Companies have long sought to integrate existing systems in order to implement information technology (IT) support for business processes that cover all present and prospective systems requirements needed to run the business end-to-end. A variety of designs can be used to this end, ranging from rigid point-to-point electronic data interchange (EDI) interactions to Web auctions. By updating older technologies, such as Internet-enabling EDI-based systems, companies can make their IT systems available to internal or external customers; but the resulting systems have not proven to be flexible enough to meet business demands.
A flexible, standardized architecture is required to better support the connection of various applications and the sharing of data. SOA is one such architecture. It unifies business processes by structuring large applications as an ad-hoc collection of smaller modules called services. These applications can be used by different groups of people both inside and outside the company, and new applications built from a mix of services from the global pool exhibit greater flexibility and uniformity. One should not, for example, have to provide redundantly the same personal information to open an online checking, savings or IRA account, and further, the interfaces one interacts with should have the same look and feel and use the same level and type of input data validation. Building all applications from the same pool of services makes achieving this goal much easier and more deployable to affiliate companies. An example of this might be interacting with a rental car company's reservation system even though you are doing so from an airline's reservation system.
Web Solutions towards SOA:
With the day to day advancements in technologies and standards in the web technologies there is a serious demand in SOA based architecture in this domain of technology. With the growth in demand and competition towards to the service the portals are moving much faster to the newer innovations which consume huge storage space, band width, processing cycles, request cycles. So the scalability & life cycle management has to be decided well in advance before the system in designed. Else the developed system expires or gets outdated before the system is released. So moving the e-business & e-related solutions towards has became a necessity for the e-entrepreneur
It's lower cost, easier integration, faster to change that's service-oriented architecture.
