Sotomayor, BorjaLlorente, Ignacio M.Montero, Ruben S.Foster, Ian2023-06-202023-06-202009-091089-7801, ESSN: 1941-013110.1109/MIC.2009.119https://hdl.handle.net/20.500.14352/42718One of the many definitions of “cloud” is that of an infrastructure-as-a-service (IaaS) system, in which IT infrastructure is deployed in a provider’s data center as virtual machines. With IaaS clouds’ growing popularity, tools and technologies are emerging that can transform an organization’s existing infrastructure into a private or hybrid cloud. OpenNebula is an open source, virtual infrastructure manager that deploys virtualized services on both a local pool of resources and external IaaS clouds. Haizea, a resource lease manager, can act as a scheduling back end for OpenNebula, providing features not found in other cloud software or virtualization-based data center management software.engjournal articlehttp://ieeexplore.ieee.org/document/5233608/restricted access004Cloud computingInternet (Informática)RedesHardware3325 Tecnología de las Telecomunicaciones
