CDN Services Comparison Across 4 Major Cloud Providers

Content Delivery Networks (CDNs) are essential infrastructure for delivering exceptional user experiences. AWS CloudFront, Alibaba Cloud CDN, Tencent Cloud CDN, and GCP Cloud CDN are the four leading cloud CDN services, each with distinct strengths in node distribution, caching strategies, security capabilities, and pricing models. This article provides a comprehensive comparison.

Global PoP Distribution

| PoP Dimension | AWS CloudFront | Alibaba Cloud CDN | Tencent Cloud CDN | GCP Cloud CDN | |--------------|---------------|-------------------|-------------------|--------------| | Global PoPs | 600+ | 3200+ | 2800+ | 200+ | | Mainland China | None (requires partner) | 2800+ | 2000+ | None | | Asia-Pacific | Comprehensive coverage | Heavy coverage | Heavy coverage | Major cities | | Americas/Europe | Densest coverage | Major cities | Major cities | Major cities | | Middle East/Africa | Wide coverage | Rapidly expanding | Gradually covering | Limited coverage |

Alibaba Cloud CDN and Tencent Cloud CDN far surpass AWS and GCP in mainland China node count—a core advantage in the Chinese CDN market. AWS CloudFront leads in the breadth of Americas/Europe and global coverage. GCP Cloud CDN has the fewest PoPs but is deeply integrated with Google's global backbone network.

Caching and Performance

| Caching Dimension | AWS CloudFront | Alibaba Cloud CDN | Tencent Cloud CDN | GCP Cloud CDN | |-------------------|---------------|-------------------|-------------------|--------------| | Cache Policies | Cache Policies + Origin Request | Cache config + custom rules | Cache config + custom rules | Cache mode + custom rules | | Dynamic Acceleration | CloudFront dynamic content | DCDN (Full-site Acceleration) | ECDN Dynamic Acceleration | Cloud CDN dynamic content | | Edge Computing | Lambda@Edge / CloudFront Functions | EdgeRoutine | EdgeOne | None | | HTTP/3 | Supported | Supported | Supported | Supported | | Brotli Compression | Supported | Supported | Supported | Supported | | Smart Compression | Gzip + Brotli auto | Gzip + Brotli auto | Gzip + Brotli auto | Gzip auto | | Video Optimization | None (requires MediaPackage) | Video acceleration | Video acceleration | None |

Tencent Cloud CDN excels in dynamic acceleration—its ECDN product is specifically optimized for real-time trading and dynamic API scenarios. Alibaba Cloud DCDN also has deep expertise in dynamic acceleration. AWS CloudFront's Lambda@Edge delivers the most powerful edge computing capabilities. GCP Cloud CDN is the simplest but least feature-rich.

Security Protection

| Security Dimension | AWS CloudFront | Alibaba Cloud CDN | Tencent Cloud CDN | GCP Cloud CDN | |-------------------|---------------|-------------------|-------------------|--------------| | DDoS Protection | AWS Shield (Standard/Advanced) | DCDN DDoS Protection | EdgeOne DDoS Protection | Cloud Armor | | WAF | AWS WAF | WAF integration | WAF integration | Cloud Armor WAF | | SSL/TLS | Free ACM certificates | Free SSL | Free SSL | Managed SSL | | Origin Protection | Origin Access Control | Origin authentication | Origin authentication | Origin Authentication | | Geo Restriction | Supported | Supported | Supported | Supported | | Bot Protection | Bot Control (extra cost) | Bot Management | Bot Protection | reCAPTCHA Enterprise |

AWS Shield Standard provides free L3/L4 DDoS protection for all CloudFront distributions, with Advanced tier offering higher guarantees. Tencent Cloud EdgeOne integrates the most comprehensive security capabilities (DDoS + WAF + Bot protection), performing exceptionally well in Chinese market security scenarios.

Real-Time Audio/Video

| A/V Dimension | AWS CloudFront | Alibaba Cloud CDN | Tencent Cloud CDN | GCP Cloud CDN | |--------------|---------------|-------------------|-------------------|--------------| | Live Streaming | MediaLive + CloudFront | Video Live + CDN | Cloud Live + CDN | No native | | Low-Latency Live | LL-HLS/CMAF | Ultra-low latency live | Low-latency live | No native | | WebRTC Support | None (3rd party required) | Supported | Supported | No native | | Video Transcoding | MediaConvert | Video Transcoding | Cloud Transcoding | No native | | DRM | Supported (Key Service) | Supported | Supported | No native |

Tencent Cloud CDN has the most pronounced advantage in audio/video scenarios, leveraging QQ and WeChat's real-time communication experience for the most mature low-latency live streaming and WebRTC support. Alibaba Cloud CDN also offers rich solutions for live streaming and video transcoding. AWS requires combining MediaLive/MediaConvert services. GCP relies on third-party solutions for A/V.

Analytics and Monitoring

| Monitoring Dimension | AWS CloudFront | Alibaba Cloud CDN | Tencent Cloud CDN | GCP Cloud CDN | |---------------------|---------------|-------------------|-------------------|--------------| | Real-Time Logs | CloudWatch Logs | Real-time logging | Real-time logging | Cloud Logging | | Access Logs | S3 standard logs | OSS logs | COS logs | Cloud Storage logs | | Cache Hit Rate | CloudWatch Metrics | Console real-time | Console real-time | Cloud Monitoring | | Top URLs | Requires Athena query | Console view | Console view | Requires BigQuery | | Custom Reports | QuickSight | DataWorks reports | Data reports | Looker |

Alibaba Cloud and Tencent Cloud CDN provide the most intuitive real-time monitoring and top URL analysis within their consoles, requiring no additional queries. AWS requires CloudWatch, Athena, or QuickSight for similar functionality—more complex to configure but more flexible.

Pricing Comparison

Benchmark: 10TB data egress per month, 10M HTTP requests

| Pricing Dimension | AWS CloudFront | Alibaba Cloud CDN | Tencent Cloud CDN | GCP Cloud CDN | |-------------------|---------------|-------------------|-------------------|--------------| | Asia Egress | $0.114/GB | ~$0.033/GB | ~$0.029/GB | $0.12/GB | | North America Egress | $0.085/GB | ~$0.069/GB | ~$0.062/GB | $0.08/GB | | Europe Egress | $0.085/GB | ~$0.069/GB | ~$0.062/GB | $0.08/GB | | HTTP Requests | $0.0075/10K | ~$0.004/10K | ~$0.003/10K | $0.008/10K | | HTTPS Requests | $0.0100/10K | ~$0.004/10K | ~$0.003/10K | $0.008/10K | | Minimum Fee | None | None | None | None |

In China and the Asia-Pacific region, Tencent Cloud CDN and Alibaba Cloud CDN significantly undercut AWS and GCP on per-GB pricing. In the Americas and Europe, AWS CloudFront and GCP Cloud CDN are more competitive. Tencent Cloud CDN offers the best price-performance in the APAC region.
