The Open Services Gateway Initiative (OSGi) Alliance is working to realize the vision of a "universal middleware" that will address issues such as application packaging, versioning, deployment, publication, and discovery.
In this article we'll examine the need for the kind of container model provided by the OSGi, outline the capabilities it would provide, and discuss its relationship to complementary technologies such as SOA, SCA, and Spring. Enterprise software is often composed of large amounts of complex interdependent logic that makes it hard to adapt readily to changes in requirements from the business. You can enable this kind of agility by following a Service Oriented Architecture (SOA) pattern that refactors a system into application modules grouped by business functions that expose their public functionality as services (interfaces).

It's worth mentioning that Spring Dynamic Modules for OSGi Service Platforms (or the Spring OSGi integration in short), had its 1.0 final release, after 3 milestones and 3 release candidates, on January 25th, 2008.
The official announcement can be found at: http://www.springsource.com/web/guest/2008/spring-dm-intro

Those interested in a commercial distributed runtime, built from the ground up using OSGi R4 and SCA, may be interested in the Infiniflow Service Fabric - see www.paremus.com, or its open source relation newton.codecauldron.org.
In addition to having leveraged these important industry developments for the last 18 months, Infiniflow, described by analysts as a Cloud OS or virtual application server, augments these with industry unique self-managing, self-scaling behaviors, and with transparent runtime support for Spring Dynamic Modules.
