Evaluation of resilience for Data Center systems

Data centers (DC) suffer from an increasing number of threats; these are exaggerated by the incredible growth of critical data volumes in addition to vulnerabilities in technologies used for distributed architectures. This paper demonstrates the need to define a new metric for ldquoresilience levelrdquo to complement other system metrics such as performance, availability, robustness and fault tolerance. In addition, ldquodata centerrdquo resiliencepsilas evaluation framework and its advantages are presented.
