Web Services

Most enterprises have made extensive investments in system resources over the course of many years. Such enterprises have an enormous amount of data stored in legacy enterprise information systems (EIS), so it's not practical to discard existing systems. It's more cost-effective to evolve and enhance EIS. But how can this be done? Service Oriented Architecture (SOA) provides a cost-effective solution. The concept of using SOA towards implementing IT solutions has been increasingly adopted by large and medium enterprises.

Enterprises have invested heavily in large-scale packaged application software such as enterprise resource planning (ERP), supply chain management (SCM), customer relationship management (CRM), and other systems to run their businesses. IT managers are being asked to deliver the next generation of software applications that will provide new functionality, while leveraging existing IT investments. The solution to this is integration technology; the available integration technology solutions, however, are proprietary and do not interoperate with each other.

The advent of web services and SOA offers potential for lower integration costs and greater flexibility. An important aspect of SOA is the separation of the service interface from its implementation. Such services are consumed by clients that are not concerned with how these services will execute their requests. Web services are the next step in the Web's evolution, since they promise the infrastructure and tools for automation of business-to-business relationships over the Internet.

How it work:

Service-oriented architecture (SOA) is an architectural style where existing or new functionalities are grouped into atomic services. These services communicate with each other by passing data from one service to another, or by coordinating an activity between one or more services.

A major focus of Web services is to make functional building blocks accessible over standard Internet protocols that are independent from platforms and programming languages. These services can be new applications or just wrapped around existing legacy systems to make them network-enabled. A service can rely on another service to achieve its goals.

The following figure illustrates a basic service-oriented architecture.
