In today's increasingly severe network security environment, "unlimited anti-ddos servers" have gradually become the first choice for enterprises and high-traffic businesses. However, the "unlimited anti-ddos" advertised by many businesses does not mean absolute invincibility, but rather means providing more powerful DDoS anti-ddos capabilities within a certain time and bandwidth range. Usually, it can be judged from the following aspects: Is there a limit on traffic cleaning? Does it provide segmented anti-ddos for different types of attacks such as CC attacks and SYN Flood? Does the anti-ddos rely on high-anti-ddos IP or physical anti-attack capabilities?

　　Infinite anti-ddos Server is not suitable for all applications. It is usually suitable for game servers (such as competitive games), financial payment platforms, e-commerce websites, and high-concurrency Web applications (such as live broadcast and short video platforms)

　　When evaluating server performance, first check the hardware configuration, CPU (multi-core performance affects concurrent processing capabilities), memory (affects data caching and request processing speed), storage (SSD vs. HDD, NVMe storage is faster), bandwidth (whether it is exclusive bandwidth, whether it supports high concurrency)

　　Secondly, there are bandwidth and traffic restrictions. Does the server provide large bandwidth? (High-anti-ddos servers generally provide 100Mbps-10Gbps bandwidth), are there hidden traffic restrictions or peaks? Can it support 24/7 continuous high-traffic attack protection?

　　DDoS attacks are the core challenge of infinite anti-ddos servers. When evaluating, you can use traffic testing tools (such as LOIC, hping3) to simulate DDoS attacks. Observe the server bandwidth and CPU usage to see if malicious traffic can be effectively filtered. Monitor anti-ddos logs to see if the firewall can accurately identify the source of the attack.

　　CC attacks (Challenge Collapsar) are mainly targeted at Web applications. You can use tools such as HULK and GoldenEye to initiate high-concurrency HTTP requests. Observe whether the server crashes or responds slowly due to overload. Test anti-ddos strategies, such as whether WAF (Web Application Firewall) can automatically intercept malicious access.

　　SYN Flood / UDP Flood test. This type of attack mainly consumes server resources. Test method: Run hping3. Simulate a large number of SYN requests to check whether the TCP connection is exhausted. Send large-scale UDP data packets to see if the server is occupied by abnormal traffic. Monitor system logs to see if the firewall can correctly discard invalid traffic.

　　Business stability and compatibility testing are also important. The performance of the anti-ddos server is not only reflected in resisting attacks, but also in ensuring the processing capacity of normal business traffic. Perform stress testing, observe the number of concurrent requests, throughput, and response time, and ensure that normal user access will not be accidentally injured by anti-ddos strategies.

　　Infinite anti-ddos servers are usually paired with security components such as CDN and WAF. When evaluating, you need to pay attention to the CDN cache hit rate. Can it reduce the pressure on the source station? Are WAF rules adjusted intelligently? Does it support advanced anti-ddos strategies such as IP reputation scoring and blacklist management?

　　After being attacked, it is crucial to quickly restore the service of the server. You need to focus on whether the server supports automatic failover? Does the adjustment of anti-ddos strategies affect user experience? Does it provide detailed attack logs and analysis reports?

　　To evaluate the performance of infinite anti-ddos servers, you should not only pay attention to the "anti-ddos ceiling" advertised by the merchant, but also measure traffic cleaning capabilities, anti-DDoS effects, high concurrency stability and other aspects. At the same time, user experience, after-sales support and cost transparency are also important factors that cannot be ignored. Choosing a suitable anti-ddos server requires a combination of theory and practice to ensure that it can truly meet business needs, rather than staying on the propaganda of the word "infinite".
