One focus of the study is on Jakarta EE 10, which belongs to the Eclipse Foundation, whose proportion of users increased from 17 percent to 34 percent compared to 2023, while Java EE 8 fell from 46 percent to 40 percent. The study doesn’t provide any information about whether Oracle’s new licensing policy is a driving force here. 30 percent of respondents plan to move to Jakarta from their platform (not just Java EE) in the near future. When evaluating these numbers, it is important to note that Eclipse promoted the survey in the Jakarta area.

More cloud, less microservices
25 percent of participants said that more than 80 percent of their Java systems were already running in the cloud (last year: 25 percent). As architecture for Java systems in the cloud, 46 percent chose hybrid architecture, 31 percent chose microservices, and 18 percent chose monolith. This trend is away from microservices, which was 38 percent last year. When it comes to frameworks for cloud-native projects, Spring/Spring Boot leads with 63 percent, ahead of Jakarta (60 percent) and MicroProfile (32 percent).
At 43 percent, AWS is the most popular cloud provider, followed by Azure (35 percent) and GCP (23 percent). In terms of runtime, Tomcat is unbeaten on top with 47 percent, followed by Wildfly (23 percent) and Quercus (20 percent).
