How do we get our software out on the Internet of Things? Many assumptions in current deployment practices don't hold up. Devices can be occasionally connected, through low-bandwidth networks and are generally outside of direct control. Manually shuffling around binaries is not an option. Apache ACE is an open-source Java provisioning tool tackling such challenges.You can manage Java apps and configs in a modular fashion. The foundations of ACE are OSGi, semantic versioning and reliable communication. Pushing out incremental updates and managing numerous devices becomes possible.

33. Deployment packages
Installation on target
‣ Transactional: retries and rollback
‣ Installation status in audit log
‣ Unreliable networks:
‣ Download instead of stream
‣ Resumable downloads
‣ Custom update strategies

34. ACE Extensibility
‣ Built on modular OSGi architecture
‣ Different repository implementations
‣ Custom update strategies on targets
‣ Multiple topologies (e.g. relay server)
‣ ResourceProcessors for new artifact
types

35. ACE Extensibility
ResourceProcessor
‣ Recognizes your artifact type
‣ Handles installation on target
‣ Upload ResourceProcessor to ACE

36. ACE Extensibility
Configuration ResourceProcessor
‣ Handles XML (MetaType) configs
‣ Placeholders replaced with target tags
...

37. In summary
Modular applications rock!
Modular deployment is worth your while
Apache ACE simplifies IoT deployments
