Jakarta EE
Commonly used in Enterprise Computing, Cloud Computing
Jakarta EE is an open-source platform that serves as the future evolution of the Java Platform, Enterprise Edition (Java EE). It provides a set of specifications and APIs for building robust, scalable, and portable enterprise applications using Java, with a focus on modern cloud-native development.
How It Works
Jakarta EE is built around a modular architecture that includes a variety of specifications such as servlets, JavaServer Faces (JSF), Enterprise JavaBeans (EJB), and Java Message Service (JMS). These components are implemented by compatible application servers, which provide the <a href="https://www.ituonline.com/it-glossary/?letter=R&pagenum=4#term-runtime-environment" class="itu-glossary-inline-link">runtime environment for deploying and managing enterprise applications. The platform promotes standardization, ensuring that applications developed with Jakarta EE can run on any compliant server, facilitating portability and interoperability.
It leverages a set of APIs and container-managed services that simplify the development of enterprise features like transaction management, security, persistence, and messaging. Developers write code against these specifications, and the application server handles the underlying complexity, enabling focus on business logic rather than infrastructure concerns. The open-source nature of Jakarta EE encourages community-driven innovation and regular updates aligned with modern cloud-native practices.
Common Use Cases
- Developing scalable web applications that can run on multiple cloud platforms.
- Creating microservices architectures with lightweight Jakarta EE components.
- Building enterprise-grade APIs for integration with other systems and services.
- Implementing secure transaction processing for financial or healthcare applications.
- Modernising legacy Java EE applications to be cloud-ready and container-friendly.
Why It Matters
Jakarta EE is essential for IT professionals involved in enterprise application development, especially those targeting cloud environments. Its open-source model promotes transparency, community collaboration, and rapid innovation, making it a vital platform for modern Java enterprise solutions. Certification candidates and developers benefit from understanding Jakarta EE's specifications and best practices, as these skills are highly valued in roles requiring scalable, portable, and cloud-native Java applications. As enterprises increasingly migrate to cloud infrastructures, expertise in Jakarta EE positions developers to build and maintain future-proof enterprise systems.
