Vaadin Create 2025
Agenda Day 1

The landscape for development tools is changing faster than ever, and a lot has happened in the past year. Let's take a look at the most interesting new features in Vaadin Copilot, AI-driven and traditional, including some of the top wishes from last years' Create – and maybe a surprise or two.

Starting a new software project comes with a flood of considerations—from tech stacks and team structure to budgeting and beyond. And for teams not starting from a clean slate, modernization adds another layer of complexity. We surveyed over 1,000 Java professionals to understand how they’re approaching these choices today.

A deep dive into how to deal with UI state that is explicitly declared as reactive signals. What does it mean to share state between components or even between users? How do you avoid a mess of infinite loops when components are reactively updating themselves?

Microservices are a popular approach to building modern software, offering scalability and flexibility. But for many teams, they come with challenges like increased complexity, difficult debugging, and managing too many small services.

In this talk, I'll introduce an alternative: Self-Contained Systems (SCS). Unlike microservices, SCS allows each part of your application to operate independently with its UI, logic, and database, simplifying both development and deployment.

You'll learn why SCS can be a better fit for many projects, how it reduces the complexity of distributed systems, and when it makes sense to use this approach over microservices. Based on my current customer project I’ll show how to modernize an ERP system based on self-contained systems with Vaadin.

Did you know that Vaadin 8 has sufficient capabilities to make your applications accessible? Tatu will show you how. Also he will be sharing the latest news from Vaadin 7 and 8 extended maintenance and how the updates will help to maintain your applications.
