Jakarta EE 10 and 11 introduce specific profiles, such as the Core Profile , designed for lightweight microservices and native image compilation with GraalVM .
To add cloud-specific features like health checks , metrics , and fault tolerance , developers often pair Jakarta EE with Eclipse MicroProfile.
Migrating to Jakarta EE is often a prerequisite for cloud-native transformation. Legacy applications running on older Java EE servers often rely on rigid, heavyweight application servers that are difficult to containerize. In contrast, the modern Jakarta EE ecosystem supports "thin" servers and executable JARs, which are ideal for containerization.

The next step involves migrating the application to a Jakarta EE-compatible runtime (such as Payara, WildFly, or Open Liberty). This may involve changing dependencies from javax to jakarta namespaces, often facilitated by automated tools like the Eclipse Transformer. This step ensures the application runs on a modern, supported stack that is container-friendly.
This transition was significant for two reasons. First, it shifted governance to an open-source community model, accelerating innovation. Second, it forced a necessary namespace change from javax.* to jakarta.* . While this syntactic change has been a hurdle for migration, it cleared the path for modernizing the specifications. Jakarta EE embraces features essential for cloud-native development, such as better support for microservices (via MicroProfile integration) and lighter runtimes. The "no-constitutional-changes" approach of Jakarta EE 8 paved the way for Jakarta EE 9 and beyond, which laid the groundwork for a natively cloud-ready enterprise platform.
The first step often involves lifting and shifting the existing Java EE application to a cloud environment. While this does not make the application cloud-native, it moves the infrastructure to the cloud, providing immediate scalability benefits. Jakarta EE 10 and 11 introduce specific profiles,
Navigating the Shift: Cloud-Native Development and the Strategic Migration to Jakarta EE
In a cloud-native environment, applications are designed to be loosely coupled, allowing them to be scaled independently and managed dynamically. Traditional Java EE applications, often architected as monoliths deployed on heavy application servers, were not originally designed for this environment. They often required long startup times and consumed significant memory—luxuries that are incompatible with the ephemeral, containerized nature of platforms like Kubernetes. This architectural mismatch created a friction point that necessitated the evolution of the Java enterprise standard.

It uses Jakarta REST for APIs, CDI for dependency injection, and Jakarta Persistence for data management.
For years, Java EE was the gold standard for enterprise computing. However, stewardship under Oracle led to a perception of stagnation, with slow release cycles and a lack of responsiveness to the changing cloud landscape. In 2017, Oracle moved Java EE to the Eclipse Foundation, resulting in the rebranding to Jakarta EE.
