What is SOA and its benefits ?

What is SOA ?

• An IT architecture strategy for business solution (and infrastructure solution) delivery based on the concept of service-orientation.
• An architectural principle for structuring systems into coarse-grained services
• Set of components which can be invoked, and whose interface descriptions can be published and discovered.
• aims at building systems that are extendible, flexible and fit with legacy systems.
• promotes the re-use of basic components called services.
• emphasizes the loose coupling of services
• Services can be re-composed when business requirements change.

Business Benefits of SOA

• SOA can help businesses respond more quickly and economically to changing market conditions.
• SOA can be considered an architectural evolution. It captures many of the best practices of previous software architectures.
• The goal of separating users from the service implementations is promoted by SOA.
• The goals like increased interoperability, increased federation and increased business & technology domain alignment can be achieved by SOA due to its architectural and design discipline.
• SOA is an architectural approach for constructing complex software-intensive systems from services.
• SOA realizes its business and IT benefits through utilizing an analysis and design methodology when creating services.
