In computing, the term Service-Oriented Architecture (SOA) expresses a software architectural concept that defines the use of services to support the requirements of software users. In a SOA environment, nodes on a network¹ make resources available to other participants in the network as independent services that the participants access in a standardized way. Most definitions of SOA identify the use of Web services (using SOAP and WSDL) in its implementation. However, one can implement SOA using any service-based technology. Originally, the word computing was synonymous with counting and calculating, and a science that deals with the original sense of computing mathematical calculations. ...

Unlike traditional object-oriented architectures, SOAs comprise loosely joined, highly interoperable application services. Because these services interoperate over different development technologies (such as Java and .NET), the software components become very reusable. Object-oriented programming (OOP) is a computer programming paradigm in which a software system is modeled as a set of objects that interact with each other. ...

SOA definitions
| Term | Definition / Comment | | service | (Ideally) a self-contained, stateless business function which accepts one or more requests and returns one or more responses through a well-defined, standard interface. Services can also perform discrete units of work such as editing and processing a transaction. Services should not depend on the state of other functions or processes. The technology used to provide the service, such as a programming language, does not form part of this definition. | | orchestration | Sequencing services and providing additional logic to process data. Does not include data presentation. Also known as choreography. | | stateless | Not depending on any pre-existing condition. In a SOA, services should not depend on the condition of any other service. They receive all information needed to provide a response from the request. Given the statelessness of services, service consumers can sequence (orchestrate) them into numerous flows (sometimes referred to as pipelines) to perform application logic. | | provider | The function which performs a service in response to a request from a consumer. | | consumer | The function which consumes the result of a service supplied by a provider. |
SOA design and development The modeling and design methodology for SOA applications has become known as service-oriented analysis and design. The SOA functions as much as a software development framework as it does as a delivery framework. In order for a SOA environment to operate successfully, software developers need to orient themselves to its mindset of creating common services which clients or middleware then orchestrate to implement processes. Development of systems using the SOA requires a commitment to this model in terms of planning, tools, and infrastructure. Service-oriented analysis and design (SOAD) is an approach to software modeling and development specially designed for the service-oriented architecture paradigm. ...
When most people speak of a service-oriented architecture, they speak of a set of services residing on the Internet or an intranet using "Web services." A set of standards exists which generally feature in all discussions of Web services. These standards include the following: An intranet is a local area network (LAN) used internally in an organisation to facilitate communication and access to information that is sometimes access-restricted. ...
Note, however, that a SOA does not necessarily need to use any or all of these standards to become "service-oriented." The Extensible Markup Language (XML) is a W3C-recommended general-purpose markup language for creating special-purpose markup languages. ...
HTTP (for HyperText Transfer Protocol) is the primary method used to convey information on the World Wide Web. ...
SOAP is a standard for exchanging XML-based messages over a computer network, normally using HTTP. SOAP forms the foundation layer of the web services stack, providing a basic messaging framework that more abstract layers can build on. ...

Why SOA? In simple terms, enterprise architects believe that SOAs help businesses respond more quickly and cost-effectively to the changing market conditions they may face.

Footnotes ¹ An alternative view, particularly after initial deployments, is that SOAs properly ought not dictate physical implementation, so the formal definition should not include "network." High performance SOAs may not be viable deployed to distributed nodes on a network, and separate nodes for every (or most) services could be prohibitively expensive. See, for example, IBM System z9 for an alternative to distributed nodes. Since December, 2001, IBM designates all its mainframes with the name eServer zSeries, with the e depicted in IBMs well-known red trademarked symbol. ...
