Differences vs Huawei
- Capability scope differs: Azure DMS supports classic offline and premium online migration modes, while Huawei DRS offers migration/synchronization/DR task modes with different engine matrices.
- Pricing model differs: Azure DMS classic Standard tier is free and Premium is billed hourly after its free period, while Huawei DRS is billed by task/resource mode plus related infrastructure/network charges.
Migration to Huawei
- Map engine/version compatibility, HA topology, replication mode, and backup/restore behavior. For Azure Azure Database Migration Service, the direct Huawei equivalence layer is DRS; validate feature-by-feature parity for control plane, data plane, and operational behavior before cutover.
- Use a composed Huawei migration pattern where needed: DRS + RDS + GaussDB. Treat DRS as the core equivalent capability and use the additional services to cover integration, security, observability, and governance gaps.
- Pricing model difference: Azure usually bills vCore/DTU or serverless runtime plus storage, backup, and transfer; Huawei usually bills RDS/GaussDB/DDS runtime or DRS task billing plus storage, backup, and transfer. Recalculate TCO with peak load, request volume, retention period, and cross-region/interconnect traffic before production migration.
