Today, service providers need to develop competitive applications for a quick time-to-market to attract and retain end users. To facilitate the task of developers, we introduce a reference Service Creation Environment based on service component and self-management mechanisms. This environment uses a fairly high integration level using meta-modeling techniques and exchange formats: Meta-Object Facility (MOF), Extensible Markup Language (XML), OVF ++ (Open Virtualization Format). Our approach allows developers to design the basic service components based on Quality of Service (QoS), to build the service by composition, and to manage a mobile session by ubiquitous services and the Virtual Service Community.
