Millions of Apps: What we've Learned
summary
Claims that matter: Heroku-backed observations and practical fixes for real apps, not theory. Concrete recommendations include keep secrets out of source control and use env vars for config with release-managed rollbacks and add‑ons that inject credentials. Emphasis on dev prod parity (DBs, versions, production snapshots for local testing), log aggregation and metrics (Papertrail, statsd, New Relic) for visibility, and admin-flavored error pages to debug live failures. Notes that Heroku offers an EU region and rolling log retention so searchability can be limited.
