Single service comparison

Map API/workflow stages, integration points, pipeline gates, and release controls. For AWS Amazon SQS, the direct Huawei equivalence layer is DMS; validate feature-by-feature parity for control plane, data plane, and operational behavior before cutover.

Use a composed Huawei migration pattern where needed: DMS + SMN + EventGrid. Treat DMS as the core equivalent capability and use the additional services to cover integration, security, observability, and governance gaps.

Pricing model difference: AWS usually bills request/message volume and throughput/storage where applicable; Huawei usually bills CodeArts/APIG/DMS runtime or request volume plus artifact/storage usage. Recalculate TCO with peak load, request volume, retention period, and cross-region/interconnect traffic before production migration.
