synthetic multi-node crossbar system implementation

I am implementing a system composed of a collection of small systems, ie. Raspberry, Yun, Beaglebone, the occasional PC. Crossbar.io has real promise ... but, as I understand it, doesn't currently support multiple nodes. Am I correct? Does anyone know when that might happen?

In the meantime it occurred to me that each individual node can offer an http interface that I might be able to use for my purposes. My initial thought is to crate workers that wrap access to the web the interface on subsidiary nodes. This fits the overall architecture of the system I want to create - does it have any merit? Is it tractable? I'm new to websockets - and insight would be a great help.

Thanks for your time, Al

In general that does sound like a fit for Crossbar.io.

There is no timeline on multi-node (i.e. multiple routers), but we hope to have at least hot-standby nodes for high availability ready in Q1. Other than for high availability, I think that a single instance should provide sufficient performance for most applications out there - on a single current (non-high-end) Xeon we're talking tens of thousands of events a second, and concurrent connections are mostly limited by RAM (and 100s of thousands on a single box are definitely not a problem). (If you need more than that then I'd be very interested in your specific use case - we want to learn more about our users.)

I don't completely understand the second part of your question: What precisely is the architecture you're planning here? If you're talking about the integrated Web server, then with recent optimizations (it can now use multiple cores) this should be enough for even moderately big sites, and with SPAs you're not likely to ever run into performance issues.

Hope this helps, and I'll be glad to answer in more detail once you've clarified the second part.
