Status: OUT
Production serverless on GCP requires parallel engineering investment across networking (five-layer private data stack: VPC bridging, peering non-transitivity, NAT chaining, private services access, Cloud DNS), identity (build provenance via SLSA attestation, Binary Authorization gate, Workload Identity naming discipline), and secrets (startup fail-fast vs rotation notification-only tension) — each dimension independently mandatory, collectively contradicting the managed-simplicity premise.
