Middleware solutions are software that acts as a bridge between different applications or services, enabling them to communicate and share data effectively. They simplify the integration process by providing common functionalities, such as messaging, authentication, and data management, which can be reused across various systems. This helps organizations streamline their operations and improve efficiency. These solutions are essential in complex IT environments where multiple systems need to work together. Examples of middleware include message brokers, API gateways, and database middleware. By facilitating communication and data exchange, middleware solutions enhance the overall performance and scalability of applications.
