2. The instance <strong>cost</strong> per hour for the reserved instances for one <strong>and</strong> three years was calculated by taking <br />
into account a 60% <strong>and</strong> 80% usage rate. These rates are within the range of the utilization of the in-‐house <br />
infrastructure of the sample sites. <br />
3. The <strong>cost</strong> per instance hour was then transformed into <strong>cost</strong> per core hour by taking into account the <br />
number of cores an instance could refer to. <br />
The equivalence of the EC2 instances with the number of cores in present in the following Table (Table 9). <br />

Prices have been transformed from $ with exchange rate 1€ =$ 1.33270, http://www.alpha.gr/tools/eeurocur.htm <br />
(accessed on 16/1/2013). Amazon prices as on 16/1/2013. The prices refer to EU (Irel<strong>and</strong>). The prices of cluster <br />
