Merge request retrieval architecture comparing current multi-vendor state with future unified GCP-native design. Current state routes edits, SLA management, and audit logs through multiple channels to a vendor-managed workflow platform, while future state consolidates these flows into a single owning team model with internal platform ownership and Pub/Sub event streaming. The migration eliminates vendor lock-in by replacing external workflow management with GCP's native services, including IAM/Policy controls and event-driven data pipelines. Fork this diagram on Diagrams.so to customize the transition plan, add GCP service specifics, or adapt the pattern for your own platform modernization. This architecture demonstrates best practices for centralizing governance and reducing operational complexity during cloud platform consolidation.
