CACTOS

In order to address key research challenges:

1. How to model heterogeneous workloads, infrastructure-architecture models and topologies as well as facility management information and energy supplier information within a coherent information model.
2. Realization of new infrastructure management methods that integrate different aspects into a unified multi-dimensional optimization model. -Development of a simulation framework for conducting costs and risk analysis in order to validate the intelligent Context-Aware Cloud Topology Optimization strategies for robustness on a large scale beyond the limits of prototypical installations and deployments

CACTOS copes with the challenge of optimizing the mapping of services to a variety of different resources, which are both hardware and software related (e.g. high bandwidth demands), and require topology aware mapping. This mapping needs to consider placement of the services across geographically distributed centers and demands new intelligent and cross-domain integration of actual and historical usage data.
