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.
  • Resource intensity
    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

  • Replacing Kubernetes with Systemd
    I deployed CNPG (https://cloudnative-pg.io/ ) on my basement k3s cluster, and was very impressed with how easy I could host a PG instance for a service outside the cluster, as well as good practices to host DB clusters inside the cluster. Oh, and it handles replication, failover, backups, and a litany of other useful features to make running a stateful database, like postgres, work reliably in a cluster. - Source: Hacker News / about 1 month ago
  • Operational Considerations for Managing Stateful Workloads
    If this setup seems complex, that's because it is. Especially if you consider that you might have multiple replicas which might also need to get scheduled on new nodes etc. In many ways, it resembles the Tower of Hanoi puzzle—careful sequencing is key. That's why it's better to leverage some tools to help you out. Especially with Postgres, there is an operator that will act as Controller (cloudnativePG) that will... - Source: dev.to / 4 months ago
