The OpenNebula Project has just announced the beta release of the fourth major version of its widely deployed OpenNebula cloud management platform, a fully open-source enterprise-grade solution to build and manage virtualized data centers and enterprise clouds. The project has come a long way since the first “technology preview” of OpenNebula five years ago. This latest release is the realization of a vision of simplicity, openness, code-correctness and a sysadmin-centric approach.
OpenNebula 4.0 brings valuable contributions from many of its thousands of deployments that include leading research and supercomputing centers like CERN, FermiLab, NASA, ESA and SARA; and industry leaders like Blackberry, ChinaMobile, Dell, Cisco, Akamai and Telefonica O2. As an enterprise-class product, OpenNebula offers an upgrade path so all existing users can easily migrate their production and experimental environments to the new version.
OpenNebula 4.0 includes new features in most of its subsystems:
- It features a completely redesigned Sunstone GUI, with a fresh and modern look and an updated workflow for most of the dialogs.
- A whole new set of operations for VMs like system and disk snapshoting, capacity re-sizing for vertical elasticity, programmable VM actions, NIC hotpugging, extended CLI and IPv6 support among others.
- Several improvements for administrators and new features to enhance the robustness and scalability of OpenNebula core like SysLog support, ACLs for clusters, new more efficient monitoring, better concurrency…
- Enhanced back-end in several areas like authentication with CRL support, virtualization with support for Xen 4 and new attributes for KVM and VMware, and storage with new Ceph drivers and improved iSCSI support
- Enhanced scheduler with cluster attributes for VM placement, affinity policies, and support for complex heuristics
OpenNebula 4.0 brings many more features, you have all the details in its release notes. OpenNebula is fully open-source software available for download under Apache 2.0 license.
