Single service comparison

Migration to Huawei

• Map data durability tier, lifecycle policy, encryption, retention, and restore objectives. For Google Cloud Persistent Disk, the direct Huawei equivalence layer is EVS; 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 as the core equivalent capability and use the additional services to cover integration, security, observability, and governance gaps.
• Pricing model difference: Google Cloud usually bills GB-month capacity, operation classes, 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.
