Apache Karaf OSGi Application Training is a practical, hands-on program designed to equip learners with the skills required to build, deploy, and manage modular enterprise applications using the OSGi framework and Apache Karaf runtime. This training focuses on OSGi architecture, bundle lifecycle management, service-oriented modular development, Karaf container setup, feature deployment, and application monitoring. Participants will gain real-world experience in building highly modular, dynamic, and scalable Java-based applications.

Participants will gain strong expertise in OSGi and Apache Karaf, enabling them to build modular, dynamic, and scalable enterprise Java applications with efficient service management and deployment strategies.

• Java Developers and Software Engineers
• Backend and Enterprise Application Developers
• System Architects and Solution Designers
• Middleware and Integration Engineers
• IT Professionals working on modular application frameworks

• Strong understanding of Core Java programming
• Basic knowledge of OOP concepts and design patterns
• Familiarity with Maven or build tools is helpful
