Possible disadvantages of Apache Karaf

  • Steeper learning curve
    Due to its modular and extensible nature, Apache Karaf can have a steeper learning curve for new users, especially those unfamiliar with OSGi concepts and enterprise middleware.

    Running and managing an Apache Karaf instance can be resource-intensive, especially when dealing with large-scale or highly modular applications. Adequate memory and processing power are required to maintain optimal performance.
  • Complex deployment
    While Karaf can handle complex deployment scenarios, setting it up and configuring it properly can be more involved compared to other simpler solutions. This complexity can increase the initial setup time and effort.
  • Limited community support
    Despite being an Apache project, the community around Apache Karaf might not be as large or active as other popular frameworks, potentially making it harder to find ample resources or immediate support.
  • Dependency management challenges
    Managing dependencies in Karaf, especially when dealing with multiple third-party libraries and their versions, can become cumbersome and lead to conflicts if not handled carefully.

  • Need advice: Java Software Architecture for SaaS startup doing CRUD and REST APIs?
    Apache Karaf with OSGi works pretty nice using annotation based dependency injection with the declarative services, removing the need to mess with those hopefully archaic XML blueprints. Too bad it's not as trendy as spring and the developers so many of the tutorials can be a bit dated and hard to find. Karaf also supports many other frameworks and programming models as well and there's even Red Hat supported... Source: about 4 years ago
