Red Hat JBoss is an enterprise-grade open source application platform published by Red Hat for hosting highly transactional, cloud-ready Java applications. It provides a modular, standards-based runtime environment that supports Jakarta EE and Eclipse MicroProfile, enabling organizations to develop, deploy, and manage scalable applications across on-premise, virtual, and hybrid cloud environments. Key components include Red Hat JBoss Enterprise Application Platform (JBoss EAP), the core runtime for Java applications; Undertow, a high-performance web server; Elytron, a unified security framework; and Infinispan, an in-memory data grid for distributed caching. The platform also supports mod_cluster for intelligent load balancing and integrates with Red Hat OpenShift for containerized deployments, offering centralized management via CLI and web console. This technology is for Java developers, application architects, and system administrators who require a secure, scalable, and standards-compliant runtime for enterprise Java applications in cloud-native and hybrid environments.
