The need to comprehend clouds: Why we still can’t use clouds properly

Abstract

Clouds have become the modern concept of utility computing – not only over the web, but in general. As such, they are the seeming solution for all kind of computing and storage problems, ranging from simple database servers to high performance computing. However, clouds have specific characteristics and hence design specifics which impact on the capability scope of the use cases. This paper shows which subset of computing cases actually meet the cloud paradigm and what is needed to move further applications into the cloud.
