A suggested taxonomy for Governmental Clouds

Cloud Computing has undoubtedly been the most disruptive IT paradigm of the last two decades, spanning a wide area of technologies and implementations. Its emergence is already transforming the public sector with relevant e-Government use cases. The adoption of various cloud-related initiatives as part of national strategies is driving the need to use a common framework to better describe, analyse and compare those implementations, known as "Governmental Clouds". In addition, for any interoperability to be effective in the long run, a standard framework and common language to describe the relevant ontologies should exist. This paper aims to introduce and discuss a taxonomy of three different models based on the existing and emerging Cloud Computing governmental best practices and available use cases, addressing the lack of relevant concrete definitions.
