What is SOA Development?
SOA development or Service Oriented Architecture makes use of a service-based interface. Different services like attaining, delivery, consumption etc are considered as sets of inter-related services. In SOA development, the computing system is divided based the different applications. Each segment is presented as services in these applications. But unlike other cases, the service is kept away from the reach of the implementation sector. This means that an SOA development engineer can create the application in any computer language without bothering about the implementation language.
SOA development services are self dependant with the interfaces mostly built in XML. The services are described using Web Services Description Language. Each SOA service communicates with the other via XML Schema. These messages are processed as specific entities in specialized enterprises and are considered to be valuable business documents. .In SOA development, each service is recorded in a directory registry. Any particular service can be recalled specifically. The service registries work by UDDI standard (Universal Description, Definition and Integration). The SOA services have a predefined Quality of Service. According to it, all services should have authentication and authorization. The right to invoke services should be limited and the service interface should also be reliable.
Business look up to SOA development usually when they are in the verge of expanding and require some kind of technology to merge their existing infrastructure with the newer advances. Businesses are usually run by certain applications. With advancements make in the different sectors of the business, changing the whole application and beginning from scratch is just not possible. Any kind of changes in the business structure should be dealt with promptly to beat the competition in the field. With the change in business requirement, the company should be able to boost up the existing application to support the development. Whole new interactive service architecture should be created to support the business at such a stage. SOA gives all the help that the company requires to create newer services and integrate it with the existent application, avoiding the need for creating the application from scratch. The services thus created can be made available to the customers via different streams. The inherited applications are exposed as simply services alone and the integrity of the IT infrastructure is maintained. Sometimes, more than one service is coupled together to become a composite service. SOA development is a difficult task as it has to be created for the provider and the consumer ends together.
