OpenNebula provides a subset of the functionality offered by proprietary solutions, like VMware’s vCloud Director. This subset is enough for most infrastructure owners, and in exchange OpenNebula let’s you manage a cloud infrastructure without an army of system administrators. Because it is completely hypervisor agnostic, fully supports VMware, and is easy to install, maintain and use within existing VMware environments, OpenNebula is widely used as an open alternative to VMware vCloud at significantly lower costs. Some of our users also see OpenNebula as a migration tool that allows them to perform a smooth transition from VMware to more open hypervisor alternatives like KVM. In other words OpenNebula leverages existing VMware infrastructure, protecting IT investments, and at the same time avoids future vendor lock-in, strengthening the negotiating position of the enterprise.
