Abstract—Cloud infrastructures are a very common way to
provide IT services nowadays. Any cloud provider is interested
in designing appropriate systems and optimizing usage rates.
Within an educational area elastic IT services can support
administration and also students’ courses. Therefore this paper
scopes onto the calculation needs of an educational cloud
environment. The primary intention is to get a generally valid
counting algorithm which fits for different universities and
colleges, no matter if they have apprenticeship training or not.
The presented credit system does not focus on maximum income
but aims to achieve the optimum output rate and operating
grade of the available hardware resources. The paper explains
furthermore the basic facts and possible presumptions which are
necessary for designing a credit system that shall be easy and
universally applicable. Finally a formula is presented, which
allows educational institutes to forecast their demand of virtual
resources and a key to partitioning.
Index Terms—Cloud computing, credit system, Linux,
resources, right sizing, virtualization.
