Cloudscape III – Driving Europe’s Cloud computing Strategy – took place on the 15 and 16 of March in Brussels offering the perfect opportunity for experts, developers and end-users in the cloud computing space to become part of the cloud standards process. The event, hosted by the EC-funded SIENA initiative, brought a 360° overview on the Cloud computing landscape, covering benefits for enterprise, research and government alongside challenges spanning scalability, data movement, ownership and privacy, security and legal issues, openness and interoperability.

The SIENA initiative presented its document SIENA European Roadmap on Grid and Cloud Standards for e-Science and Beyond. This document addresses requirements, technologies, and interoperability and standards for e-infrastructure to support existing, ongoing, and future research in the European Research Area. The document includes use cases and position papers collected for the Cloudscape III  event. Many of these use cases refer to OpenNebula as core component in their architecture and as a reference open cloud stack to enable interoperable enterprise class cloud computing platforms. Our presentation in this strategic event described the position of OpenNebula on interoperability and standards for cloud computing.

Today, the OpenNebula project announces the general availability of the final release of OpenNebula 2.2.0. This is a stable version and it is targeted at production deployments. Clouds running any OpenNebula 2.0.x versions are recommended to upgrade to this release.

Among the new features, OpenNebula 2.2.0 includes Sunstone, a web application to control your cloud with lots of eye candy. OpenNebula 2.2.0 also brings important new features in the fault tolerance and scalability areas. OpenNebula 2.2 is the seventh major release of the project and with it, it continues to fulfill the promise of building a state-of-the-art open source toolkit that also addresses the scalability, flexibility and security requirements of large-scale production systems.

As usual OpenNebula releases are named after a Nebula. The Cat’s Eye Nebula (NGC 6543, Caldwell 6) is a planetary nebula in the constellation of Draco.


The OpenNebula project would like to thank the community for their effort and valuable contributions that have made possible this release; the European Commission for founding part of the developments of this release through the StratusLab and BonFIRE research grants; and our private sponsor, C12G Labs, for supporting the community and software contributions.

The March edition of the Internet of Services newsletter features OpenNebula as spinoff of RESERVOIR. This newsletter reports about the activities of the Software & Service Architectures and Infrastructures Unit in the Information Society Directorate-General of the European Commission. The article highlights the innovation and interoperability of OpenNebula and its high number of downloads and adoption in production environments. OpenNebula is being used as reference open stack for cloud computing in many large research and infrastructure projects.

In the last issue of IEEE Internet Computing, Dejan Milojicic, editor in chief of Computing Now, discusses cloud computing and OpenNebula with Ignacio M. Llorente and Rubén S. Montero, leads of the open source OpenNebula project. The video is available online in the Trend Wars section at the Computing Now site and the transcript has been published in the March/April issue of IEEE Internet Computing.

As you probably noticed, last week we migrated the OpenNebula community services (web pages, development repos…) to a new infrastructure to accommodate the quickly increasing number of visits and downloads. As a result the RC announcement did not hit the list, the software was available, though.

OpenNebula 2.2 RC1 is the last development release of the OpenNebula toolkit. Although OpenNebula RC1 is targeted at testers that would like to check the exciting new features of OpenNebula 2.2, it is considered stable enough for daily operations. OpenNebula 2.2 RC1 adds general stability, and performance improvements as well as the features from previous OpenNebula 2.2 Betas. OpenNebula 2.2 RC1 is backward compatible with the 2.x series in terms of the database schema, interfaces and API’s.

We really appreciate the work of the community testing the previous release and giving feedback about issues and bugs. Thanks!

As an open-source community partially funded with public funding, it is very important for us to keep an updated list of organizations and projects using OpenNebula. Doing so puts us in a better position to get grants and keep OpenNebula well funded through a combination of public and private funding.

If your organization or project is not listed in our Users and Projects page, and you would be willing to be listed, please fill out this really quick form or contact our community manager. Details of your OpenNebula deployment are welcome, but not strictly necessary, as we know it is often not possible to reveal this information publicly. Just allowing us to list the name of your organization on the Users and Projects page would be enough.

The RESERVOIR project is organizing an OpenNebula training session in Paris on March 22, similar to the one held in Brussels last January. The training will be given by CETIC and the RESERVOIR project and will take place in La Cantine.

RESERVOIR is an IBM-led joint research initiative of 13 European partners to develop technologies that help automate the fluctuating demand for IT resources in a cloud computing environment. To pave the way to adoption of cloud technology by businesses, the RESERVOIR project has integrated a set of virtualization and cloud management tools. The participants will learn about the global architecture of the RESERVOIR Framework, with a particular attention given to OpenNebula. The training will cover the management aspects: installation, configuration and administration. The participants will also learn about the use of OpenNebula, including private, hybrid and public cloud topologies. The course includes hands-on exercises to be performed using attendee’s laptops.

This event is free of charge, but you must register by sending an e-mail to as attendance is restricted to 20 persons.

Thanks to the hybrid cloud computing functionality offered by OpenNebula, external clouds are seen in an OpenNebula system as other local resources. In this way, Sunstone allows the management of all the public clouds that are used in the hybrid configuration of any given enterprise.

This setup is shown in the screenshot, where a private cloud is shown with associated external resources (in this case, three Amazon availability zones), where the compute power can be outsourced during peak demands.

The TCLOUDS project organized a hands-on tutorial about OpenNebula in a meeting in Lisbon, on January 19, 2011. TCLOUDS is an integrated research project financed by European Commission’s FP7 on trustworthy cloud infrastructures and the partners from the University of Lisbon’s Navigators team presented a tutorial to introduce OpenNebula through a user perspective.

OpenNebula components were presented, along with their interactions and interfaces. The participants were able to deploy, use and remove virtual machines in a virtual network. The tutorial used an OpenNebula infrastructure installed in the premises of the University of Lisbon. More advanced features were addressed in the same meeting, in two other technical presentations about OpenNebula.
