Middleware
Middleware is software that acts as an intermediary layer between different applications, systems, or components, enabling communication, data exchange, and integration. It abstracts underlying complexities, providing services like message routing, transformation, security, and transaction management to facilitate seamless interactions in distributed environments.
Developers should learn middleware when building distributed systems, microservices architectures, or integrating disparate applications, as it simplifies connectivity, enhances scalability, and ensures reliability. It is essential for use cases such as enterprise application integration (EAI), API management, and real-time data processing, where it handles cross-cutting concerns like logging, authentication, and load balancing.
