Surveying clouds in a global environment

Abstract

This paper reports on the results of the survey regarding the Research and Education (R&E) clouds in a number of world regions covered by the CHAIN-REDS project, including the sub-Saharan Africa. The survey includes the technical aspects of R&E clouds, as well as issues related to interoperation, interoperability, compatibility, orchestration and federation. Results obtained show a high interest in standards, thus pointing to the fact that the cloud solutions offered by CHAIN-REDS, which include a global cloud federation test-bed and the use of OCCI and CDMI standards, provide a building block for global cloud federated environment.
