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.
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.
Features
Wildfly supports a number of features:
- Jakarta Persistence (JPA)
- Jakarta Enterprise Beans (EJB)
- Distributed transactions - Wildfly implements the Jakarta Transactions API (JTA).
- Representational state transfer (REST) services.
- WebSocket
- Clustering - Wildfly uses Infinispan as its distributed cache system
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.
