Web services are software systems that enable interoperable machine-to-machine communication over a network, typically the Internet. They allow different applications or systems to exchange data and invoke specific functions, regardless of the operating system or programming language they are built with. Web services are often used in cloud computing and can be described, published, located, or invoked over the network.
Here are some key characteristics of web services:
-
Standardized: Web services use open protocols and standards such as TCP/IP, HTTP, Java, HTML, and XML. They provide a consistent and reliable way for applications to communicate with each other.
-
XML-based: Web services use XML (Extensible Markup Language) to encode all communications, enabling the exchange of structured data between client and server applications.
-
Self-contained and modular: Web services are independent and can be developed, deployed, and updated separately from other applications. They are designed to be reusable and easily integrated into various systems.
-
Distributed and dynamic: Web services can be local, distributed, or web-based, and they can adapt to changing network conditions and user demands.
-
Interface-based: Web services have an interface described in a machine-processable format, often using WSDL (Web Services Description Language). This allows other systems to interact with the web service in a prescribed manner.
-
Application-to-application (A2A) communication: Web services facilitate direct communication and data exchange between applications, without the need for user intervention.
