Defining a bus
While we talked about the queue backend system, this hasn't been truly expanded to the concept of a bus. The term bus originates from the hardware buses that transmit data between different components of a hardware system. This makes them a central, multisource, and multidestination part of the system.
A software bus is a generalization of this concept that allows us to interconnect several logical components.
In essence, a bus is a component specialized in the transmission of data. This is an ordered communication compared to the usual alternative of connecting directly to the services through a network, without any intermediate component.
As the bus is in charge of data transmission, that means that the sender doesn't need to know much other than the message to transmit and the queue to send it to. The bus itself will transmit to the destination or destinations.
The concept of a bus is closely related to that of the message broker...
