====== OpenNebula 4.4 Released ======

//Release of OpenNebula Retina with a simple but feature-rich, customizable and open solution to manage enterprise private clouds and virtualized data centers
//

The OpenNebula Project is excited to announce the nineteenth stable release 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 4.4 Retina includes support for multiple system datastores, which enables the definition of scheduling policies for storage load balancing. The monitoring subsystem has switched from a pulling mechanism to a massively scalable pushing model, being now able to monitor hundreds of thousands of VMs in a few minutes. An important effort has been also made in enhancing the support for cloud bursting to Amazon, enabling a transparent offload of computing power whenever the local infrastructure cannot cope with the demand. Moreover, the Amazon EC2 and EBS interfaces implemented by OpenNebula have been revisited and extended to support new functionality.

//"OpenNebula’s roadmap is completely driven by users needs with features that meet real demands, not features that result from an agreement between IT vendors planning to create their own proprietary solution”//, said Ruben S. Montero, Chief Architect of OpenNebula. //"An active and engaged community, along with our focus on solving real user needs in innovative ways and the involvement of the users in a really vendor-agnostic project, constitute the OpenNebula’s recipe to success"//, said Ignacio M. Llorente, Director of OpenNebula.

With tens of thousands of deployments around the globe, OpenNebula is parked in some of the biggest organizations including research leaders like FermiLab, European Space Agency and SurfSARA, and industry leaders like Produban – Bank Santander, Akamai, CentOS, BBC, Blackberry and China Mobile. The first OpenNebula Conference, held in Berlin in October 2013, served as a meeting point of cloud users, developers, administrators and builders, and featured talks with experiences and use cases from these organizations.
