Differences vs Huawei
- Replication workflow and orchestration differ.
Migration to Huawei
- Map data durability tier, lifecycle policy, encryption, retention, and restore objectives. For AWS AWS Elastic Disaster Recovery, the direct Huawei equivalence layer is SDRS + SMS; validate feature-by-feature parity for control plane, data plane, and operational behavior before cutover.
- Use a composed Huawei migration pattern where needed: SDRS + CBR + SMS. Treat SDRS + SMS as the core equivalent capability and use the additional services to cover integration, security, observability, and governance gaps.
- Pricing model difference: AWS usually bills GB-month capacity, request operations, retrieval, and transfer; Huawei usually bills OBS/EVS/SFS/CBR capacity, requests, retrieval/replication, and transfer. Recalculate TCO with peak load, request volume, retention period, and cross-region/interconnect traffic before production migration.
