Status: OUT
GCP data management is the highest-complexity operational domain: GCS alone requires four-dimensional engineering (storage class economics, defense-in-depth protection, namespace security, CMEK governance with cross-service blast radius), and this per-service engineering pattern repeats independently across Cloud SQL (triple investment: HA + replicas + private networking), Memorystore (constrained operational model), and Secret Manager (application-level awareness) — with no shared platform abstraction to amortize the complexity.
