Abstract:
1. In a computer system, a method for transformation to a shared on demand infrastructure, the method comprising: identifying a sharable resource including at least one of a CPU resource type to analyze; calculating a number of servers in scope, Ns; collecting current resource usage data for systems in the scope, wherein the current resource data is provided by systems and performance management tools; identifying a Period P; counting a number of peaks, Np, in the Period, excluding adjacent spikes to each of the number of peaks; calculating an average of CPU usage, % Um, which is generally provided by the usage collection tools; defining an amplitude Am; defining a spare resources value for % Ks, in the range of 0.2-0.3; and applying transformation formulas to obtain a minimum size of a resource pool, a size of a target environment and a resource saving, wherein a transformation formula to calculate the minimum size of the resource pool, % MinPoolSize, is: wherein a transformation formula to calculate the size of the target environment, % Target Tr, is: wherein a transformation formula to calculate the resource saving, % Save Resource, is:
