Client and server roles in IBM® EMM

IBM® EMM application components can act as either the client or the server in a communication, depending on the situation.

Most IBM® EMM applications consist of two parts.

The web application. The web application is the component that users access through a browser.

The server (for example, the Campaign listener and the Marketing Platform API server). This component is accessed programmatically.

The following examples and diagrams illustrate the roles played by IBM® components in various communications.

Example 1 - Communication between a browser and an IBM® EMM web application

When users communicate with IBM® EMM web applications through a browser, the browser is the client and the IBM® EMM web application is the server.

Example 2 - Communication between components of one IBM® EMM application

The two components of a single IBM® EMM application can also communicate with each other programmatically. For example, when the Campaign web application sends a request to the Campaign listener, the Campaign web application is the client and the listener is the server.

Example 3 - IBM® EMM components playing both roles

An IBM® EMM application component can communicate as a client in some exchanges and as a server in others. An example of these relationships is shown in the following diagram.
