With UCloud's timely and professional support, website availability is guaranteed 24/7. Supports primary/backup origin configuration with continuous origin health checks and automatic failover to the backup origin when the primary fails. Supports origin request merging to reduce back-to-origin bandwidth under high concurrency.
Superior PerformanceDelivers outstanding acceleration performance, reliably supporting access and downloads of large volumes of images, audio, and video files, and handling massive concurrent user requests with ease.
Fully Integrated with Cloud StorageIntegrates with object storage UFile to solve mass data storage and distribution challenges. Supports storing origin data in UFile with elastic on-demand scaling, enabling faster and more convenient content delivery at lower cost.
Low Cost, Easy to ScaleAchieves the same or better results at lower cost. Resources can be elastically scaled up or released on demand with pay-as-you-go billing. Feature-rich with open APIs for easy business expansion.
Use Cases
Multiple Use Case SupportSmall file acceleration: supports static file acceleration for web pages, including images and small file types such as shtml, html, htm, js, and css. Large file download acceleration: supports game installation and update download acceleration for large file types such as exe, apk, 7z, and zip, with large file compression and range download support. Audio/video on-demand acceleration: supports acceleration for all types of audio and video files including m3u8, ts, flv, mp4, avi, and hls formats, with video seek support.
- Security Protection
UCDN employs multi-layered security measures including Referer and UA validation, IP allowlists/blocklists, and encrypted timestamp hotlink protection to block unauthorized requests and prevent resource exhaustion or cost overruns. Can be combined with DDoS protection to defend against network-layer and transport-layer DDoS attacks. Paired with UMON resource monitoring for automatic detection of service anomalies.
- Monitoring and Data Analytics
Provides minute-level bandwidth and request count data, as well as monitoring data broken down by province and ISP. Offers valuable insights for analyzing client behavior and evaluating service quality.
- Simple to Use with Open APIs
Supports custom hotlink protection, cache policies, and HTTP response headers. Open API interfaces provide functions including service activation, content refresh, monitoring data retrieval, and distribution log downloads, making it easy for developers to access data programmatically.
