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.
