Alibaba Cloud vs Tencent Cloud: Which CDN Should You Choose?
Last year, a client planning to expand overseas asked me: "Alibaba Cloud and Tencent Cloud both look great on paper. Nodes, features, pricing all seem similar. How do I actually choose?"
I broke down their business requirements and the answer became obvious.
This is the most common CDN selection problem: looking at spec sheets instead of business scenarios. You end up picking what "everyone says is good."
01 Start with These Three Questions
Before comparing CDN providers, answer these three questions — they're more useful than any spec sheet.
Where are your users? Alibaba Cloud CDN has 3200+ global nodes . Tencent Cloud CDN has 2300+ nodes . Both are solid. Choose based on where your users are.
What content are you accelerating? Static resources (images/CSS/JS) need high cache hit ratios. Dynamic content (APIs) needs route optimisation. Video/live streaming needs protocol support and low buffering rates. Different business types have completely different CDN requirements.
What's your budget and traffic volume? Pay-as-you-go works for fluctuating traffic. Bandwidth plans work for stable traffic. Large traffic volumes can consider 95th percentile billing, small volumes are more flexible with pay-as-you-go.
02 Node Coverage & Performance
Alibaba Cloud CDN: 3200+ nodes, 180 Tbps bandwidth capacity . 2300+ nodes in mainland China covering 31 provinces . 900+ nodes in Hong Kong, Macau, and overseas across 70+ countries . Deeply integrated with Alibaba Cloud's ecosystem, verified by Double 11 traffic.
Tencent Cloud CDN: 3200+ nodes, 160+ Tbps bandwidth capacity . 2300+ nodes in mainland China with 100% provincial coverage . 900+ nodes in overseas regions across 70+ countries . Strong in Southeast Asia, with deep integration with WeChat and gaming ecosystems.
Selection advice:
Users mainly in China → Alibaba's domestic nodes are slightly denser
Users in Southeast Asia → Tencent Cloud has proven advantages
Global coverage → test both with actual traffic
03 Pricing Models
Both use similar billing structures.
Pay-as-you-go: Suitable for fluctuating traffic. Alibaba's tiered pricing ranges from ¥0.24/GB to ¥0.18/GB depending on volume.
Bandwidth plans: Suitable for stable traffic. Monthly peak bandwidth billing.
Cost optimisation tips:
Off-peak traffic plans
Enable smart compression (Gzip/Brotli) to reduce transfer volume
Optimise caching policies to reduce origin fetches
04 Ecosystem & Integration
If your business is deeply tied to a specific cloud provider, choose that provider's CDN for smoother integration .
Alibaba Cloud: E-commerce/overseas expansion priority — proven by Double 11, integrated with Alibaba's ecosystem
Tencent Cloud: Video/live streaming/social priority — strong video tech, WeChat and gaming ecosystem
05 Test Before You Choose
Don't just read spec sheets. Apply for trials from both providers and run side-by-side tests with real business traffic.
Key metrics to track:
Time to First Byte (TTFB)
Cache hit rate
Origin fetch latency
User experience from different regions
The Bottom Line
There's no single "best" CDN — only the one that fits your business.
That overseas expansion client ended up choosing Alibaba Cloud CDN because their users were mainly in China and the domestic coverage and pricing worked better.
