How Cloudflare's Architecture Allows Us to Scale to Stop the Largest Attacks

Cloudflare's architecture is designed to withstand large-scale DDoS attacks, unlike legacy DNS and DDoS mitigation services that rely on expensive boxes and bandwidth. Instead of using dedicated mitigation hardware, Cloudflare uses software that distributes load geographically across its network of servers. This approach allows the company to cost-effectively continue investing in its network and efficiently handle large attacks by spreading the load across thousands of servers. Additionally, since every core in every server can help mitigate attacks, each new data center improves the ability to stop attacks near their source.
