Virtual Infrastructure Management in Private and Hybrid Clouds

One 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.
