I think there are others?

I use google pubsub as a stream - it's just me developing our tools. I find it very easy to use and just works.

But maybe that doesn't count as a 'stream' under that definition?

I use GAE to accept and pass to pubsub super fast 1000s/second bursty webhook data, pass to pubsub, which is triggers cloud function to write to DBs. Cloud function retries if there is a write error or timeout or something.

It worked so well I've now just used this as a kind of micro-service for all DB writes I have to do. Now also parsing out other 'processing' services that don't need to respond with data to the request, like for instance an example 'service' we verify and format cell phones with twilio and then update that user profile.
