OpenNebula features unique functionality for virtualization of the datacenter. Among them, it is worth highlighting its support to build cloud bursting architectures where private cloud resources can be easily supplemented with resources from a remote public cloud to meet fluctuating demands. The reason behind this uniqueness is the transparency to use and maintain the cloud bursting functionality for both end users and cloud administrators.
The latest version of OpenNebula, Carina, offers a simple but comprehensive framework that enables resource allocation to different groups of users in federated data centers and hybrid cloud deployments. OpenNebula offers a single management point for both local private and remote public cloud resources, with an end user self-service portal (Cloud View) that enables the consumption of hybrid virtual machine templates. These hybrid templates are intended to define identical virtual machines -in terms of provided service- whether they get deployed in the local infrastructure using local resources, or if the scheduler decides to deploy them remotely in a public cloud provider.
