Right Scaling for Right Pricing: A Case Study on Total Cost of Ownership Measurement for Cloud Migration

Cloud computing promises traditional enterprises and independent software vendors a myriad of advantages over on-premise installations including cost, operational and organizational efficiencies. The decision to migrate software configured for on-premise delivery to the cloud requires careful technical consideration and planning. In this chapter, we discuss the impact of right-scaling on the cost modelling for migration decision making and price setting of software for commercial resale. An integrated process is presented for measuring total cost of ownership, taking in to account IaaS/PaaS resource consumption based on forecast SaaS usage levels. The process is illustrated with a real world case study

The role of mathematical modeling in VOC analysis using isoprene as a prototypic example

Isoprene is one of the most abundant endogenous volatile organic compounds (VOCs) contained in human breath and is considered to be a potentially useful biomarker for diagnostic and monitoring purposes. However, neither the exact biochemical origin of isoprene nor its physiological role are understood in sufficient depth, thus hindering the validation of breath isoprene tests in clinical routine. Exhaled isoprene concentrations are reported to change under different clinical and physiological conditions, especially in response to enhanced cardiovascular and respiratory activity. Investigating isoprene exhalation kinetics under dynamical exercise helps to gather the relevant experimental information for understanding the gas exchange phenomena associated with this important VOC. A first model for isoprene in exhaled breath has been developed by our research group. In the present paper, we aim at giving a concise overview of this model and describe its role in providing supportive evidence for a peripheral (extrahepatic) source of isoprene. In this sense, the results presented here may enable a new perspective on the biochemical processes governing isoprene formation in the human body.Comment: 17 page

Die Standardisierung des Marketing im internationalen E-Commerce

Die Standardisierung des Marketing ist seit den 1960er Jahren eine Schlüsselfrage bei der Internationalisierung von Unternehmen, zu der in den letzten Jahrzehnten zahlreiche Beiträge veröffentlicht worden sind. Allerdings fehlt es bisher an Studien, die dieser Frage im Rahmen des internationalen E-Commerce nachgehen. Die Autoren zeigen im vorliegenden Beitrag empirisch, dass die einzelnen Marketing-Instrumente und -Prozesse im internationalen B2C-E-Commerce in einem unterschiedlich hohen Maße standardisiert werden. Ferner wird mittels einer Kausalanalyse nachgewiesen, dass sich die Standardisierung des Marketing positiv auf den Unternehmenserfolg im internationalen E-Commerce auswirkt
