Designing User Workflows and Request Routing in Serverless Apps

Building modern applications with serverless architecture requires a shift in how we handle user journeys, persistent sessions, and traffic routing. Traditional server-based state management doesn't work in ephemeral, stateless environments like AWS Lambda. This text-based course guides you through the fundamental patterns of serverless request routing and state management. You will learn how to design secure user workflows, route requests efficiently, and manage session states without compromising on speed, cost, or security. What you'll learn: - Understand the fundamentals of stateless serverless architectures and how they impact user sessions. - Configure request routing using API Gateway and Lambda function URLs. - Implement secure session management patterns using external data stores like DynamoDB. - Apply modern token-based authentication to secure user workflows without state bottlenecks. - Optimize Lambda execution costs by designing efficient routing architectures. - Practice designing end-to-end user flows through structured written exercises and architectural scenarios. You will start with core concepts of statelessness and request lifecycles before moving on to step-by-step routing configurations and state storage strategies. The course wraps up with practical architectural patterns for secure, production-ready serverless user workflows. This course is designed for beginner cloud developers, software engineers, and system architects looking to transition to serverless designs. No prior serverless experience is required, though a basic understanding of web application concepts is helpful. Start reading today to master the core patterns of serverless application design.
