The "portal-first" pattern cripples scale: teams build beautiful UIs (Backstage) over fragile, bespoke automation, leading to inevitable "portal fatigue." Our architectural lesson is definitive: backend-first wins.

This session provides a production-validated blueprint for building a resilient IDP with orchestration and policy as the authoritative core. We prove the theory with a focused demo based on a multi-tenant, 100+ service environment.

We share the operational blueprint (and anti-patterns) to:
1. Showcasing our minimal Platform API/CRD contract that wires ArgoCD, Crossplane, and OPA
2. Detail how policy is authored, bundled, and promoted to prevent composition drift and policy sprawl.
3. Demonstrate the end-to-end golden path

This approach cut infrastructure request lead time from days to minutes, eliminated portal-only snowflake workflows, and reduced GitOps drift incidents by 70%.
