OSGi is becoming the technology of choice for modular and dynamic applications in many realms. One of those is the area of device-based software, which brings along its own set of characteristics and challenges. In this session, we will focus on remote management and the software evolution accompanying a large number of devices 'in the field', with ever-changing requirements, deployment scenarios, and device configurations. We'll present the case of a company which uses OSGi as the foundation for their modular device software, and the challenges they faced during their journey from small-scale pilot deployments all the way to large commercial roll-outs.

28. Deployment Admin
• deployment packages
• versioned set of artifacts
• transactional install/update
• fix packages provide deltas
• signing makes them secure
• extensible through resource processors
• AutoConfig defines configuration admin data
