Abstract: Cloud computing re-defined what, in Information and Communication Technologies, can be delivered "as a service". The new types of services and the associated monetization models that were implemented increase the potential of some Service-Oriented Architecture concepts, namely dynamicity discovery and use. Presented with this scenario, we envision is a dynamic cloud-enabled service ecosystem in which different players positioned in different areas of the ecosystem cooperate to deliver scalable high-value services to the end user. The different providers should be able to discover, request, use and discard services during runtime based on some internal management logic.
In order to help specify the ecosystem we envision, a reference model was defined and dynamicity aspects were identified. Furthermore, requirements were derived and classified based on the devised reference model and aspects. A State-of-the-Art of the related technologies, as well as a classification regarding the same criteria, was analyzed, enabling us to present a possible solution for implementing our vision, and to identify challenges that still need to be addressed. Finally we anticipate the business-related evolution towards the dynamic cloud.
Applicability: Technical and business strategists, innovation coordinators and R&D project leaders and researchers.
