Administering the JBoss® EAP 7.3 and WildFly 18 Application Servers

This course provides hands-on and in-depth coverage on configuring and managing JBoss EAP 7.3 and WildFly servers. It incorporates new server features and all material is current with the new releases. EAP 7.3 is the supported release of the WildFly 18 server. This course is also suitable for other close releases of WildFly (e.g. WF 17,19)

The course is very hands-on, with brief hands-on mini-labs throughout the material which illustrate a topic and help with retention. It also includes numerous larger hands-on labs to dig deeply into a topic.

This course covers all the important administrative tasks that are required to administer this new version of the server. It starts with basic structure, architecture and installation, and moves on to working with the various management tools and deploying applications. Configuration and management of all the important services and subsystems are covered, as is security, domains, and clustering. All management tools are covered, including direct editing of XML configuration files, using the CLI (Command Line Interface), and using the Web-based Management Console. See the list of Sklls Gained and the Detailed Outline for more details.

“Legacy” security, which is still the default configuration, is covered in depth. There is an overview of the new Elytron security subsystem.

The course is focused, informative, and created by experts in the JBoss/WildFly AS. It will demystify the many important capabilities and structure of WildFly server, and leave you well prepared to install, configure, and manage server installations.
