Simple messaging scenario

A simple QAnywhere messaging setup is illustrated in the following diagram. For simplicity, only a single client is shown. However, a typical scenario has multiple clients with the server message store existing to transmit messages between them.

QAnywhere architecture for simple messaging.

This setup includes the following components:

Messages are sent and received by QAnywhere clients. Messages at the server will not be picked up until the client initiates a message transmission. QAnywhere clients use policies to determine when to carry out a message transmission. Policies include on-demand, automatic, scheduled, and custom. The on-demand policy permits the user to control message transmission. The automatic policy initiates a message transmission whenever a message to or from the client is ready for delivery.

See Determining when message transmission should occur on the client.
