Web PubSub[0] is a low level, scalable web sockets backend.
SignalR[1] is a higher level tool on top of web sockets that has support for some higher level abstractions like groups.
Fluid Relay[2] is probably the one closest to this tech that any team could take "off the shelf" to achieve similar features using their open source Fluid Framework[3] client. My understanding is Fluid Relay powers some of Microsoft's own collaborative products. Not sure if other direct users of this service.
