Payment models for information services
Dušek, Marek ; Gála, Libor (advisor) ; Šamánek, Robert (referee)
Due to the increasing economical significance of information services the thesis attempts to map possible payments models (revenue streams) and compile relevant selection criteria. First part is therefore dedicated to clarify the very basic terms, such as general and information service, followed by a description of web services as an implementation of their particular subset. This somewhat more technically and technologically oriented chapter covers standards as XML-RPC, SOAP, REST, WSDL and UDDI. Next part's goal is to explore the most important non-functional aspects of information services operation, including QoS and security, guaranteed by outlined SLA contracts. To meet these requirements, additional infrastructure components are needed, such as an identity management, monitoring, metering and accounting. Different pricing strategies, involving differentiation and bundling, are followed by an analysis of possible payment models themselves, divided to both revenue (transactional, subscription, register, licensing, one-time) and non-revenue (provider-supported, advertisement, freemium) based. Covered models are briefly described and their advantages and disadvantages proposed, as well as their infrastructure prerequisites and key metrics. The final chapter compiles relevant selection criteria and uses them to compare the chosen models, so that providers are given a guide when dealing with a service pricing.
