Differences vs Huawei

Volume classes and performance tuning differ.

Migration to Huawei

Map data durability tier, lifecycle policy, encryption, retention, and restore objectives. For AWS Amazon EBS, the direct Huawei equivalence layer is EVS + DSS; validate feature-by-feature parity for control plane, data plane, and operational behavior before cutover.

Use a composed Huawei migration pattern where needed: EVS + CBR. Treat EVS + DSS 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.
