For instance, there might be one program that tracks inventory, which is different than the interface i. In October of , a manifesto was created about service-oriented architecture.

Service-Oriented Architecture – SOA and Enterprise Architecture

This manifesto states there are six core values of SOA:. Imagine that you have to travel from your home in Atlanta to a business conference or trade show in San Francisco. What are the various steps you might take to get there? After landing, you take another shuttle from the gate to the main terminal, where you have to flag down a taxi or call an Uber to drive you to your hotel. All of these various transportation methods worked together to accomplish your end goal of attending the conference — your car, the shuttle bus, airplane, train, and even walking.

For instance, instead of driving to the airport, you could have walked to a train station or bus stop and gotten to the airport this way. Or you could have driven completely across the country, thus eliminating your need for any other type of transportation altogether. Advanced Search. Advanced Search Basic Search.

To Clear. Our Answers. Butkovic , Randall F. But it is the replacement of large, monolithic applications that have tiny interoperability interfaces, grudgingly provided and not guaranteed, by smaller, modular services that have interface descriptions and contracts, that is the most fundamental effect of SOA. This is the basis for the huge increase in IT system interoperability that SOA can bring, not only within enterprises, but also between enterprises.

With SOA, this software is organized as a set of software services. The services are supported by an infrastructure that, together with the services, improves information flow within the enterprise and between the enterprise and external enterprises. Overview of a Service-Oriented Architecture. This frequently involves a human-computer interface, often implemented as a web interface using portals, etc.

Specific sets of business processes, services, and interfaces are created in the context of a supporting infrastructure as service-based solutions. Each solution solves a particular business problem. The business operations themselves may be organized on the service-oriented principle.

Indeed, there are many people who believe that the greatest benefits of SOA are obtained when it is applied to the business architecture. The infrastructure provides the execution environment for the software services. This includes the basic operating system and networking, and also includes specific support for software services, such as message passing and service discovery.

A major benefit of SOA is that it delivers enterprise agility, by enabling rapid development and modification of the software that supports the business processes. The infrastructure can provide for this by including facilities such as business-oriented scripting languages and model-driven implementation tools. These facilities support not only the creation of new software services, but also the modification and replacement of existing ones: the whole service lifecycle.

They are used via human-computer interfaces by development staff. The infrastructure also provides for storage of enterprise information. SOA can enable easier flow of information within and between enterprises. Service-orientation may extend to the design of the infrastructure, and many people advocate this, but it is not essential to service-oriented software architecture.

It takes far greater knowledge and skill to erect a skyscraper than to build a house. The buildings architect must make complex stress calculations based on an understanding of the properties of the materials involved.

10+ things you should know about service oriented architecture (SOA)

Training and experience are essential for success. Knowledge and skill are also needed for success with SOA. The IT architect must specify the right tools and infrastructure, create the basis for the identification of modular services, and ensure that appropriate implementation governance is in place. Good judgment in these matters is crucial.

Also, just as steel-frame construction is not appropriate for every building, SOA is not necessarily the right approach to solving every IT problem. Its tools and infrastructure cost money, but that is only one part of what is needed. Development and operation staff must have special skills to create and use SOA, and the overall organization structure and culture must be right if the full benefits of SOA are to be achieved.
