My question is, given the following design, what are good ways to implement the communication between the Network I/O servers and the logic server. The logic server cannot depend on a specific network I/O process to work, eg if a Network I/O process goes down for some reason the logic process must continue to function. All Network I/O processes and the logic process are child processes of the Lobby Server Process.

Essentially I am asking for ideas on how to implement the communication between sibling processes(Network I/O and Logic Server). This is all written in Node, if there is a specific solution for Node, but a general idea would be helpful too.

This is a follow up on this question.

PS: I am sorry if this is too general of a programming question and doesn't belong here. If this is the case I will remove it.

Answer 1

The simplest and most scalable solution, in my opinion, would be ZeroMQ with this binding for Node . ZeroMQ is a powerful implementation of the "sockets" concept whose communications backend can vary, so that it can be used equally well locally and remotely.
