Network exposure: Web services are units of managed code that can be invoked remotely via HTTP, i.e. they can be activated via HTTP requests. You can expose your existing code’s functionality using Web Services. You can share the functionality of your program with other applications once it has been exposed on the network.
Data and services can be shared among different applications using Web Services. It is also possible to use the services of the web services from other applications. It is possible to talk to Java web services from a VB or .NET application, and vice versa. Therefore, Web services are used to make applications independent of platforms and technologies.
A standardised protocol is used for communication between Web Services. The Web Services protocol stack consists of four layers (Service Transport, XML Messaging, Service Description, and Service Discovery). Standardisation of protocol stacks gives businesses many benefits, such as a wide range of choices, a reduction in costs, and an increase in quality.
You can use your existing low-cost internet connection to implement Web Services since SOAP over HTTP is the protocol used for communication. In comparison to proprietary solutions like EDI/B2B, this solution is considerably less expensive.
Other communication means are supported: In addition to SOAP over HTTP, other reliable transport mechanisms can be used to implement Web Services. Therefore, it gives you flexibility to choose the communication means that suit your requirements. You can also implement Web Services over FTP (Web services over FTP) using the FTP protocol.Software modules encapsulating discrete functionality are loosely coupled applications. SOAP and XML are standard Internet communication protocols that enable Web Services to be accessed over the Internet. Any application or Web service can access these Web Services, regardless of their development environment (for example, C++, Java, .NET, PHP, Perl, etc.). Because they are loosely coupled, they can be used by applications developed in a variety of programming languages. People have developed Web Services using Java technologies and used them in VB or .NET applications, for example.
In today’s complex business environment, organisations are using a variety of technologies to distribute computing, for example, EAI, EDI, B2B, portals, etc. All of these technologies can be supported by Web Services, allowing businesses to use existing investments.
The Web Services are self-describing applications, which reduces the time it takes to develop software. The other business partners are able to develop applications and start doing business quickly as a result. As a result, businesses are able to save time and money by reducing their development time.
Businesses can easily find Service Providers using the Web Services automatic discovery mechanism. As a result, your customers will have an easier time finding your services. Exposing your own Web Services to others can also help your business increase revenue.
As a result of Web Services’ ease of connecting with partners, new business opportunities have opened up.
