With Serverless's programmability, precise access control can be implemented based on the request information of each user. Traditional access control is usually composed of matching conditions and matching actions. At the same time, Serverless, as a complete edge programmable environment, offers better scalability than the rule-based configurations and supports rich encryption and decryption algorithms, providing more flexible processing methods.

In scenarios such as major e-commerce promotions or popular concerts/events e-ticketing where users are geographically dispersed, there is usually a sudden surge in access requests and an urgent need for personalized content responses to each user, which requires large-scale real-time dynamic computing and rendering. In these scenarios, centralized services face challenges in handling heavy service loads and complex network conditions, making it difficult to ensure good performance and reliability without complex capacity and network planning. Our Serverless-based solutions leverage the CDN network to obtain only part of state data from the origin server and perform short-term caching and personalized content rendering at the edge, which can distribute request pressure, improve response speed, and enhance user experience.
