Leveraging the cloud for Green IT

The third paper we want to look at, A. Spellmann et al., “Leveraging the Cloud for Green IT: Predicting the Energy, Cost and Performance of Cloud Computing” (1),  deals with the green aspects of cloud computing. This might not look like a paper contributing very much to cloud computing economics at first fight. This paper [...]

To cloud or not to cloud as a function of data center utilization

The economics of cloud computing is a topic that is far less trivial than it looks at first sight. Despite cloud computing being one of the big buzzwords in IT these days, literature on cloud computing economics is very rare. We have screened a significant part of the research on cloud computing and selected  three [...]
