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.
