WSO2 Carbon kernel, the lean, modular, OSGi-based platform, is the base of the WSO2 Carbon platform. It is a composable server architecture which inherits modularity and dynamism from OSGi framework. WSO2 Carbon kernel can be considered as a framework for server development. All the WSO2 products are composed as a collection reusable components running on this kernel. These products/components inherits all the core services provided by Carbon kernel such as Registry/repository, User management, Transports, Caching, Clustering, Logging, Deployment related features.
