What are Web Services

  • Web services are based on the concept of service-oriented architecture (SOA). SOA is the latest evolution of distributed computing, which enables software components, including application functions, objects, and processes from different systems, to be exposed as services.
  • Web services are loosely coupled software components delivered over Internet standard technologies.”
  • Web services are self-describing and modular business applications that expose the business logic as services over the Internet through programmable interfaces and using Internet protocols for the purpose of providing ways to find, subscribe, and invoke those services.
  • Web services can be developed as loosely coupled application components using any programming language, any protocol, or any platform. This facilitates delivering business applications as a service accessible to anyone, anytime, at any location, and using any platform.
  • Web services are typically implemented based on open standards and technologies specifically leveraging XML. The XML-based standards and technologies, such as Simple Object Access Protocol (SOAP); Universal Description, Discovery, and Integration (UDDI); Web Services Definition Language (WSDL); and Electronic Business XML (ebXML), are commonly used as building blocks for Web services.
