The document introduces Kemp's total cost of ownership (TCO) calculator, which allows users to compare the licensing costs of Kemp's metered licensing model against perpetual and competitive licensing models. It provides three common application usage scenarios - peak usage, steady growth, and on-demand - to model licensing costs over time. The TCO calculator aims to give users insight into their estimated licensing costs for their application infrastructure based on factors like required application delivery controller (ADC) capacity and quantity, traffic growth rates, and usage peaks.
