Cloud computing is an attractive computing model since it allows for resources to be provisioned according on a demand basis, i.e., cloud users can rent resources as they become necessary. With IaaS, IT services can be delivered as a subscription service, eliminating up-front costs and driving down ongoing support costs. As with managed hosting, IaaS providers keep costs low by pooling resources and giving customers access to a shared facility. But a major difference is that IaaS resources are elastic and available on a self-service, on-demand basis. The convergence of those trends, with other advances of the last several years, has made it possible to take infrastructure outsourcing to a new level. Building on the foundation of managed service such as Infrastructure-as-a-Service (IaaS) has emerged as an easily deployed service that enables companies to flexibly and cost-effectively anticipate and evolve with their customers’ rapidly changing business requirements. This paper analyses opens source solutions like XCP, Nimbus, OpenNebula, Eucalyptus, Enomaly, OpenStack for infrastructure in Cloud which uses KVM and Xen hypervisor.
