Web Service can be defined as a process, method, way, and or a system of communication of two different electronic devices in between the World Wide Web, which primarily consist of various software performing its functions on a given network address over the web and or through the cloud. And in terms of its job functionalities specifics, Web Service is always switched on as it serves as computing resources for computations of computer related programming software and applications, storage device and services, and as a meter recorder/tracker service device.
One of its major roles is to support machine-to-machine network interaction. It comprises of a special kind of interface that are specifically formatted and designed in order for other machines to read with utmost comprehension. According to World Wide Web Consortium (W3C), other systems are able to interact with web services depending on the way of it is designed and described as Simple Object Access Protocol (SOAP) messages, and usually it is expressed using HTTP and XML serialization in connection to other Web-related matters.
Also, according to World Wide Web Consortium (W3C), Web Service is classified into two major classes: REST – Compliant Web Services. The primary role/function of the service is to control and manoeuvre XML representation of various Web Resources which is of different operations that comprises of different set of uniform stateless set. Arbitrary Web Services, the exposure of arbitrary group of operations.
So in layman’s term, web services are like interpreters. They interpret all various web programming codes which allow all kinds of web applications to run and function smoothly towards all sorts of purposes such as web information and or news feeds and issue, multimedia and other web services through all devices and applications, and other web programs and facilities. This allows all sorts of applications coming from kinds of sources from kinds of communication which saves users from the time in custom-coding considering that most of the XML, they are not compatible in any other application and operating systems or programming languages.
With the integration of web-based applications which comprises of WSDL, SOAP, XML, and UDDI open standards through an Internet Protocol. Thus, the procedure starts with the tagging of data by XML, transferring data by SOAP, the describing of the services available is being done by WSDL, and in terms of the availability of the services are being run by UDDI. Basically, in the world of Information Technology, this is how web services works.
Web Services does not consist of Graphical User Interface (GUI), a system which takes care of the graphic capabilities of a computer enabling easy usage of computer programs. So comparing it to the traditional models of web servers and or web page system, Web Services comes with data processing that has the ability of sharing of business logic which runs through different networks.
Famous Web Services
Some of the famous web services that is running and operating in the Internet are Google, Twitter, YouTube, Flickr, Amazon, Facebook, Yahoo!, Foursquare, Wikipedia, Bing, LinkedIn, Instagram, PayPal, and a lot more famous domains/website. And if we’re to see these domains thoroughly, one thing they have in common is that they all use and runs 24 hours a day, 7 days a week. The services being rendered by these domains, apart from their popularity are continuous and as such, the programming systems and web services of these domains are tracked and monitored continuously as well. This is to make sure the smooth flow of operations of these websites to meet and cope up with the demands in terms of the types of service being offered by the said websites.
So imagine how vital and important the roles of these web services are, particularly with the integration and incorporation of web services with the services being offered of these websites? Definitely, if it wasn’t for these web services, these websites wouldn’t be able to do and run properly as expected from them.
