The IEEE Transactions on Cloud Computing Journal is publishing a paper entitled “A Scientometric Analysis of Cloud Computing Literature” that presents an analysis of publication patterns, research impact and research productivity in the field of Cloud Computing. The following 2009 articles, which presented the original internal design and architecture of the Eucalyptus and OpenNebula cloud management platforms,

• “Nurmi D., Wolski R., Grzegorczyk C., Obertelli G., Soman S., Youseff L., Zagorodnov D. (2009) The eucalyptus open-source cloud-computing system. In: 9th IEEE/ACM International Symposium on Cluster Computing and the Grid, CCGRID 2009, pp. 124-131”, and
• “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.”

are in fourth and seventh position, respectively, of the top cited publications in cloud computing. This demonstrates the pioneering work done by these two well-known and widely-used open-source projects and the maturity of their open-source products.
