RT Conference Proceedings T1 Towards elastic virtual machine placement in overbooked openstack clouds under uncertainty A1 López, Fabio A1 Barán Cegla, Benjamín A1 Pereira, Carolina A1 Velázquez, Marcelo A1 González, Osvaldo Miguel A2 Universidad Nacional del Este - Facultad Politécnica AB Cloud computing datacenters currently provide millions of virtual machines in highly dynamic Infrastructure as a Service (IaaS) markets. As a first step on implementing algorithms previously proposed by the authors for Virtual Machine Placement (VMP) in a real world IaaS middleware, this work presents an experimental comparison of these algorithms against current algorithms considered for solving VMP problems in OpenStack. Several experiments considering scenario based simulations for uncertainty modelling demonstrate that the proposed algorithms present promising results for its implementation towards real-world operations. Next research steps are also summarized.
