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.
