Single service comparison

Migration to Huawei

• Map topology, route propagation, policy order, and failover behavior. For AWS Amazon VPC, the direct Huawei equivalence layer is VPC; validate feature-by-feature parity for control plane, data plane, and operational behavior before cutover.
• Use a composed Huawei migration pattern where needed: VPC + ER + EIP + NAT. Treat VPC as the core equivalent capability and use the additional services to cover integration, security, observability, and governance gaps.
• Pricing model difference: AWS usually bills resource-hours plus processed traffic, request volume, and data 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.
