How does Cloudflare's DDoS protection work for VPS hosting?

Cloudflare's DDoS protection for VPS hosting employs a multi-layered approach. It utilizes a massive global network to absorb and filter malicious traffic. When an attack occurs, traffic is routed through Cloudflare's network, where sophisticated algorithms analyze the traffic patterns. Suspicious traffic is identified and mitigated before it reaches your VPS. This involves techniques like traffic scrubbing, rate limiting, and connection limits. Cloudflare continuously learns and adapts to evolving DDoS attack vectors, offering dynamic protection against a wide variety of threats. The key is its distributed architecture – the attack is spread across Cloudflare's infrastructure, preventing individual servers from being overwhelmed.
