• Identification of the layers of the application,
• Definition of the services,
• Granularity (what are the boundaries of a service, ...),
• Dependency with libraries,
• Testing and debugginf debugging strategies,
• Deployment procedure,
• Infrastructure

Some of the points mentioned are particular to SOA world like granularity and definition of service boundaries but others are mostly found in all IT projects. This is really important to keep them in your head because they will impact the project life cycle, quality of the deliverable, efficiency of the team and project duration/cost.

In this second part of the tutorial we will investigate some of the points mentioned and applied them to a real application. The application will be designed around different components (= bundles in the OSGI jargon) and deployed into ServiceMix Kernel. ServiceMix Kernel or SMXKNL is an OSGI platform created top of Apache Felix OSGI server, integrating Spring Dynamic Modules to facilitate the build of Spring application and PAX components who provide tools managing deployment of component and web support.

For more information about the projects mentioned, I recommend that you have a look on their respective web site.
