Web Services
Web Services are a standardized way for applications to communicate over the internet using open protocols like HTTP and XML/JSON. They enable different software systems, often built on diverse platforms or languages, to exchange data and functionality seamlessly. Common implementations include SOAP-based services and RESTful APIs, which facilitate interoperability in distributed computing environments.
Developers should learn Web Services to build scalable, interoperable systems, such as microservices architectures, mobile app backends, or integrations between enterprise applications. They are essential for creating APIs that allow third-party developers to extend functionality, enabling features like payment processing, social media logins, or data aggregation from external sources.
