Web Services is an architecture that enables communication between different software applications over the internet. It is a widely used technology that allows businesses to integrate their systems with third-party systems and exchange data in a standardized way. In this post, we'll discuss the fundamentals of Web Services, its architecture, RESTful API design, and SOAP protocol.
Web Services are a set of protocols that allow software applications to communicate with each other over the internet using standard messaging formats such as XML, JSON or HTML. They enable businesses to share data and functionality between different applications regardless of their platform or programming language.
The Web Services architecture is built on four basic components: Service Provider, Service Requester, Service Registry and Service Broker. The Service Provider creates the web service, publishes its interface in a registry, and waits for requests. The Service Requester finds the service in the registry and sends requests to it through a broker.
REST (Representational State Transfer) is a popular architectural style for building APIs (Application Programming Interfaces) for web services. RESTful APIs allow clients to access resources on server using HTTP methods such as GET, POST, PUT or DELETE. They are lightweight and scalable compared to other web service architectures.
SOAP (Simple Object Access Protocol) is an XML-based messaging protocol used for exchanging structured information between web services over the internet. It defines a standard format for messages sent between client and server including header information, body content and attachments.
Web Services use standardized protocols to enable communication between different software applications over the internet. The client application sends a request message to the service provider application using a defined interface. The provider receives the message and sends back a response message containing requested data or output.
Web Services offer benefits such as the ability to integrate different systems, share data and functionality between applications, and reduce development time and costs. They are scalable, reliable, and interoperable across platforms and programming languages.
Some examples of Web Services include Google Maps API, Amazon Web Services (AWS), Facebook Graph API, Twitter API, and PayPal Web Services.
