WildFly is written in Java and implements the Java Platform, Enterprise Edition (Java EE) specification.{{sfn | Stancapiano | 2017 | loc=Chapter §1 Introducing Java EE and Configuring the Development Environment | pp=8-9}} It runs on multiple platforms.

== Origin == In 1999, Marc Fleury started a free software project named ''EJB-OSS'' (stands for ''Enterprise Java Bean Open Source Software'') implementing the EJB API from J2EE (Java 2 Enterprise Edition). Sun Microsystems asked the project to stop using the trademarked ''EJB'' within its name. ''EJB-OSS'' was then renamed to ''JBOSS'', then ''JBoss'' later.{{Sfn | Jamae | Johnson | 2010 |p = 4}}
On November 20, 2014, JBoss Application Server was renamed WildFly. The JBoss Community and other Red Hat JBoss products like JBoss Enterprise Application Platform were not renamed.<ref>{{cite web | url=http://www.wildfly.org/faq/ | title=Frequently Asked Questions | website=WildFly | access-date=2013-04-23 | url-status=dead | archive-url=https://web.archive.org/web/20130928204119/http://www.wildfly.org/faq/ | archive-date=2013-09-28 }}</ref>

== Licensing and pricing == JBoss EAP itself is open source, but Red Hat charges to provide a support subscription for JBoss Enterprise Middleware. Before November 2010 JBoss was licensed as annual subscription in bundles of 4 and 32 CPU sockets. As of November 2010 the licensing changed and all cores on the system are now counted. The core bundles licensing is available for 2, 16, and 64 cores.
