Intersystem Communication

The purpose of middleware is to connect two or more applications in integrative programming.

Middleware can be classified into categories such as cloud integration, B2B integration, application integration (A2A), and data integration.

Cloud integration middleware is used to integrate and communicate between cloud services, cloud-based applications, private clouds, trade hubs, and other cloud resources.

<p>B2B integration middleware is used to integrate customer, provider, and partner interfaces with various data resources and company-managed applications.</p> Signup and view all the answers
