This post has been prepared as contribution to the Boston Open Research Cloud Workshop that MIT is hosting on May 11-12, 2017. The aim of the workshop is to discuss the issues, reach consensus on how to move forward, and begin actively working towards the establishment of a federated s...
Nine years ago, in February 2008, OpenNebula announced the first open-source management software for deploying private and hybrid clouds, and released one of the most transformative platforms for innovation in the cloud. OpenNebula was the first of many open-source software components ...
It was a couple of years ago in march 2014 when we wrote about the small user base and penetration in the market of OpenStack, mostly compared with the investment made by vendors and VCs. At that time we estimated that the investment in OpenStack was approximately $300 million per year...
This case study assumes you want to build a private cloud on top of an existing virtualized datacenter composed of multiple hosts running vSphere and managed by one or several instances of vCenter. It is understood that you do not want to abandon your investment in VMware by retooling ...

In our last post "OpenNebula vs. OpenStack: User Needs vs. Vendor Driven" we stated that"OpenStack penetration in the market is relatively small compared with the investment made by vendors and VCs". We have received several emails from people asking for the numbers that support this s...
How do you compare OpenNebula with OpenStack?... This is indeed a complex question. There is no single answer because open-source projects and technologies present several dimensions. But we are far from afraid to answer it: the short, tl;dr version would be that they represent two di...
HPC-optimized clouds provide access to flexible and elastic scientific and technical computing to solve complex problems and drive innovation. You can find bellow the slides of my keynote at EGI-TF 2013 where I described the most demanded features for building HPC and science clouds, a...

The OpenNebula Project has just announced the support for the creation and operation of OpenNebula User Groups. An OpenNebula User Group is a gathering of our users in a local area to share best practices, discuss technical questions, network, and learn from each other. These are impor...
We have just published a post at the OpenNebula blog with our view about the different measures that should be considered to evaluate the openness of the main open-source Cloud Management Platforms (CMPs). Which is the most important measure of openness in cloud computing? Do the clou...
This is the title of the last report prepared by the EC Cloud Expert Group that proposes a concrete roadmap to help Europe overcome existing technological challenges and reach a key position in the global Cloud market. The previous reports on Advances in Clouds - Research in Futur...
We have just published at the OpenNebula blog our experience about the different types of cloud models, from datacenter virtualization to infrastructure provision, and about how the main open-source Cloud Management Platforms (CMPs) are targeting their needs. The post introduces the CM...
"IaaS Cloud Architecture: From Virtualized Datacenters to Federated Cloud Infrastructures"  is the title of our last article published in the December 2012 issue of the IEEE Computer Magazine that presents an architecture reference model for IaaS clouds. The ar...
Neelie Kroes, European Commissioner for Digital Agenda, presented on Friday at the Open Source Conference 2012 the three ways the European Union (EU) is supporting Open ICT systems, namely open-source, open-procurement, and open-data. Mrs. Kroes outlined the huge benefits of open-sourc...
Here is the recording of the OpenNebula session at GigaOM Structure Europe. The interview covers the OpenNebula's focus on user needs and its recipe for success described in the post David Versus Goliath in Open-source Cloud Computing: The OpenNebula Recipe for Success.
Now that OpenNebula has been listed by GigaOM on the list of main reasons why Europe really matters to cloud computing, I am receiving several emails asking about how OpenNebula is able, what’s its "secret recipe", to compete with other open-source projects, like OpenStack, CloudStack ...
During the last two years I have been reporting about the different consultation events undertaken during the development of the cloud computing strategy. Now, finally, the European Union has just announced a strategy to boost the use of cloud computing among its members in the private...
What Role Does Open-source Play in Cloud Computing Innovation? is a guest post that I have written on GigaOM to show how open-source is playing an important role in driving and supporting the transition to cloud computing. According to our experience, the availability of open-source cl...
I have decided to write this post after receiving several emails from different people asking me about the reasons for the slower adoption of cloud computing in Europe. In comparison to the US, it is clear that EU is some years behind in size and maturity of cloud infrastructure provis...
Yesterday we participated in the second edition of the cloud computing workshop within the Digital Agenda Assembly 2012 aimed at defining the European Cloud Computing Strategy. Last year, the aim of the workshop was to identify the main elements of a European cloud strategy and the pos...
