Web Service: Definition, Benefits, How it Works, and Its Functions

Web service

Web Service – The use of internet technology in modern times is now increasingly massive. Where internet access is easier for us to get, which has a definite impact on internet data loads that are also higher.

Which web service technology is one way to optimize the performance of the website. Then what is a web service, and what are the types, let’s look at the following article.

What are Web Services?

What is a web service?, From the name alone we can have an idea that this web service is an application that allows data exchange using internet-based XML which allows communication between applications.

Later, this technology will contain a series of protocols and include standards that will be useful for exchanging this data.

In addition, technology includes a series of communication methods between machines that use their own language that is not tied to operating systems and other programming languages.

One example of a service site is when an application is with the Java programming language, this machine will be able to interact with other machines that use other programming languages.

By using this technology, it is possible to exchange data between devices in client and server format. Later, all data stored on the server can be retrieved by the client remotely, using any operating system, application, and programming language.

How Web Services Work

Web service as a system that works in an integrated way of working. There are several supporting technologies such as REST, and SOAP. In addition, there are also supporting protocols such as HTTP, FTP, or SMTP.

With this technology, the client can send messages in SOAP or REST format. This message itself contains an XML document which will later be transferred over the network via protocols such as HTTP. Which this message can be conveyed to the server. Which the server itself can respond by fetching and displaying the requested data. Typically, the server will respond by displaying the data in XML, HTML, or JSON format.

The following is how web service technology works:

  • The client gives a request message to the server
  • The message comes from the client in XML format. Later the following message is sent to the server using a certain protocol, such as HTTP. The following messages can be sent first to this facility.
  • Later, technology can check the validity of these wishes. In this stage, this tool can also check whether the object is correct or not. Later, this tool can also change the message format to a format that the server understands
  • The server can produce the following messages and respond to them. If the following request is available in the database, then the request is accepted. If not, then the request is rejected.
  • Furthermore, the server can provide additional data, its function is to carry out validation and change the format of this message into a format that is understood by the client.
  • Finally, the requested data can be received by the client and can be displayed in an easy-to-understand format.

Benefits of Web Services

The web service has several benefits in the world of internet technology, including:

  • Interoperabilitas

Web services provide services with connections between applications to communicate with each other and to share data and services.

Other applications that typically use web services such as VB or .NET which can talk to java web services or vice versa. These systems are typically used in creating independent application and technology platforms.

Interoperability itself has a definition in the form of the capability of a system whose interface is shown as a whole. To interact and use with other products or systems, now or in the future without restrictions on access or implementation.

  • Standard Protocol

Web service is a web site service that has industry and communication standards. Transport services, XML messages, Service Description, and Service Discovery Layers already use protocols that are well defined by the web service protocol stack. Standardization of the protocol stack itself adds benefits such as reducing costs due to competition and increasing the quality of a business.

  • Low Cost Communication

Web services that use the SOAP mechanism whose protocol is HTTP, will have an impact where internet services become much cheaper. Besides SOAP web service FTP.

  • Show Functions on Network

it is possible that managed code units can be used remotely in HTTP invocations. This system can be activated by executing requests via HTTP. Web services also allow users to expose existing code over the network.

Web Services Function

The following are some of the functions of web services that have an important role in the development of internet technology, including:

  • Making Data Accessible from Anywhere and Anytime

The function of the first web service is to make the website accessible from anywhere and anytime. This is a solution to the problem of high website interoperability. With this technology, access can be smoother.

  • Allows Access Through Multiple Protocols

Another function of the web service is that it allows web sites to be opened through many protocols. This also allows web site access to be much easier.

  • Allows Interaction Between Formats, Systems, and Languages

Web service is a technology that also makes sites able to interact with each other even though there are differences in format, operating system, or programming language used between the client and server sides. This technology allows the connection to always be able to occur together with all these differences.

That’s more than one benefit of this technology. Apart from the examples of the benefits of service sites like the one above, this technology also has several other benefits such as for monitoring, routing, management, and others.

Web Services Technology

It has been said before that there are supporting technologies for web services, namely SOAP and REST, along with their explanations.


SOAP or Simple Object Access Protocol is a standard protocol that allows applications to exchange information. In short, SOAP is a protocol that allows the exchange of structured messages in XML format between applications.


The next technology is REST, REST or Representational State Transfer is the architecture of a standardized computer system. This technology can allow between systems that communicate with each other.

SOAP and REST Technology Differences

Description SOAP REST
Communication protocol HTTP, HTTPS, SMTP, FTP HTTP, HTTPS
Bandwidth usage By writing a lot of XML format, the bandwidth is relatively wasteful. Because XML is not used, it saves a lot of bandwidth.
Usage trends Even though many are switching to REST, there are still many who use SOAP which is for application integration to legacy systems in companies. Many are used by leading web service providers such as Yahoo, Twitter, flickr, bloglines, technorati, Google, ebay, and amazon, among others.
Writing rules Strict, following the XML specification (SOAP v1.2) There are no special specifications
Response format XML with the SOAP specification. Difficult to read and understand at the same time. XML, JSON, or other plain text format. Can make it easier for the recipient to read and understand it.
Attachment file Can Can’t
The nature of web services in general Closed, more intended for companies or vendors Open, accessible to anyone
Web caching It’s quite difficult Easy, because it uses URI
Standard use The old standards still use XML, HTTP and SOAP are used together Still using existing Standards, such as XML and HTTP
Development tools Many, commercial and open source Only a few are not really needed.
Management tools Need it, it’s expensive. Using existing tools on the network system
extensibility Yes, many extensions including standard WS-* Relatively non-extensible
Ease of implementation It’s easy if we already have a SOAP based environment Easy
