Serverless was supposed to free us from servers – yet here we are, still hand-writing Lambda handlers, wiring up DynamoDB tables, configuring SQS queues, and babysitting API schemas by hand. What if the domain model – your commands, events, and read models, expressed as typed slices – were enough, and the framework generated the rest: the functions, the database, the routing, the GraphQL API, and the infrastructure-as-code to deploy it all?
That’s the claim this talk puts on trial. Instead of a polished pitch, we run it as a live interrogation: a senior, AWS-native engineer who has been burned before plays the skeptic and grills the speaker, question by blunt question. Across a chain of Q&A pairs the whole story gets assembled on stage – and the hard objections get raised and answered in the open rather than dodged. Then the floor is yours for open Q&A.
Come for the answers, stay to ask your own. Best enjoyed if you’ve lived through at least one microservices migration you’d rather forget.
Martin Lorenz is a Vienna-based software architect with more than 30 years of experience and the founder of Reventless. Since 2012 he has designed and built event-sourced, CQRS-based systems across finance, mobility, smart cities, and IoT including a serverless financial data platform on AWS that has run in production since 2019. Reventless distills that experience into a spec-driven, type-safe platform that lets teams focus on their business, not their infrastructure.
