But I'm fairly confident with its stability, at least in this case which is really the simplest possible use case for mysql-proxy. I don't think I'm the only one out there using mysql-proxy in production. We haven’t been using this setup very long at all, so it’s hard to say.

I figure that the cluster would coast along fine for a while, so it wouldn't cause an immediate outage but reduced performance at worst. So my plan is to eventually monitor all cluster health metrics and the Scalr node health with a pager system so that node could be quickly restored if it failed. I'm still looking for the perfect monitoring software. I’ve considered this scenario.

I'm glad that Scalr is working out well for you. You advise using a non-AWS (non-ephemeral) server for Scalr. What happens if that single server has an undetected failure?
