Single service comparison

Migration to Huawei

• Map engine/version compatibility, HA topology, replication mode, and backup/restore behavior. For AWS Amazon RDS, the direct Huawei equivalence layer is RDS + GaussDB + TaurusDB; validate feature-by-feature parity for control plane, data plane, and operational behavior before cutover.
• Use a composed Huawei migration pattern where needed: RDS + DRS + DBSS. Treat RDS + GaussDB + TaurusDB 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/serverless runtime, 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.
