Microservices promised scalability and agility, but for many teams, they have introduced operational overhead, complex debugging, and fragmented ownership. What if there were a simpler way to achieve modularity without the distributed chaos?

This talk introduces Self-Contained Systems (SCS), an architectural style where each part of the application operates independently, complete with its own UI, business logic, and database. Unlike microservices, SCS architectures minimize cross-service dependencies while preserving the benefits of separation and autonomy.

Through practical examples from a real-world customer project built with Java and Vaadin, you will learn how SCS reduces system complexity, simplifies deployment, and restores end-to-end ownership for teams.

What You Will Learn

• The key differences between Microservices and Self-Contained Systems

• When SCS is a better fit for your architecture and organization

• How to implement SCS using Java and Vaadin

• Strategies for transitioning from distributed sprawl to maintainable independence

Who Should Attend

Developers, architects, and technical leads who want to simplify their architecture while maintaining flexibility and scalability.
