WebSphere
WebSphere is a family of software products developed by IBM for enterprise-level application integration and middleware. It provides a comprehensive platform for building, deploying, and managing Java-based applications, web services, and business processes. Key components include application servers, messaging systems, and integration tools that support scalable and secure enterprise operations.
Developers should learn WebSphere when working in large-scale enterprise environments that require robust, scalable, and secure Java EE (now Jakarta EE) application deployment. It is particularly useful for industries like finance, healthcare, and government where high availability, transaction management, and integration with legacy systems are critical. Use cases include deploying mission-critical web applications, integrating disparate systems via middleware, and managing complex business workflows.
