OpenNebula has just released a Deltacloud adaptor to build Hybrid Clouds. A Hybrid Cloud is an extension of a Private Cloud to combine local resources with resources from one or several remote Cloud providers. The remote provider could be a commercial Cloud service or a partner private infrastructure running a different OpenNebula instance. Hybrid Cloud computing functionality enables the building of cloudbursting and cloud federation scenarios. OpenNebula provides support for building Hybrid Clouds with Amazon EC2 and ElasticHost, and now with this new adaptor OpenNebula leverages RedHat Deltacloud to access any major public cloud, such as GoGrid, Rackspace, Terremark or RimuHosting and Private clouds running OpenNebula or RHEV-M. A single OpenNebula management instance can be used to combine local infrastructure with multiple remote clouds, so building a highly... (more)

OpenNebula Cloud Scaling to 16,000 VMS

Ulrich Schwickerath, from the CERN IT-PES/PS Group, presented at ISC Cloud 2010 the last benchmarking results of CERN's OpenNebula cloud for batch processing. The batch computing farm makes a critical part of the CERN data centre. By making use of the new IaaS cloud, both the virtual machine provisioning system and the batch application itself have been tested extensively at large scale. The results show OpenNebula managing 16,000 virtual machines to support a virtualized computing cluster that executes 400,000 jobs. CERN published in June a description of its Cloud deployment....

Why OpenNebula? Because It Simply Works!

“Because it simply works” is the most frequent answer to the question “Why would you recommend OpenNebula to a colleague?” that OpenNebula makes to its users in a short survey that tells them how they are doing. Other frequent answers are “Because it is easy to install, maintain and update” or  “Because it is easy to customize”. “Rich functionality and stability” and “support for VMware” are also frequently mentioned by the survey respondents.   The main reasons for using OpenNebula have changed little since they wrote a first post with the Top 10 a couple of years ago. Thanks ... (more)

OpenNebula 4.0 Beta Enterprise Cloud Management Platform Is Out

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 includ... (more)

Simplicity Is What Differentiates the New OpenNebula 4.6

Code-named “Carina”, the twenty-first release of OpenNebula is available today with a new innovative provisioning model based on virtual Data Centers that offers a simple but comprehensive framework for resource allocation to different groups of users in federated data centers and hybrid cloud deployments. Carina brings the ability to easily federate multiple OpenNebula clouds for high availability, scalability, isolation or multiple-site support, and the seamless sharing of golden images across these zones through a new revamped AppMarket. Users can also browse and provision ser... (more)
