Functions, events, queues, databases, APIs, permissions, and UI components all need to be connected.
And with every change, the event model risks drifting further from the application actually running in production.
What if the event model were all you had to write?
Reventless is an open-source framework that turns a complete event model into a running serverless application—with generated AWS resources, API, and UI.
Not just scaffolding.
Not another layer of boilerplate.
A deployed application generated from a model precise enough for developers and AI agents to understand and extend.
In this talk, we will put that promise to the test with a live online shop.
You will see both sides: the event model that defines the application and the AWS resources created from it.
Then we will ask the question that determines whether this approach really works:
Can the event model stay in sync with the application running in production—automatically?
Come and see how much serverless plumbing can disappear—and what becomes possible when the event model does not merely describe the application, but purely defines it.
Bring your toughest questions. The live discussion is part of the show.
Martin Lorenz is a software architect with more than 30 years of experience and the founder of Reventless. 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. The Open Source framework Reventless distills that experience into a spec-driven, type-safe platform that lets teams focus on their business, not their infrastructure.
László Király is a Vienna-based solution architect, software engineer, and data scientist with more than two decades of experience building software systems and solutions. He has organized the Serverless Vienna Meetup since 2016. Serverless fascinates him for the way it abstracts much of the infrastructure and operational complexity, allowing teams to focus more on business logic, deliver business value faster, and let applications scale naturally with demand. Just as important, however, is the community around it. With the rebooted Serverless Vienna Meetup, László wants to bring people together to openly share experiences, lessons learned, and different opinions—and to look ahead together to a bright future for Serverless.
