Tencent Cloud has rapidly expanded its serverless offerings, leveraging its gaming and social media expertise to create a comprehensive serverless ecosystem. With roots in handling massive-scale applications like WeChat and QQ, Tencent Cloud brings unique insights to serverless computing. This guide explores Tencent Cloud’s serverless ecosystem and how it powers modern applications.

What is Serverless Computing?

Serverless computing allows developers to focus on code while the cloud provider manages infrastructure, scaling, and maintenance. Tencent Cloud’s serverless ecosystem includes:

Serverless Cloud Function (SCF): Function as a Service platform
Serverless databases: Auto-scaling database services
Serverless containers: Kubernetes without node management
Event-driven architectures: Integration with Tencent Cloud services
