OpenNebula 4.2 Released

New version of OpenNebula with multi-tier cloud application orchestration and tighter integration with VMware and Xen, and final speaker line-up for OpenNebula Conference 2013 with industry and research leaders.

The OpenNebula Project is excited to announce the first update of the fourth series of its widely deployed OpenNebula cloud management platform, a fully open-source solution for data center management and enterprise cloud computing. With a sysadmin-centric approach, OpenNebula is the open operating system of choice in the converged data centre, combining a powerful virtualization manager that supports traditional IT features such as fault tolerance and failover, with the dynamic provisioning, elasticity and multi-tenancy of the enterprise cloud.

OpenNebula 4.2 gives users and administrators an easy way to create, publish, share, and manage multi-tier cloud applications and define auto-scaling policies based on service level metrics and time schedule. The new service flow functionality converts an infrastructure cloud into a powerful environment for the execution of elastic business applications. OpenNebula 4.2 also includes improved VMware drivers, enhanced support for Xen4, a new simple provisioning tab for Sunstone, and other minor enhancements like datastore monitoring and more hooks.

“The new features make OpenNebula the most advanced open replacement for vCloud,” said Ruben S. Montero, Chief Architect of OpenNebula. “The new update offers a unique, application-centric approach to help organizations increase business agility,” said Ignacio M. Llorente, Director of OpenNebula.

OpenNebula 4.2 will be shown at OpenNebula Conference 2013, from 24 to 26 of September in Berlin. This first ever OpenNebula Conference will serve as a meeting point of cloud users, developers, administrators, builders, integrators and researchers, featuring talks with experiences and use cases from organizations like Produban - Bank Santander Group, China Mobile, FermiLab, Deutsche Post E-Post, European Space Agency, CentOS Project, Akamai, and BBC. The Conference agenda ( also includes a hands-on tutorial, lightning talks, as well as hacking and open space sessions that will provide an opportunity to present and discuss burning ideas, and meet face to face to discuss development.
