The following diagram shows a schematic representation of the system:

Diagram 6.26. The schematic design of the streaming application

The preceding diagram can be described as follows:

1. This is the point of integration with the Gitter API. As we can see from the preceding diagram, the communication between our server and Gitter is a streaming ...
