Themis: A Spot-Market Based Automatic Resource Scaling Framework
Résumé
Cloud computing brings new provisioning models that offer applications more flexibility and better control over their resource allocations. However these models suffer from the following problem: either they provide limited support for applications demanding quality of service, or they lead to a limited infrastructure utilization. In this paper we propose Themis, a novel resource management system for virtualized infrastructures based on a virtual economy. By limiting the coupling between the applications and the infrastructure through the use of a dynamic resource pricing mechanism, Themis can support diverse types of applications and performance goals while ensuring an efficient resource usage.
