Configure and manage clustering, load balancing, and high availability (HA) setups.

Implement real-time troubleshooting for production issues.

Gain clear understanding of L1, L2, and L3 responsibilities in JBoss administration.

Integrate Apache HTTP Server (Apache Web Server) with JBoss EAP.

Configure mod_jk and mod_cluster for load balancing and request routing.

Description

This course takes you from beginner to advanced JBoss EAP administration, providing a complete learning path that is both practical and industry-oriented. We start with the basics, including installation, directory structure, and initial configuration, before moving into real-world administration tasks such as application deployment, module management, logging, and security setup. By progressing step by step, you’ll build a solid foundation and quickly advance into topics that are critical for L1, L2, and L3 administrators.You will learn how to configure standalone and domain modes, tune JVM heap and thread pools for performance, enable SSL for secure communication, and integrate with databases and external services. The course also covers common troubleshooting techniques, including analyzing logs, handling stuck threads, resolving out-of-memory errors, and capturing heap/thread dumps for deeper diagnosis. We will explore garbage collection (GC) tuning strategies and discuss best practices for high availability, clustering, and load balancing in enterprise environments.Whether your goal is to step into an entry-level role (L1), manage day-to-day operations and deployments (L2), or troubleshoot and optimize production systems at an advanced level (L3), this course is designed to give you the skills you need. By the end of the training, you’ll be fully equipped to install, manage, secure, troubleshoot, and optimize JBoss EAP environments in real-world enterprise scenarios.
