== Choosing the Web Flavor

Spring Framework now comes with two different web stacks: xref:web/webmvc.adoc#mvc[Spring MVC] and
xref:testing/unit.adoc#mock-objects-web-reactive[Spring WebFlux].

Spring WebFlux is recommended if you want to create applications that will deal with latency,
long-lived connections, streaming scenarios or if you want to use the web functional
Kotlin DSL.

For other use cases, especially if you are using blocking technologies such as JPA, Spring
MVC and its annotation-based programming model is the recommended choice.
