Multi-cloud essentials: How Form3 operates
summary
Form3 runs a CockroachDB cluster stretched across AWS, GCP and Azure with active‑active replication and a customized operator; backups use locality-restricted backups from AWS and GCP simultaneously with a 5-minute RPO (incrementals every 5 minutes, roughly double storage cost). Secrets use HashiCorp Vault, cert-manager and External Secrets Operator to manage customer keys. Observability combines Prometheus + Grafana and custom SQL-driven metrics (contention rate, table size). Schema changes—normalization, column families, TTL jobs and more memory—reduce MVCC write amplification and hit SLAs (p99 ≈100–200 ms).
