Modularization of software is key to handling the inherent complexity of distributed applications like for the Internet of Things (IoT) and provide a flexible environment to evolve applications and manage their deployment effectively. OSGi is a popular framework for dynamic modules for the Java language. Eclipse Concierge provides a clean, small and lightweight implementation of the OSGi core framework specification, specifically tailored to embedded systems and IoT. In this talk, we will cover how to use and deploy the Concierge OSGi framework, demonstrate its advantages based on benchmarks and use cases, and discuss many of the new and upcoming features in the Concierge project such as the OSGi REST interface and Cloud Ecosystems reference implementations
