Service-Oriented Architecture: An Integration Blueprint

OSGi

OSGi is a hardware-independent, dynamic software platform that simplifies the process of modularizing distributed applications and their services, and managing them throughout their entire life cycle (Wütherich et al. 2008). The OSGi platform requires a Java Virtual Machine (JVM) and provides a framework on the basis of the JVM. The OSGi alliance (Open Service Gateway initiative) is an industry consortium consisting of a number of manufacturers from different sectors, which originally developed the platform for use in embedded systems. The most important features of OSGi are as follows:

• OSGi architecture: OSGi defines the following layers as its base architecture:
  • Execution environment
  • Module
  • Life cycle
  • Services
  • Security
  • Applications
• Component model ...
