I returned to AWS, and was reminded why I left | Hacker News

A Hacker News post says an app cut cloud spend by moving off expensive managed services to a simpler setup.

The new stack used VMs, Prometheus, Grafana, Loki, Postgres, Mongo replicas, Redis, custom scaling, and spot instances.

Monthly costs reportedly dropped from about $20,000 to just a few hundred dollars.

The story highlights how managed cloud features can massively raise costs for workloads that do not need them.
