OSGi technology is becoming the preferred approach for creating highly modular and dynamically extensible applications. With open source framework implementations like Eclipse Equinox and Apache Felix readily available, there is no better time to move to OSGi technology. However, doing so requires to master the assembly, provisioning, and discovery of the components that make-up your system. Apache ACE, an Apache Incubator project, is a software distribution framework that allows to centrally manage and distribute software components, configuration data, and other artifacts to target systems. We will focus on building and managing OSGi deployments, showing you how to use Apache ACE to bootstrap a framework and deploy to remotely managed systems. Also, we will show how ACE can be used to deploy bundles to an Android based phone.

16. Why?
• Automate deployment
• Insight into who uses what
• History of each system
• Consistent development, tes9ng, produc9on
• Basis for several possible extensions
