To determine this, two calculations can be used, the cost efficiency factor and the break-even point [6]. 1 Cost Efficiency Factor To calculate the cost efficiency factor for different systems, two values are required. The first one is the cost of the cloud systems. This cost, in the great majority of cloud providers, is expressed as cost per hour. The second value is the overhead factor. To determine this factor, it is necessary to execute the same workload in all the candidate systems and in the base system.

We want to compare the acquisition of a new cluster to a public cloud provider to verify which presents the best solution in our case. The first step is to verify if the application can be executed on both systems; because of the Unix execution model, it is compatible with the new cluster and with the cloud since both have a compatible operating system. The cloud provides adequate tools to create a cluster-like environment to execute p ­ arallel applications, and the delivery procedures are performed using standard network protocols, such as FTP (file transfer protocol).
