TY - CHAP A1 - Günther, Oliver A1 - Tamm, Gerrit ED - Scheuermann, Peter T1 - A Framework for ASP-Marketplaces T2 - Cooperative Information Systems N2 - For organizations that plan to use online software applications via Internet one of the most important questions is, ”How do you choose the right ASP for the companies corporate needs?”. ASP marketplaces offer a plurality of pricing models and different levels of service. From whole system and whole service to single applications and methods, every digital product and service can be provided through an ASP marketplace. There is a need for ASP marketplaces, which gives the user a transparent insight into the ASP market. In this paper we define Application Service Providing in the context of Outsourcing. Then we analyze relevant software classes for ASP marketplaces. Finally we will set criteria to compare different levels of service of ASP marketplace. This paper gives an overview of key characteristics ASP marketplace provider must take into account by preparing the business process in order to successfully deliver application services.

At this point, it is still unclear why and when customers prefer the ASP model over more traditional approaches. To make ASP more attractive, more knowledge about possible pricing and product strategies is needed. In this paper we describe different business models for ASP marketplaces. We first compare the cost structures of the classical licensing model with the new server-based approach. Then we illustrate how price and product differentiation may improve overall market efficiency. In particular, we show that by selling different software versions for different prices, ASP marketplaces may obtain near-optimal revenues with products that are relatively inexpensive, disaggregated, and customizable. Consumers can thus choose between a wide variety of product lines to fit their differing budgets and requirements.

We present the results of an online experiment, where subjects were confronted with a variety of choices and decisions relating to web service markets and service composition. Our analysis shows that people expect the price of a composite web service to be lower than the sum of the prices of the elementary services, that is, users are not willing to pay for aggregation by a third party. To obtain a viable business model for composite web services, non-standard pricing mechanisms, such as auctions and negotiations, possibly supported by electronic agents, have to be taken into consideration. Usage-based pricing schemes, combined with an option to switch to a flat subscription, seem most appropriate to penetrate the developing market for web services.

Zahlreiche Softwareanbieter präsentieren sich am Markt als Application Service Provider (ASP), d.h. als Anbieter netzbasierter Anwendungsdienste. Hierbei kann das ASP-Modell den einzigen Vertriebskanal darstellen (reiner ASP) oder aber als Ergänzung neben das klassische Lizenzmodell treten. Während junge Firmen (wie z. B. Salesforce.com) ihr Glück als reiner ASP versuchen, wählen etablierte Anbieter im Regelfall die zuletzt genannte Option SAP mit seinem ASP-Produkt mySAP.com ist hierfür eines der bekannteren Beispiele.
