From the analysis in Graph 13, the cost per core/hour compared to the Amazon adjusted prices for Standard
M/L/XL instances – Linux is as follows:
The cost per core hour of e-­‐FISCAL median becomes less expensive when the e-­‐Infrastructure operates:
• At 30% utilisation rate or more compared to on demand instances.
• At 40% utilisation rate or more compared to 1-­‐year reserved instances utilised at 60%.
• At approx. 50% utilisation rate or more compared to 1-­‐year reserved instances utilised at 80%.
• At approx. 65% utilisation rate or more compared to 3-­‐year reserved instances utilised at 60%.
• At approx. 75% utilisation rate or more compared to 3-­‐year reserved instances utilised at 80%.
The cost per core hour of e-­‐FISCAL average becomes less expensive when the e-­‐Infrastructure operates:
• At approx. 60% rate or more compared to on demand instances.
• At 80% utilisation rate or more compared to 1-­‐year reserved instances utilized at 60%.
• At approx. 95% utilisation rate or more compared to 1-­‐year reserved instances utilized at 80%.
• The cost per core hour of e-­‐FISCAL average is more than the performance adjusted price for 3-­‐year
reserved instances in 60% and 80% usage rates.

Graph 14: Identification of the Indifference point between e-FISCAL cost and Amazon adjusted for
performance prices (Cluster Compute Quadruple XL instances – Linux)
From the analysis in Graph 14, the cost per core/hour compared to the Amazon adjusted prices for Cluster
Compute Quadruple XL instances – Linux is as follows:
The cost per core hour of e-­‐FISCAL median becomes less expensive when the e-­‐Infrastructure operates:
