Serverless Vienna Reboot: Recap & Reventless

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. Isn’t „generated infrastructure“ just a starter template you immediately hand-edit? Isn’t this lock-in by another name? Identical code in-process and on Lambda — haven’t we heard that before? Why ReScript? Aren’t these „slices“ just microservices reborn? And isn’t event sourcing a UX nightmare?

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 micro-services migration you’d rather forget.
