How to choose an anti-DDoS CDN: provider comparison
What actually decides cost and experience is rarely the spec sheet. It is whether there is a real CN2 route into China, whether mitigation is a second purchase, whether launch waits on filing, and who picks up the phone at 3am. Here is how RockCloud stacks up against the common alternatives.
Compare provider by provider
vs Alibaba Cloud
About half the CN2 cost, mitigation included
vs Cloudflare
Real CN2 routing, no NS change, native Chinese support
vs AWS
Predictable billing, no learning curve, direct to China
vs SuDun
AI attack detection, observable console, defined SLA
vs Protected Servers
Distributed scrubbing, hidden origin, no blackholing
Four questions worth asking before you sign
Get clear answers to these four and you will rarely choose wrong.
Is there a real CN2 route into China?
For anything serving Chinese users this decides almost everything. Without CN2, peak-hour traffic detours over congested transit and no amount of edge nodes rescues the latency.
Is mitigation a separate purchase?
In many stacks CDN and DDoS protection are different products. You find out mid-attack, and procurement plus re-routing takes longer than the attack window.
Does launch wait on ICP filing?
A filing cycle is a hard blocker for launches, campaigns and emergency response. Filing-free onboarding turns response time from weeks into minutes.
Can you reach a human when it breaks?
Attacks land at midnight and on sale days. A ticket queue and a direct line to an engineer are entirely different experiences.
