Case Study On The Performance Of Hong Kong High-defense Server 30g During Peak Traffic Periods

this case focuses on the performance evaluation of a hong kong high-defense server with a nominal 30g protection capability under a real site traffic peak and concurrent attacks. the purpose is to help webmasters and operation and maintenance personnel understand the actual effects and purchasing points of a high-defense server.

background description: this site is an e-commerce platform oriented to asia-pacific. the number of concurrent visitors is stable at 3k-5k/minute in normal times. during the promotion period, the traffic naturally increases, accompanied by low-frequency malicious scans and intermittent ddos test traffic. therefore, a 30g-level high-defense server is purchased as a host and anti-attack guarantee.

network architecture: the project uses a high-defense physical server in the hong kong computer room as the main node, and cooperates with domestic and foreign multi-point cdns for edge acceleration. domain names use intelligent resolution to achieve regional distribution. important static resources are cached by the cdn, and dynamic requests are received and processed by the high-defense server.

attacks and traffic peaks: in the first hour of the promotion, the real access traffic surged to 8 times the daily peak value, and the instantaneous bandwidth entrance and exit peak was close to 22gbps. at the same time, it encountered continuous syn flooding and udp traffic detection, which lasted about 20 minutes. then the attack turned to more scattered small packet detection.

high-defense capability performance: the nominal 30g high-defense server performed robustly in this incident. intrusion traffic was identified in real time by the protection layer and directed into the cleaning pool. automatic black and white lists and baseline behavior analysis maintained the pass rate of legal traffic above 98%, and there was basically no perceived interruption to the business.

traffic cleaning and policies: the high-defense platform cleans traffic through comprehensive strategies such as threshold identification, attack signature matching, and deep packet inspection. it temporarily blocks abnormal ips and synchronizes them to firewall rules. it also combines rate limiting and session retention to reduce accidental killings.

effect of cooperation with cdn: cdn takes on most static resource requests at the edge, effectively reducing the pressure on the origin site. the linkage between cdn and high-defense allows high-bandwidth attacks to be absorbed at the edge or cleaned at the access layer, and dynamic requests are further protected at the high-defense server layer.

latency and user experience: although the cleaning process will introduce a small amount of additional delay during the peak period, through intelligent routing and nearby access strategies, the average user page response time only increased by about 120ms, and the e-commerce core transaction process did not show a significant increase in failure rate.

resources and concurrent processing: the server is reasonably configured with multi-core cpus and large-capacity memory, and enables connection pools and asynchronous processing mechanisms. preemptive resource scheduling ensures the priority of key services in high-concurrency read and write scenarios, and the database only withstands necessary dynamic writes.

monitoring and alarm response: after the event is triggered, the operation and maintenance team intervenes within 2 minutes through real-time monitoring panels and multi-level alarms (sms messages, phone calls, work orders), adjusts cleaning strategies and traffic allocation, and shortens the window of impact of attack peaks on the business.

failure and recovery measures: in extreme cases, this solution supports switching to a nearby backup computer room and enabling traffic mirroring and load sharing. automated scripts can complete dns switching and rollback in a short time, ensuring that the business is restored to stability in the shortest time.

security enhancement suggestions: combining multi-layered protection such as waf rules, api current limiting, verification codes, session anomaly detection, etc. can further reduce the attack surface. it is recommended to conduct secondary verification of sensitive interfaces and carry out special identification strategies for robot behavior.

procurement and cost considerations: 30g high-defense products cost more than low-defense products, but for high-risk industries (finance, e-commerce, games), bandwidth and cleaning capabilities are directly related to business availability. it is recommended to select the appropriate protection level and evaluate bandwidth elasticity based on peak traffic and attack probability.

deployment suggestions: when purchasing, pay attention to the provider's upstream backbone, cleaning center topology, bgp line redundancy, computer room level, and emergency response slas. if necessary, a customized sla can be signed with the provider to ensure cleaning and bandwidth protection during the attack period.

purchase recommendation: if you need to deploy a high-defense host or high-defense vps in hong kong, it is recommended to choose a service provider with a mature cleaning platform, 24/7 operation and maintenance support, and multi-line bgp capabilities. also confirm whether it supports on-demand elastic expansion of bandwidth to cope with emergencies. if necessary, purchase supporting cdn and waf services.

case conclusion: this 30g high-defense server performed well overall under real peaks and attacks. it was able to identify and filter most malicious traffic in a short time, ensuring the stable operation of key businesses. reasonable architecture and operation and maintenance response are the keys to achieving high-defense effectiveness.

if you are planning to purchase a high-defense server or need one-stop hosting, vps, domain name, and cdn services, you can contact a professional supplier to conduct a solution evaluation and trial cleaning test to ensure sufficient anti-risk capabilities during peak traffic periods.
