Ask HN: Best back ends to stream raspberry pi data to node web clients

I've been playing the raspberry pi lately and I setup firebase to feed data from the pi to multiple web clients. It works great, but I don't have the perspective of all the options to understand the limitations of this setup.

I am familiar with rails and have thought about setting up sockets or SSE with that to see how that compares. There also seems to be a lot of services out there that deal with this stuff ranging from monogodb, pipelinedb, aws, apache libraries, etc.

Any ideas on a scalable system that allows me to feed data from raspberry pis and feed that out to multiple clients?
