Wildfly Administration
This training course covers the administration of the Wildfly server. We offer this course for Wildfly 5, EAP 6, Wildfly 7 and Wildfly 8/9 versions. You will learn the details of setting up, configuring, and fine-tuning Wildfly application server. Participants will learn the details of Wildfly architecture, steps involved in setting up the application server, basic deployments, production installation and deployment issues, tuning and monitoring, securing the services and clustering.
