In this tutorial, our objective is to install WildFly on an unmanaged CentOS 7 server. WildFly is a managed application runtime server and Java software platform used to provision Java applications and services. It is an open-source software which is consistently being improved by its user community. While the WildFly software remains open-source, if paid support is needed, it is provided by Red Hat who currently develops the software (apart from the community forums). Some may be more familiar with WildFly's previous name, which was JBoss AS. RedHat continues to develop its version of this software under the JBoss EAP name.
