Building Community Features with Tencent Cloud: COS, CI, MPS, and CDN Solutions

This article provides a comprehensive guide on building community and feed stream features using Tencent Cloud services. The author analyzes seven key challenges: type compatibility (text, images, audio, video), data security (public/private read/write permissions), data volume scalability, access performance (high QPS requirements), copyright protection (anti-hotlinking, watermarks), loading speed (image/video preview and adaptive streaming), and security compliance (content moderation).

The solution leverages four Tencent Cloud services: Cloud Object Storage (COS) for unified storage of all media types with flexible permission management and horizontal scalability (30,000 QPS per bucket); Cloud Infinite (CI) for image processing including anti-hotlinking, visible/invisible watermarks, and image scaling; Media Processing Service (MPS) for video transcoding, screenshot capture, and content moderation with workflow automation; and Content Delivery Network (CDN) for global content acceleration.

The article demonstrates practical implementations including COS bucket permission configuration, CI watermark parameter concatenation, MPS workflow setup for video transcoding to 480P, and event notification via CMQ message queue. All services are seamlessly integrated, allowing developers to implement complex media handling capabilities through simple URL parameter configuration without code modifications.
