Usage of Enterprise OSGi inside Siemens:
Siemens Communications, Enterprise Systems
HiPath product family
SCA and OSGi integration
e.g. Service Delivery Platform
e.g. Usage of Enterprise OSGi parallel to JEE
Pervasive Computing
e.g. Daidalos EU project

SCA and OSGi
Our InterestOSGi Binding
OSGi implementation type
OSGi-based SCA container
What’s missing?SCA based component model (e.g. remote services
versus components)
Improved Lifecycle and Enterprise suitable Dependency Management
Inter-Container Communication
Service Discovery

extension of OSGi service model
distribution over multiple containers
distinction of service vs component
support for runtime AOP, e.g. interceptors, proxies
enterprise style Declarative Services
public vs private properties
better integration with CAS
late injection of optional dependencies
declared object dependencies
availability of service instances because of changes to properties or -> modification of existing DS specification

multiple containers
inter container communication
integration into existing and new ESBs
support for different communication patterns, e.g. request-reply, request-multiple-reply, publish-subscribe, push-poll
distributed (scaled) service registry
distributed or global configuration, e.g. central master configuration
support for migration of configuration
