Single service comparison

Migration to Huawei

• Map topology, route propagation, policy order, and failover behavior. For Azure Azure VPN Gateway, the direct Huawei equivalence layer is VPN; validate feature-by-feature parity for control plane, data plane, and operational behavior before cutover.
• Use a composed Huawei migration pattern where needed: VPN + ER + DC. Treat VPN as the core equivalent capability and use the additional services to cover integration, security, observability, and governance gaps.
• Pricing model difference: Azure usually bills gateway/resource-hours plus processed traffic and outbound transfer; Huawei usually bills EIP/ELB/NAT/ER/DC resource-hours, bandwidth plans, and processed traffic. Recalculate TCO with peak load, request volume, retention period, and cross-region/interconnect traffic before production migration.
