The key is independent services with defined interfaces that can be called to perform their tasks in a standard way, without a service having foreknowledge of the calling application, and without the application having or needing knowledge of how the service actually performs its tasks.

SOA enables the development of applications that are built by combining loosely coupled and interoperable services. These services inter-operate based on a formal definition or contract, e.

About the Author

The interface definition hides the implementation of the language-specific service. SOA-based systems can therefore function independently of development technologies and platforms such as Java,. NET, etc.

Services written in C running on. NET platforms and services written in Java running on Java EE platforms, for example, can both be consumed by a common composite application or client.

Applications running on either platform can also consume services running on the other as web services that facilitate reuse. Service-oriented modeling is an SOA framework that identifies the various disciplines that guide SOA practitioners to conceptualize, analyze, design, and architect their service-oriented assets.

The Service-oriented modeling framework SOMF offers a modeling language and a work structure or "map" depicting the various components that contribute to a successful service-oriented modeling approach. It illustrates the major elements that identify the "what to do" aspects of a service development scheme. The model enables practitioners to craft a project plan and to identify the milestones of a service-oriented initiative. SOMF also provides a common modeling notation to address alignment between business and IT organizations.

It can also simplify interconnection to—and usage of—existing IT legacy assets. With SOA, the idea is that an organization can look at a problem holistically. A business has more overall control. Theoretically there would not be a mass of developers using whatever tool sets might please them. But rather they would be coding to a standard that is set within the business. They can also develop enterprise-wide SOA that encapsulates a business-oriented infrastructure. SOA has also been illustrated as a highway system providing efficiency for car drivers.

The point being that if everyone had a car, but there was no highway anywhere, things would be limited and disorganized, in any attempt to get anywhere quickly or efficiently. It captures many of the best practices of previous software architectures. In communications systems, for example, little development of solutions that use truly static bindings to talk to other equipment in the network has taken place.

By embracing a SOA approach, such systems can position themselves to stress the importance of well-defined, highly inter-operable interfaces. A service comprises a stand-alone unit of functionality available only via a formally defined interface.

Services can be some kind of "nano-enterprises" that are easy to produce and improve. Also services can be "mega-corporations" constructed as the coordinated work of subordinate services.

Reasons for treating the implementation of services as separate projects from larger projects include: Separation promotes the concept to the business that services can be delivered quickly and independently from the larger and slower-moving projects common in the organization. The business starts understanding systems and simplified user interfaces calling on services.These services inter-operate based on a formal definition or contract, e.

Services If a service-oriented architecture is to be effective, we need a clear understanding of the term service. The request and subsequent response connections are defined in some way that is understandable to both the service consumer and service provider.

Some of the people who helped bring this book to market include the following: Service-oriented architectures are not a new thing. SOA promises to simplify testing indirectly. Services are autonomous, stateless, with fully documented interfaces, and separate from the cross-cutting concerns of the implementation.
