OpenStack-based Clouds as Holons: A Functional Perspective

The generalization of distributed systems-of-systems lead to increasing management and operation complexity. A sound approach to deal with this complexity is to leverage overlay networks and the higher level of abstraction they allow for distributed operations. In particular, the virtualization of underlying network resources allows providing a range of reusable network services and compose them with existing systems. Recently, the notion of holons as compositional systems entities was proposed as a general framework for the programming and deployment of complex systems of systems. We investigate if this abstract model can be applied to the complex process of real-time composition of OpenStack-based IaaS clouds. In this context, we also address issues related to the energy-performance tradeoff using techniques similar to those involving dynamic service consolidations. Our solution aims at simplifying the life of infrastructure and service providers, allowing them to face the dynamicity of new demands in Future Internet.
