Differences vs Huawei

  • Subscription delivery semantics differ.

Migration to Huawei

  • Map ingestion, transformation, query semantics, and governance/metadata dependencies. For Google Cloud Google Cloud Pub/Sub, the direct Huawei equivalence layer is DIS + DMS; validate feature-by-feature parity for control plane, data plane, and operational behavior before cutover.
  • Use a composed Huawei migration pattern where needed: DataArts Fabric + CDM + DLI. Treat DIS + DMS as the core equivalent capability and use the additional services to cover integration, security, observability, and governance gaps.
  • Pricing model difference: Google Cloud usually bills runtime/processing units, processed data, and storage; Huawei usually bills DLI/DWS/MRS/CDM runtime or cluster-spec billing plus storage and transfer. Recalculate TCO with peak load, request volume, retention period, and cross-region/interconnect traffic before production migration.
