Java Experiences Renaissance

September 16, 2021

The Eclipse Foundation released results of the industry’s most prominent survey for technical insights into enterprise Java, the 2021 Jakarta EE Developer Survey. The results definitively showcase significantly increased growth in the use of Jakarta EE 9 and interest in cloud native Java overall. The 2021 Jakarta EE Developer Survey Report is available to download on the Jakarta EE website.

“Since the ‘big bang’ move to the jakarta namespace with Jakarta EE 9, enterprise Java has been experiencing something of a renaissance, ” said Mike Milinkovich, executive director of the Eclipse Foundation. “With the plan for Jakarta EE 10 already formalized and the continued growth in the use of Jakarta EE 9, the cloud native future of open source enterprise Java has never looked brighter.”

“We are very happy to see that the Jarkata EE developer survey findings demonstrate continued success and growth of the Jakarta EE platform,” said Tom Snyder, VP of Engineering, Enterprise Cloud Native Products at Oracle. “We are quite pleased to see the most requested feature is support for Kubernetes. We hope to bring the experience and expertise we've gained delivering and supporting Oracle Verrazzano Enterprise Container Platform to benefit technology and feature development of Jakarta EE Platform and MicroProfile. With Verrazzano, users can easily model, manage, secure, and maintain their enterprise applications developed in Jakarta EE using a wide range of platforms and frameworks running on premise, or in the cloud.”

The objective of this survey, now in its fourth year, is to help Java ecosystem stakeholders better understand the requirements, priorities, and perceptions of enterprise developer communities. The survey also sought to help the Java ecosystem gain a better understanding of how the cloud native world for enterprise Java is unfolding and what that means for their respective strategies and businesses. Conducted from April 6 to May 31, 2021, 940 individuals participated in the survey. Java EE 8, Jakarta EE 8 and Jakarta EE 9 have now seen 75% adoption among respondents.

Additional key findings from this year’s survey include:

Spring/Spring Boot continues to be the leading framework for building cloud native applications (60%), with its share increasing by 16 points (60% in 2021 up from 44% in 2020).

Jakarta EE is emerging as the second place cloud native framework with 47% usage in this year’s survey.

MicroProfile adoption has increased to 34% (vs 29% in 2020).

The popularity of microservices holds steady with a nominal increase, with the usage of the microservices architecture for implementing Java systems in the cloud increasing since last year (43% in 2021 vs 39% in 2020).

Over 48% of respondents have either already migrated to Jakarta EE or plan to within the next 6-24 months.

As part of the report on the survey’s findings, the Eclipse Foundation has also incorporated specific recommendations for both enterprises and technology vendors and their respective enterprise Java strategies. These include recommendations related to technology migration, application portability, balancing traditional enterprise applications with cloud native applications and more.

The Jakarta EE community welcomes contributions and participation by all interested parties. As the Jakarta EE Working Group continues to build towards the release of Jakarta EE 10, including new cloud native functionality, this is the ideal time to join the community and have your voice heard.
