOA, for example, point-to-point, central radiation, and pipelines, understanding the differences between EAI and EIi will also mention the future integration technology-xtp. I. Basic Concepts First, let's clarify some basic con

● Presentation layer (Presentation): in Area 5 in Figure 1, a presentation platform is established through portal and other technologies to facilitate service requests on this interface. ● Business Process Modeling: In Area 4 in figure 1, the SOA meta-model inherits the platform-independent model from the MDA to model the business process. This part is independent of the service design and deployment layer. The main defect of model-driven architectur

Recently, due to the expansion of the system, it was found that the previous software was becoming increasingly difficult to maintain. Every time, the business manager told me the business process clearly, I am explaining the relevant business processes to the programmers before development and maintenance can be conducted. The previous project manager did not leave any documents I am going to clarify the business, write documents, and other things. I saw
