Differences vs Huawei

  • Disk tiers and bursting behavior differ.

Migration to Huawei

  • Map data durability tier, lifecycle policy, encryption, retention, and restore objectives. For Azure Azure Managed Disks, 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: Azure usually bills GB-month capacity, transaction counts, retrieval/snapshot, 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.
