27. Quarkus World Tour 2024 {🤘} Quarkus VS Spring Survey of 26,348 developers: jetbrains.com/lp/devecosystem-2023/java/
28. Quarkus World Tour 2024 {🤘} “We went from 1 min startup times to 400 ms.” RH Press Release Community “We became increasingly worried about resource consumption that Spring Boot was having while being deployed on the Kubernetes cluster… It became increasingly cumbersome to find ways to circumvent the methodology we were using just to squeeze every little bit of performance out of Spring Boot” - Christos Sotiriou DXL Backend Chapter Lead, Vodafone Greece Information Week Community “We could run 3x denser deployments without sacrificing availability and response times of service.” “Quarkus is close to what our developers are already doing with Spring and it’s familiar to them. This is a big benefit” Community “Before we introduced Quarkus, many of our customers had started to look at alternative stacks like Go and node.js to improve performance and efficiency. These customers were weary of selecting a new language and having to hire new developers or retrain their existing Java developers.” - Arijit Mazumdar “There was a low learning curve with Quarkus. It took one of our developers one week to get up to speed on Quarkus and another week to migrate a Spring application to Quarkus.” - Arijit Mazumdar “Quarkus and the Spring API compatibility reduced the migration time and complexity which is critically important for our customers.” - Arijit Mazumdar Community Orgs experiencing Quarkus Joy https://quarkus.io/blog/tag/user-story
29. Quarkus World Tour 2024 {🤘} Orgs experiencing Quarkus Joy “using Spring with AWS Lambda would have been prohibitive because the startup time of Spring in AWS Lambda is too big from my research” - Dennis Baerten “As costs increase, this is when the benefit of using Quarkus will be experienced due to its more efficient use of cloud resources and fast startup time compared to plain Java and Spring Boot” - Dennis Baerten “It took me about 3 days to get familiar with the Quarkus stack” - Dennis Berten, Spring Developer Blog “Some of Payair’s developers had mainly Spring experience, we were concerned that it would be difficult for them to “switch sides”. It turned out that our fear of the unknown was completely unfounded. Quarkus leverages some good old Jakarta EE standards that all Java developers are familiar with. We did not have to learn a bunch of new APIs.” - Hubert Lewandowski “As a long term Spring developer I realized that Spring is slowly becoming the very thing it swore to destroy. The initial premises of Spring (which basically can be summed up as a lightweight alternative to Jakarta EE) are way past the expiry date now. Spring is the undisputed heavyweight champion that can handle everything you imagine but is not your best option for fast and light services. And that applies to Spring Boot as well. - Hubert Lewandowski Blog “When you adopt Quarkus, you will be productive from day one since you don’t really need to learn new technologies.” -TalkDesk Blog “After deploying, we found that Quarkus used about 15% of the CPU, 12% of the memory compared to Spring Boot. So far, we are sticking with Quarkus!” - Sam Dacanay, Lead Software Engineer Blog https://quarkus.io/blog/tag/user-story
