Web Services in Cloud Computing

What are web Services in Cloud Computing

Cloud Computing Web Services involve integrating web-based applications that are implemented to allow open standards over an Internet Protocol backbone. It enables two electronic devices to communicate over a network. The means are provided through different standards that include HTTP, XML, SOAP, and WSDL, through which various applications can communicate with each other. This makes the data and service provision across different systems and platforms inter-operable and cooperative in the cloud....

Components of Web Services

XML (Extensible Markup Language): XML can be described as a document tagging language designed to use tag-based encoding when facilitating the creation of structured documents. This is used in forming the format of structuring information being exchanged between web services. SOAP (Simple Object Access Protocol): This is a communication platform that has no relation to the transportation protocol. This is a specification for a framework, but SOAP is a messaging protocol based on XML, and it is intended to be used together with other protocols and technologies for building such a framework. The most beautiful thing about web services and SOAP is that everything goes through HTTP, the standard web protocol. WSDL (Web Services Description Language): A Web service cannot be used if it can’t be found. The implementing client has to know where the web service is located. Also, to invoke the correct web service, the client application has to understand what the web service does. This is done with the help of Web services description language(WSDL). The WSDL file is another XML-based file describing what the web service does to the client application. With this WSDL document, the client application will know where the web service is located and how to use it. UDDI (Universal Description, Discovery, and Integration): UDDI is a discovery of Web services and publishing of Web services in the discovery type of repository. One of the possible functionality deliverables includes the ability to let a service provider advertise their services and enable the consumers to search for services that they need. REST (Representational State Transfer): REST is a working model or, more accurately, a set of standards for building web applications. While the SOAP type of web service messages use the XML language and are based on complex protocols, the REST type of SaaS messages utilizes the HTTP standards and interchange data with the help of JSON. HTTP (Hypertext Transfer Protocol): HTTP is a protocol that is used when working with the WWW, to exchange information between the clients’ and the servers’ sites. The protocol is often used for Web services right now – both for services based on SOAP and REST. JSON (JavaScript Object Notation): JSON is an easy-to-read data format for the exchange of data that is particularly used in REST-based web service systems. A specific type of markup language, it is more compact than XML and is consistently chosen for its suitability and convenience....

Conclusion

In conclusion, web services are an important technology that fosters compatibility and interaction between applications across disparate platforms. They rely on industry-standard platforms and protocols such as XML, SOAP, and RESTful to ensure good interoperation. Important characteristics that clear its benefits such as reusability, loose coupling, and security raise flexibility and robustness in the new distributed systems. In conclusion, web services form a flexible and effective means of glueing together large and integrated, as well as interoperant, software environments....
