The Joyful Journey from Spring Boot to Quarkus

2026-11-20 Voxxed Days holly cumminsQuarkus

Quarkus applications are quick to code, start fast, and require much less hardware than their Spring Boot equivalents. They use less memory, less electricity, and handle much higher load. And, most importantly, they feel great to work with. Fast feedback, great readability, brilliant tools – it’s all about the developer joy.

Can we quantify the financial benefits of switching from Spring Boot to Quarkus? Yes. (Spoiler – it’s good!) In this talk, Holly will explain the architectural differences which make Quarkus fast. Finally, she’ll demonstrate options for getting from Spring to Quarkus quickly and cheaply, for a near-immediate return on investment.
