Recently, because I have used Cloudflare Partner, I feel that CloudFlare has been far behind some domestic CDN streets in terms of CDN. CloudFlare first started operating in 2010, and began to show its prowess in 2011 after successfully resisting attacks by the hacker group LulzSec. Now, CloudFlare can basically be seen on websites that are attacked.
A friend put his corporate website on his cloud host, and the traffic was not large. However, because it was used and was often attacked by CC, the main manifestation was that the IO and CPU increased sharply. Finally, the database hung up and the website became inaccessible. Cloudflare was enabled at the beginning, but the attacker scanned frantically and the defense effect was average.
