I'd love to see a comparison with Mimir. Some of the problems that this article describes with Prometheus are also solved by Mimir. I'm running it in single binary mode, and everything is stored in S3. I'm deploying Prometheus in agent mode so it just scrapes and remote writes to Mimir, but doesn't store anything. The helm chart is a bit hairy because I have to use a fork for single binary mode, but it has actually been extremely stable and cheap to run. The same AZ cost saving rules apply, but my traffic is low enough right now for it not to matter. But I suppose I could also run ingesters per AZ to eliminate cross-AZ traffic.
