Introduction to Tencent Cloud Object Storage (COS) and Serverless Cloud Function (SCF) Integration

Overview of the talk: introduces Tencent Cloud Object Storage (COS) and Serverless Cloud Function (SCF), covering COS basics, development history, storage types, and integration with other services.

Describes practical use cases of COS combined with SCF, such as image processing, video transcoding, log analysis, automatic CDN refresh, cross-region disaster backup, and sensitive content detection in online education.

Details a face recognition demo that uses COS buckets to trigger SCF, calls AI interfaces with a few lines of code to extract and compare facial features, and shows how logs display results.

Discusses best practices and limitations: COS triggers SCF only within same region, prefix/suffix filtering, single function binding per bucket event, up to two COS triggers per function, message format passed to SCF, and cost considerations illustrating low monthly expense.

Contrasts traditional server-based development with serverless architecture, highlighting reduced operational overhead, easier scaling, and when traditional VMs may still be preferable.
