Which Are the Top Cited Publications and Authors in Cloud Computing?

The IEEE Transactions on Cloud Computing Journal is publishing a paper entitled “A Scientometric Analysis of Cloud Computing Literature” by Leonard Heilig and Stefan Voß (University of Hamburg) that presents an analysis of publication patterns, research impact and research productivity in the field of Cloud Computing. Two interesting results are the top cited publications and top cited authors in Cloud Computing.

 The results on the top publications in cloud computing show that the following paper is the top cited publication.


  • “Armbrust M., Fox A., Griffith R., Joseph A.D., Katz R., Konwinski A., Lee G., Patterson D., Rabkin A., Stoica I., Zaharia M. (2010) A view of cloud computing. Communications of the ACM 53(4):50-58.”  


I am proud to be a co-author of two publications listed number 7 and 17 respectively.


  • “Sotomayor B., Montero R.S., Llorente I.M., Foster I. (2009) Virtual infrastructure management in private and hybrid clouds. IEEE Internet Computing 13(5):14-22”, which describes the original OpenNebula design and architetcure, and 


  • “Rochwerger B., Breitgand D., Levy E., Galis A., Nagin K., Llorente I.M., Montero R., Wolfsthal Y., Elmroth E., Caceres J., Ben-Yehuda M., Emmerich W., Galan F. (2009) The Reservoir model and architecture for open federated cloud computing. IBM Journal of Research and Development 53(4):1-11”, which describes the cloud federation research and technology developed in the Reservoir Project. 


Regarding top authors, Rajkumar Buyya from University of Melbourne is the top cited author, while Ignacio M. Llorente and Rubén S. Montero are in the 26th position of the list. Only three European authors are part of the top cited authors list.

Bringing Private Cloud Computing to HPC and Science

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, and illustrated using real-life case studies from leading research and industry organizations how OpenNebula effectively addresses these challenges of cloud usage, scheduling, security, networking and storage. The keynote ended with a view of private cloud's future in HPC and science, and grid as the foundation of cloud federation.

OpenNebula: The European Management Platform to Build IaaS Clouds

Last Thursday, the blog of the European Commission Digital Agenda for Europe published an article entitled "OpenNebula: the only European open-source management platform to build IaaS clouds! A success story in exploitation of FP7 research results". It briefly shows how OpenNebula is playing an important role in driving and supporting the transition to cloud computing and thus accelerating the pace of innovation in Europe.

We are proud of being part of a project that is shaping the future of cloud computing!.

Key Challenges in Cloud Computing: Enabling the Future Internet of Services

"Key Challenges in Cloud Computing: Enabling the Future Internet of Services" is the title of our last article published in the August 2013 issue of the IEEE Internet Computing Magazine that describes how Cloud computing will play a major role in the future Internet of Services, enabling on-demand provisioning of applications, platforms, and computing infrastructures. The article describes the several technology challenges that must be addressed to turn this vision into reality. Specific issues relate to deploying future infrastructure-as-a-service clouds and include efficiently managing such clouds to deliver scalable and elastic service platforms on demand, developing cloud aggregation architectures and technologies that let cloud providers collaborate and interoperate, and improving cloud infrastructures' security, reliability, and energy efficiency.

Enjoy the article!

About the Openness of Eucalyptus, CloudStack, OpenStack and OpenNebula

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 cloud users really care about this? Users mainly want a solution that meets their functional needs, and are interested in open-source as a way to enhance flexibility, lower costs and avoid lock-in. However, as discussed in the post, most of these benefits are only available when an open-source software can be used in production environments without the addition of proprietary components. 

 It is worth reading!.

A Roadmap for Advanced Cloud Technologies under H2020

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 Future Cloud Computing evaluated the state-of-the-art and developed future research directions in cloud computing. This report is the main result of our last meeting in October 2012 to analyze the expected market development in which Europe can participate and which technological challenges will have to be faced in order to reach these scenarios.

So, enjoy the report. I think it is a must-read for people defining Cloud Computing strategies, developing innovative research lines, or exploring emerging market opportunities beyond today’s Clouds.

About the Complementarity of Eucalyptus, CloudStack, OpenStack and OpenNebula

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 CMP Quadrant, a tool aimed at aiding corporations to better understand the present and future landscape of the cloud market. 

I think it would be best for everyone from these open source projects to figure out how we can work together to better serve our users.

It is worth reading!.
