Service Oriented Architecture Case Study

SERVICE ORIENTED ARCHITECTURE (SOA) - By (Kratika Hada)
INTRODUCTION:
Service oriented architecture (SOA) is a concept of modern information technology. It is an architectural design which is based on loosely coupled with integrating software components which provides services. A service is a piece of functionality which has a service provider in order to deliver end results for a service consumer. Along with web services SOA allows seamless integration by abstraction from complexity thus it provides an approach to deal with the challenges of such complex software environment. It create heterogeneous

The INFINET support layer was custom-made version it said to be middleware.
2.) HOMEGROWN Middleware:
In 1984, a message Queuing middleware is invented. There is one more invention said to be Publish and Subscribe Addressing at that time. Homegrown system is a bad idea, so we divert our mind towards DEC's network and communication group for message queuing product for development and marketing.
Above are some types of inventions which are done and has drawback of SOA.
SOA CASE STUDY:
The first commercial example of end user customer is DEC's initial 3 month consultation at Wells Fargo, which was began in October, 1993. In May of 1995, business case for SOA came, that project was completed in 60 days project cycle because if banking web sites which had already been developed for further internal applications. TO poof the competitive advantage aspects of SOA, the Well Fargo stands for impressive case study.

• INTERACTIVE POINT : Service interactive points has several services such as:
i.)Interactive Services: Using portals and other web technologies, capability and functions are deliver content or data to customer and

From above we have only 3 most important applications which are describe below:
1.) INTEROPERABILITY: Interoperability is the services assume to be possible with other services which are related to hardware and software platform. In this the important task is to changing the current economic conditions. An important issue related to interoperability is integrated traditional enterprises to being replaced by business networks in which each and every company contain some products or services. For reduced cost and increased flexibility this system can supply chains which is more rapidly established to involved the companies. Web service interoperability has both syntactic and semantic
