Transitioning from BFF to Serverless BFF (SFF) Architecture

This presentation discusses the evolution of BFF (Backend for Frontend) architecture to a Serverless For Frontend (SFF) model. It addresses pain points in traditional BFF implementations, such as high operational costs and slow deployment cycles, and demonstrates how Serverless functions can resolve these issues. The content covers business background challenges, core BFF architecture components, SFF implementation strategies, and technical optimizations.

The BFF architecture initially solved issues like business orchestration, field conversion, and personalized data handling for front-end applications. However, as business demands grew, traditional BFF faced scalability and maintenance challenges. The SFF approach replaces BFF with serverless functions, enabling dynamic code deployment and reducing infrastructure overhead. Key components include a developer platform for function management and a FaaS layer for executing functions.

Implementation details focus on process-based execution using Node.js, process isolation via VM2 modules, and resource control through CGroup. The Serverless BFF model offers advantages like second-to-second deployment, reduced operational costs, and improved team efficiency. The presentation concludes with a summary of benefits and future directions for front-end architecture.
