A while ago someone posted another SignalR article on www.codeproject.com, and I stated hey you should take a look at this stuff : crossbar.io, and not liking to me someone that is not willing to die by the sword (afting living by it of course) I decided to put my money where my mouth was/is, and write a small article on crossbar.io.
So what its crossbar.io? Well quite simply it is a message broker that has many language bindings, that should all be able to communicate together seamlessly.
Here is what the people being crossbar.io have to say about their own product
Crossbar.io is an open source networking platform for distributed and microservice applications. It implements the open Web Application Messaging Protocol (WAMP), is feature rich, scalable, robust and secure. Let Crossbar.io take care of the hard parts of messaging so you can focus on your app’s features.
I decided to take a look at this a bit more which I have written up here : https://www.codeproject.com/Articles/1183744/Crossbar-io-a-quick-look-at-it
