Single service comparison

Migration to Huawei

• Map API/workflow stages, integration points, pipeline gates, and release controls. For AWS Amazon SNS, the direct Huawei equivalence layer is SMN; validate feature-by-feature parity for control plane, data plane, and operational behavior before cutover.
• Use a composed Huawei migration pattern where needed: SMN + DMS. Treat SMN as the core equivalent capability and use the additional services to cover integration, security, observability, and governance gaps.
• Pricing model difference: AWS usually bills publish/delivery requests and protocol-specific delivery charges; 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.
