Service information

AWS Database Migration Service

Shortname: AWS DMS

Huawei equivalent shortnames: DRS

Keywords: replication, database migration, cdc

Differences vs Huawei

Capability scope differs: AWS DMS includes migration modes spanning full load + CDC with engine-specific endpoints, while Huawei DRS separates migration, synchronization, and disaster-recovery task types.
Pricing model differs: AWS DMS pricing is based on provisioned/serverless replication capacity runtime, while Huawei DRS billing depends on task type and runtime with additional source/target resource costs.

Migration to Huawei

Map engine/version compatibility, HA topology, replication mode, and backup/restore behavior. For AWS AWS 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: AWS usually bills instance or serverless capacity runtime plus storage, I/O, 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.
