Red Hat JBoss Enterprise Application Platform (JBoss EAP) is an open-source, Java-based application server platform offered by Red Hat. It provides a robust, enterprise-grade environment for building, deploying, and managing Java applications, particularly those utilizing Jakarta EE (formerly Java EE) specifications.

Key aspects of JBoss EAP:

• Modernization:

  Facilitates the modernization of traditional Java EE applications to leverage technologies like cloud, containers, and microservices, often in conjunction with platforms like Red Hat OpenShift.

• Management capabilities:

  Offers powerful management tools, including an updated management console, and supports both standalone server mode for individual instance management and managed domain mode for managing groups of instances from a central point.

• Deployment flexibility:

  Can be deployed in various environments, including on-premise, public clouds (Azure, AWS, Google Cloud), and container platforms like Red Hat OpenShift.

• Commercial support:

  As a Red Hat product, JBoss EAP comes with commercial support and maintenance, making it suitable for organizations requiring enterprise-level assistance.

• Enterprise-grade:

  Designed for production environments, offering features like security, performance, scalability, and high availability.

• Jakarta EE certified:

  Supports leading Java standards and specifications, including Jakarta EE core profile and Java SE. 

Relationship with WildFly:

JBoss EAP is built from the WildFly project, which is an open-source, community-driven application server. WildFly serves as an incubator for new features and technologies, which are then tested and refined before being integrated into a commercially supported release as JBoss EAP. This means WildFly often includes newer features, while JBoss EAP provides a stable, supported platform for enterprise applications.
