What is the main role of middleware in system architecture?

Middleware in system architecture serves as an intermediary layer between different components or applications, ensuring their interaction and integration.

Main roles of middleware:

• Abstracting the complexity of network interactions and communications.
• Facilitating message exchange, data transformation, and routing.
• Managing transactions and synchronization between distributed systems.
• Enhancing system scalability and fault tolerance.

For example, in web applications, middleware can handle authentication, logging, error handling, and other common tasks not directly related to business logic.
