RockCloud vs Alibaba Cloud: choosing a CN2 anti-DDoS CDN
Both accelerate and protect, but the cost structure and barrier to entry are very different. RockCloud prices CN2 routes at roughly half of Alibaba Cloud for comparable specs, bundles terabit-scale DDoS mitigation onto the same path as acceleration, and needs no ICP filing to go live.

| Dimension | RockCloud | Alibaba Cloud |
|---|---|---|
| CN2 route cost | About half the price for comparable specs, with more generous bandwidth | Priced at major-cloud rates; CN2 and cross-border sit in the premium tier |
| CN2 plus mitigation | Acceleration and terabit mitigation on one path, one bill | CDN and Anti-DDoS are separate products, purchased and billed separately |
| Mitigation capacity | 7T+ scrubbing, up to 3 Tbps per IP, business continuity first on overage | Tiered protection packages; exceeding the tier can trigger blackholing |
| ICP filing | Filing-free edge around China, live five minutes after a DNS change | Mainland nodes require a completed ICP filing before onboarding |
| Onboarding and review | Flexible onboarding and documentation, test before you commit | Strict qualification review; some workloads need extra paperwork |
| Cross-border workloads | 3,000+ nodes with bidirectional CN2 — one configuration worldwide | Domestic and overseas configured separately; cross-border is its own product |
| Support | Direct 24/7 engineering contact that stays with you through an attack | Ticket-first support; dedicated engineers need a higher service tier |
Four differences that decide cost and experience
These barely register at low traffic, then amplify quickly once you scale or come under attack.
CN2 cost: the same speed on half the budget
CN2 GIA is the best return path into China and also the most expensive, so many teams settle for ordinary international transit and still stall at peak. We price CN2 at roughly half of Alibaba Cloud for comparable specs and allocate more bandwidth headroom — the same monthly budget buys not just "works" but "still works at peak".
No second purchase just to get protection
In Alibaba Cloud’s catalogue, CDN acceleration and Anti-DDoS are separate product lines: purchased separately, configured separately, billed separately, with traffic detouring between them. We run scrubbing and acceleration on the same request path, so one onboarding gives you CN2 speed and terabit mitigation, on one bill, with one team to call.
Filing-free, live the same day
Mainland nodes require a completed ICP filing first, which is a hard blocker for launches, campaign pages or emergency response. Our edge sits in Hong Kong, Japan, Korea and Singapore — no filing needed — and connects back over CN2, so mainland visitors still get near-domestic speed. A DNS change takes effect in five minutes.
Flexible onboarding, test before you commit
Major clouds apply strict qualification checks and workload restrictions; some industries face lengthy paperwork or outright rejection. Our onboarding is built around what businesses actually need: flexible documentation and a free 24-hour trial on your own real traffic, so you decide after seeing the numbers rather than after paying and filing.
Why customers move over from Alibaba Cloud
The reasons migrating customers cite most often.
- CN2 bandwidth bills got out of hand — the same speed requirement costs about half here, freeing budget for double the headroom.
- They discovered mid-attack that mitigation was a separate purchase — procuring and cutting traffic over takes longer than the attack window.
- ICP filing blocked the launch — new sites, campaign pages and test environments cannot wait for a filing cycle.
- Workload review was rejected or kept asking for more documentation — flexible onboarding means testing with real traffic first.
- Maintaining two configurations for domestic and overseas was tedious — one global footprint with bidirectional CN2 collapses it into one.
Migrating takes four steps
No application changes, gradual rollout, and a DNS record away from rolling back.
Export current config
Export domains, cache rules and origin settings from Alibaba Cloud CDN; we reproduce equivalent semantics in our console.
Run in parallel
Point a low-traffic hostname or one region at us and compare hit ratio, latency and success rate.
Full cutover
Repoint the main CNAME — effective within five minutes. Leave the old config in place so rollback stays instant.
Lock down the origin
Rotate the origin IP and allow only our fetch ranges, closing off direct access to historical addresses.
RockCloud vs Alibaba Cloud FAQ
Savings come from two places. CN2 itself is priced at roughly half for comparable specs with more bandwidth allocated, and you no longer buy a separate Anti-DDoS product because protection ships with acceleration. The exact figure depends on your traffic mix and protection tier — send us your current bill and peak bandwidth and we will produce a direct comparison.
No. Terabit DDoS and CC mitigation come with acceleration on the same request path. There is no separate protected-IP product to buy and no detour between CDN and scrubbing, so when an attack lands you are not procuring and re-routing under pressure — protection is already inline.
Yes. Our acceleration nodes sit in Hong Kong, Japan, Korea and Singapore, forming a filing-free CDN edge that skips the mainland ICP process, then connect back over CN2 so mainland visitors still get near-domestic speed. Add the domain, change DNS, live in five minutes.
Our onboarding is considerably more flexible than the major domestic clouds and most legitimate businesses onboard without friction. Tell us how your business works and start with the free 24-hour trial — run your own real traffic through it, confirm speed and mitigation, then talk contracts.
No. Migration happens at the DNS layer, so you can validate with a low-traffic hostname or a single region before full cutover. Old and new paths run in parallel during the switch and users notice nothing. Keep the Alibaba Cloud config in place — rolling back is just a DNS change.
We keep you online first. A single IP absorbs up to 3 Tbps against 7T+ of network-wide capacity, and if an attack exceeds your tier we raise the scrubbing level to hold the service up, then discuss next steps — rather than blackholing your IP and leaving you to work it out.
