Building scalable Spring applications often depends on choosing the right approach to asynchronous programming. In the past, developers relied heavily on Reactive libraries and WebFlux to handle concurrency and scalability, but do those choices still make sense today? This session takes a practical look at how asynchronous programming in Spring Boot has evolved, comparing older reactive models with modern best practices.

Attendees will explore current tools and design patterns for creating efficient, responsive Spring applications, and learn when (and when not) to use reactive approaches in today’s Spring ecosystem. The talk provides a clear understanding of how to select the right async strategy for your workloads while keeping code maintainable and production-ready.

What You Will Learn

• How asynchronous programming in Spring has evolved over time

• When to use (or avoid) Reactive and WebFlux in modern Spring applications

• Best practices for building scalable and efficient Spring Boot systems

Who Should Attend

Java developers, Spring engineers, and software architects aiming to improve the scalability and responsiveness of Spring-based applications.
