The Supplier Selection List Helps Companies Make Quick Decisions When Renting High-defense Servers In Hong Kong And The United States.

1.

overall decision-making framework: definition of goals and requirements

- clarify business goals (overseas e-commerce, live broadcast, api services, etc.) and peak concurrency estimates.
- evaluate traffic patterns (steady bandwidth vs sudden peaks) and monthly peak bandwidth requirements.
- determine protection requirements (in terms of gbps and pps) and whether cdn is required for acceleration.
- regional priority: hong kong nodes focus on low-latency access to mainland china, and us nodes focus on overseas coverage and cost.
- legal compliance and filing requirements (hong kong generally does not have icp filing but requires compliance, and the united states follows local regulations).
- budget and sla goals: clarify the acceptable monthly cost and protection response time (for example, response within 30 minutes).

2.

list of key technical indicators (supplier evaluation items)

- ddos cleaning capability (gbps) and peak pps processing capability (mpps), it is required to indicate "cleaning bandwidth/port protection".
- network access type: single line/dual line/multi-line, whether to support bgp multi-line and own asn routing.
- bandwidth and traffic billing method (based on peak value/based on 95 peak value/fixed bandwidth).
- host configuration: cpu, memory, storage type (nvme/ssd/hdd) and i/o throughput indicators.
- cdn and load balancing integration capabilities, and whether there is cross-regional back-to-origin optimization.
- operation, maintenance and monitoring: 7x24 response, cleaning strategy transparency, alarm delay and attack and defense log export capabilities.

performance comparison points between hong kong and us nodes

- hong kong: the average delay to mainland china is 20–40ms, which is suitable for services accessed by mainland users.
- united states: optimized for european and american access, latency is generally 80–150ms depending on interstate differences.
- bandwidth costs: the unit price in hong kong is usually higher than that in the united states, and available bandwidth resources are tighter.
- protection network: give priority to suppliers with scrubbing centers in both places to ensure cross-region protection.
- routing quality: test the packet loss rate and jitter of major operators, giving priority to the bgp anycast solution.
- data sovereignty: pay attention to log storage location and backup strategy to meet corporate compliance requirements.

real case: how to deal with large-traffic attacks on cross-border e-commerce

- case background: a cross-border e-commerce company encountered a ddos attack before double 11, with a peak of 120 gbps and 1.2 mpps.
- supplier's response: use us + hong kong dual-point cleaning, scrubbing capacity 200 gbps, 1 minute detection, 10 minutes switching back to the source.
- result: the business only lost packets for a short period of time, and the shopping cart service availability remained at 98.7%.
- lessons and improvements: full-link cdn, port black and white list and connection rate limiting strategy were later added.
- cost and roi: the additional monthly cost increases by about 30%, but the promotion period avoids greater revenue losses.
- recommendations: rehearse beforehand, develop cutover procedures and multi-vendor redundancy.

supplier comparison example table (reference configuration and price)

area	cpu/memory	bandwidth (guaranteed/peak)	ddos cleaning capabilities	monthly price (reference)
hongkong	8 cores/32gb nvme	1 gbps / elastic peak	cleaning 100 gbps/10 mpps	￥3,200
usa	12 cores/64gb nvme	5 gbps / elastic on demand	clean 300 gbps/50 mpps	$450

final decision-making recommendations and implementation steps

- select the main node according to the business geographical division (hong kong gives priority to china access, the united states gives priority to europe and the united states).
- require suppliers to provide attack and defense slas, cleaning processes and historical attack response records.
- conduct a 30-day trial or poc to measure latency, packet loss and cleaning effects.
- configure the back-to-origin strategy and health check of the cdn + high-defense host to avoid single points of failure.
- establish emergency sop: alarm, switching, work order priority and legal team linkage.
- regularly review and adjust bandwidth and protection capacity according to business growth.
