When using serverless architecture for user experience, several challenges emerge, primarily concerning cold starts that can introduce significant latency for initial user requests, directly impacting perceived performance and user satisfaction. The stateless nature of serverless functions complicates maintaining user session state across interactions, making it harder to design seamless or personalized user journeys. Monitoring and debugging UX issues becomes inherently complex due to the distributed architecture, making end-to-end tracing and identifying performance bottlenecks a significant hurdle. Furthermore, orchestrating numerous micro-functions into cohesive user flows can lead to architectural complexity, potentially hindering rapid prototyping and iteration on user experiences. This environment may also introduce concerns around vendor lock-in, which could limit future design flexibility or migration options for evolving UX strategies. More details: https://infok.com.ua/
