Web Services are the process or computer architecture in which various computers communicate to one another and form a group via network. This network includes set of rules or programming environment that helps various developers group to either implement different applications or tools provided by third parties or open market vendors or develop their own set of application or software modules. Application Programming Interfaces (API) or Web Application Programming Interfaces (WAPIs) are the modes of popular web services in which it can be made to access through internet and requested service can be taken care of via a remote system. These requests can be triggered by utilizing HTTP requests, to understand further these request varies from platform to platform or according to the set protocol like for example DCOM clients access remote COM types using tightly coupled RPC calls, CORBA need Internet Inter-ORB Protocol (IIOP), Enterprise JavaBeans (EJBs) needs Remote Method Invocation (RMI) Protocol and more or less a specific language (Java) etc. The other two aspects of web service architecture are Simple Object Access Protocol (SOAP) and XML.
How Web Services are implemented?
Web Service is generated by the service provider
Universal Description, Discovery, and Integration (UDDI) registry is described by using Web Service Description Language (WSDL).
UDDI registry receives the service via service provider.
An extra service or user finds and requests the registered service by querying UDDI sometimes including e-business XML (ebXML) registries.
The user develops an application to connect the registered service using SOAP in the situation of UDDI and/or ebXML.
Using XML over HTTP the entire data and messages are transferred from one end to another.
There are various approaches which can be incorporated while developing and implementing the right set of Web Services. Every approach has its pros and cons so depending on your project our experts in TechPasture decide, which would be the best approach forward. The aim remains to provide you best way ahead technologically that not only suits your business requirement but also the budget bracket that you have set for the same. The various approaches of development pattern for Web Services are Bottom-up approach, Top-down approach and Round-trip approach. In the competitive era keeping with times one has to opt for Web Services as an integrated business solution. Web service architectures present a very diverse way of assessment about web and mobile application development. Web Service applications symbolizes the conclusion of each of these architectures in combination with the Internet for maximum acceptance and popularity.
