Single service comparison

Migration to Huawei

• Map detection/prevention policy scope, enforcement points, and response workflows. For Google Cloud Cloud KMS, the direct Huawei equivalence layer is DEW; validate feature-by-feature parity for control plane, data plane, and operational behavior before cutover.
• Use a composed Huawei migration pattern where needed: DEW + CCM. Treat DEW 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 key versions and cryptographic operation requests; Huawei usually bills WAF/CFW/DEW/DBSS/DSC billing by edition, protected assets, requests/events, or scans. Recalculate TCO with peak load, request volume, retention period, and cross-region/interconnect traffic before production migration.
