Fig. 1From: Scalability resilience framework using application-level fault injection for cloud-based software servicesThe calculation of the scalability performance metrics: a) the volume scalability metric is ηI, which is the ratio between the areas A and A*; b) the quality scalability metric is ηt, which is the ratio between the areas B* and. The red lines indicate the ideal scaling behaviour and the blue curves show the actual scaling behaviour [2; page 5]Back to article page
