What is Red Hat JBoss EAP

Red Hat JBoss Enterprise Application Platform is a subscription-based/open-source Java EE-based application server runtime platform used for building, deploying, and hosting highly-transactional Java applications and services. It is a middleware solution created by JBoss, now developed by Red Hat.

JBoss EAP has its roots in the open-source JBoss Application Server (JBoss AS). JBoss, originally an independent company, was acquired by Red Hat in 2006. Red Hat rebranded JBoss AS as JBoss EAP, adding enterprise features such as support and patches, and offering it under a subscription model. Over the years, JBoss EAP has evolved significantly, with improvements in scalability, security, and management capabilities, among others.

JBoss EAP plays a crucial role in enterprise applications due to its robustness, scalability, and versatility. It supports a wide range of Java applications, from simple web applications to complex enterprise applications. Its support for various Java standards and specifications, along with its enterprise-grade features, makes it a preferred choice for businesses looking for a reliable and efficient platform for their Java applications.

How Red Hat JBoss EAP Works

Red Hat JBoss EAP operates as a middleware platform, sitting between the operating system and the applications running on it. It provides a runtime environment for Java applications, handling tasks such as transaction management, security, and scalability.

At its core, JBoss EAP uses a multi-threaded, pre-forking architecture. This means it creates a pool of worker threads ready to handle incoming requests, which allows it to efficiently manage resources and maintain high performance even under heavy load.

Architecture of Red Hat JBoss EAP

The architecture of JBoss EAP is modular and flexible. It’s built on a service-oriented architecture (SOA), which means it’s composed of independent services that communicate with each other. This modular design allows for high levels of customization and scalability.

JBoss EAP’s architecture includes several key components, including the JBoss Microcontainer, a lightweight inversion-of-control (IoC) container for managing POJOs (Plain Old Java Objects); and JBoss Modules, a standalone class loading and dependency management system.
