State of the Art (Year 1)

This report complements ASCETiC Requirements Specification (Year 1) and documents the state of the art in the technology areas of the project plus the progress to be done by ASCETiC. Its purpose is to clarify the baseline, progress and state of the art that ASCETiC will address.
The document is structured in three different sections related to the Cloud service life cycle development, deployment and operation and a fourth section on economics of green Clouds.
ASCETiC will result in an implementation of an open-source Cloud stack providing energy efficiency at software, platform, and infrastructure layers. Incremental versions of the ASCETiC outcomes with respect to energy efficiency will be provided, approaching the problem in three levels: static, intra-layer and inter-layer adaptation.
