Risks and rewards of moving applications to the cloud – a white paper

We have recently come across an interesting discussion group called “Cloudusecases.org”. It has published two white papers titled “Cloud Computing Use Cases White Paper” and “Moving to the Cloud – Risks and rewards of moving applications to the cloud“. Both papers are very interesting and informative. Especially the second one suggests the following very straight […]

Comparing Cloud Computing Prices

During our research we have recently come across an interesting blog with the title “The Case for a Cloud Computing Price War”, where the author  Daniel Berninger argues that Amazon has kept prices for its EC2 offering stable over years, without handing over price performance improvements to its customers. The article further on argues that […]

Costs for running scientific applications on EC2 significantly higher in comparison to in-house infrastructure

We have recently written a scientific article on “Towards a Model for Cloud Computing Cost Estimation with Reserved Instances”.  Cloud computing has been touted as a lower-cost alternative to in-house IT infrastructure recently. However, case studies and anecdotal evidence suggest that it is not always cheaper to use cloud computing resources in lieu of in-house […]

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 […]
