Single service comparison

Migration to Huawei

• Map ingestion, transformation, query semantics, and governance/metadata dependencies. For Azure Azure AI Search, the direct Huawei equivalence layer is CSS; validate feature-by-feature parity for control plane, data plane, and operational behavior before cutover.
• Use a composed Huawei migration pattern where needed: CSS + DLI + OBS. Treat CSS as the core equivalent capability and use the additional services to cover integration, security, observability, and governance gaps.
• Pricing model difference: Azure usually bills activity/runtime units, compute pools, and stored/processed data; Huawei usually bills DLI/DWS/MRS/CDM runtime or cluster-spec billing plus storage and transfer. Recalculate TCO with peak load, request volume, retention period, and cross-region/interconnect traffic before production migration.
