Yan Cui is a UK-based AWS Hero and one of the most authoritative independent voices on serverless architecture on AWS — particularly Lambda, the surrounding event-driven stack (EventBridge, SQS, Step Functions), and the operational patterns for production serverless systems. He runs theburningmonk.com and consults extensively on serverless architecture.
His CourseFlix listing carries Production-Ready Serverless — a comprehensive treatment of building production serverless systems on AWS: the architectural patterns, the testing strategies for serverless code, observability, the cost-and-cold-start trade-offs, and the engineering decisions for serverless at scale.
Material is paid and aimed at engineers building production serverless systems. For broader content, see CourseFlix's AWS category page.
