Single service comparison

Map data durability tier, lifecycle policy, encryption, retention, and restore objectives. For Azure Azure Files, the direct Huawei equivalence layer is SFS; validate feature-by-feature parity for control plane, data plane, and operational behavior before cutover.

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