Serverless promised to remove infrastructure work. So why are we still wiring everything together by hand?

Speaker: Martin Lorenz

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.
