Software Developer Mid-Market (51-1000 emp.) 10/31/2019 "Karaf as a container for OSGI project" 2.5/5 What do you like best about Apache Karaf? management of bundles (can easily install new bundle, start, stop) - very useful when running OSGI modules and you want to temporarily stop/add some modules; lightweight independent bundles - no cascade fails Review collected by and hosted on G2.com. What do you dislike about Apache Karaf? takes very long to update (difficult to test, have to maven install and restart the whole thing) logs sometimes are not useful (very often it occurs that some module is failing and you cant understand why until you find out that some requirement is missing, but logs not saying anything about it) updating module that contains hibernate entities requires to restart whole Karaf (otherwise hibernate connection is not recreated) no self load balancing no metrics given outside Review collected by and hosted on G2.com. Recommendations to others considering Apache Karaf: use latest version of karaf check compatibility of OSGI dependencies! do not place hibernate entities in modules that are going to be updated frequently (use separate submodule) if using maven karaf distribution should be the last module in the list! Review collected by and hosted on G2.com. What problems is Apache Karaf solving and how is that benefiting you? We have one big project written in Java that utilizes OSGI pattern. There are more than 70 microservices each containing its own submodules for api, impl, jobs, etc. Karaf is integrated nicely with apache Camel, and that's the library we use mostly. We have 7-8 machines running different groupings of microservices (one - for USSD systems, another - for Target Marketing campaings, etc) - Karaf helps us to manage them efficiently. Containers are lightweight, do not require much memory and are totally independent of each other. Review collected by and hosted on G2.com.

It is very good at making sure the software built is from a known version of every component that is part of it. This is because version parameters are set up for each component in the application, that control the min and max version of that particular component. Review collected by and hosted on G2.com. What do you dislike about Apache Karaf? Initially it is very hard to set up the feature file for the application - which lists all the components and their dependencies. Often would get wiring errors, and the error messages are not very helpful in explaining them. It is a lot of trial and error, and very time consuming. Once set up it works great, until you have to introduce a new component into the mix and then sometimes the fun begins all over again! Review collected by and hosted on G2.com. Recommendations to others considering Apache Karaf: It does what it claims to do but is hard to get your application set up to work with it. Review collected by and hosted on G2.com. What problems is Apache Karaf solving and how is that benefiting you? Controlling versioning of components/libraries that make up a software application. It does make sure that you know EXACTLY what is in each component built with it. Review collected by and hosted on G2.com.
