Single service comparison

Migration to Huawei

• Map compute shape/runtime, OS-image behavior, scaling policy, and placement/isolation semantics. For AWS Amazon Machine Images (AMI), the direct Huawei equivalence layer is IMS; validate feature-by-feature parity for control plane, data plane, and operational behavior before cutover.
• Use a composed Huawei migration pattern where needed: IMS + ECS. Treat IMS as the core equivalent capability and use the additional services to cover integration, security, observability, and governance gaps.
• Pricing model difference: AWS usually bills primarily instance/runtime hours (often per-second) plus attached storage and network transfer; Huawei usually bills ECS/BMS/CCE/CCI runtime with EVS, bandwidth/traffic, and optional management add-ons. Recalculate TCO with peak load, request volume, retention period, and cross-region/interconnect traffic before production migration.
