So we have 60$/month on a 1000 users/day average on a monthly basis, based on Anthony's statement.

Please keep me and readers an posterity informed:

  • when the Azure pricing calculator will be "revamped" and will accurately evaluate costs (I can't believe the M of GAFAM shouldn't get this fixed within a couple days)
  • when you will be able to give a clear answer to the costs involved, as precise as the shiny tech bits delivered.

And one last question: Is really al this about technology or is it marketing ? If so, I promess I won't ask anything anymore.

Really wish Chris finished off the thread - dealing with similar issues with signalr at the moment.

Cost issues ?

wow, appreciate you replying 2 years after the comment :)

If you have more than 1000 simultaneous users, how do you plug new ones to another unit ? This would double the messages sent ?

mainly around that. We currently have a bunch of signalr pods on a single node, with a redis backplane on that same node, doing around 1 billion messages a month - imagine it's a stock trading app with price updates - but we're at a loss for scaling this out without a backplane, especially signalr onto other nodes. Have you solved an issue similar to ours? I would absolutely love just plugging into an azure service and making that headache an MS problem :P but it seems we're going to have to deal with this one on our own.

I was notified ;) I'm not the author, and no author replied to my questions neither. Seems that your problem is quite different : I was originally stating that omitting the real cost from the discussion was a bit unfair to the audience (ie marketing-like sponsored posts).
You seem to have the $$ so you may get an answer :)

That is the peculiar thing lol, we do, and we really don't want to deal with this problem - but I think it's inevitable :) and I wholeheartedly agree, the marketing-like posts are all fun and jazzy but conveniently step over a lot of the pitfalls of this stuff, especially cost. MS page advises how to scale out with redis, cautions against it (in our case) but never really offers a good alternative.
