Estimating sustainability impact, total cost of ownership and dependability metrics on data center infrastructures

The advent of cloud computing has demanded more computational resources from data centers. Prominent issues are dependability, total cost of ownership and sustainability, which are significantly impacted by the redundant infrastructures needed to support cloud computing services. In this context, models are important to support data center designers to estimate previous issues before implementing the final infrastructure. This paper presents a set of formal models for estimating sustainability impact and dependability metrics in data center infrastructures with the support of an integrated environment, namely, ASTRO. Besides, we adopt reliability importance to identify the most critical components in system reliability in order to propose different data center power infrastructures.
