Deep Dive - Recommended Approach
This opinionated deep-dive explains core concepts (for example, architectural layers and monoliths) and gives a practical, recommended way to architect Vaadin applications. If you’re new, this is a good place to start; if you’re experienced, feel free to use whatever patterns work for you.

If you’re evaluating Vaadin, start with When to Use Vaadin. It describes where Vaadin fits, what its server-side approach costs, and where another tool fits better. Then read How a Vaadin Application Works. It explains where a Vaadin application keeps its UI state, and the consequences for latency, threading, and deployment that the other articles build on. Measure Capacity and Test Failover shows how to measure what your views cost in memory and latency, and what users experience when a server stops, before you decide how to deploy. Licensing, Support & Maintenance shows which features are free and which need a commercial subscription, and how Vaadin versions are maintained.
