Pricing Web Services

This paper focuses on the challenges associated with composing and pricing web services. 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.Peer Reviewe

As the Online World Turns

The relationship between online vendors and content providers was a major issue at the 1997 Online World conference. Other important topics included pricing of online services and Web sites of online providers

Pricing Web Advertisement: Display Ads V.S. Contextual Ads

Most web sites provide display advertising and contextual advertising services simultaneously, which are the main ad formats in Internet. With multimedia format, the pricing of display ads is generally based on the occurrence of ad impressions. However, targeting their customers more accurately, contextual ads are performance based advertisements and are charged only if one visitor clicks a client’s appointed ad. In this paper, we develop an economic model to examine the pricing strategy, profitability, and social efficiency of these two heterogeneous web advertising channels, with respect to different market structures

Impacts of e-Commerce and Enhanced Information Endowments on Financial Services: A Quantitative Analysis of Transparency, Differential Pricing, and Disintermediation

Some implications of e-Commerce financial services firms are becoming clear. The web drives transparency, and increases the information endowment of all market participants. It is harder to manipulate customers\u27 behavior, or to overcharge them. Transparency drives differential pricing. Not all customers can or should be charged the same prices. Transparency reduces the viability of cross-subsidies between customers can or between products. The differential pricing enabled by the web transforms distribution channels, and enables direct distribution and alternative forms of distribution. Some intermediateraries may be bypassed altogether, while others may rapidly lose their best, most profitable, and previously most loyal customers

IMPLEMENTASI PENGUKURAN DAN PENGHITUNGAN BIAYA BERDASARKAN QoS PADA BROKER WEB SERVICE (ON THE IMPLEMENTATION CALCULATING OF QoS BASED MEASUREMENT AND ACCOUNTING ON A WEB SERVICE BROKER)

ABSTRAKSI: Teknologi Web Service telah menjadi suatu teknologi populer yang sangat penting dalam pengembangan dan integrasi web application. Berdasarkan open standar seperti SOAP, WSDL, UDDI, dan BPEL4WS, web service memungkinkan applikasi berbasiskan web untuk berkomunikasi dengan menggunakan message XML yang terstandarisasi dan membentuk suatu sistem terdistribusi. Sementara teknologi web service membentuk sebuah model komunikasi baru, yaitu infrastruktur dan sistem aplikasi disediakan oleh service provider dan disajikan kepada service consumer melalui sebuah web service, sumber daya-sumber daya seperti network bandwidth, storage throughtput perlu untuk dialokasikan sedemikian rupa sehingga service provider dan service consumer bisa mendapatkan keuntungan yang maksimal dengan penggunaan web service. Karena itu tujuan dari “pricing” pada web service adalah untuk mengoptimalkan keuntungan dari operasi bisnis yang menggunakan web service dengan menyesuaikan perhitungan dengan resource yang digunakan oleh web service tersebut dan melakukan update secara periodik sehingga tercipta harga yang dinamis sesuai dengan QoS dari web service tersebut.Untuk itu dalam Tugas Akhir ini diimplementasikan sebuah web application yang menjadi broker dan penghubung antara provider dan service consumer dan menerapkan sistem pembiayaan berdasarkan QoS yang akan terupdate secara periodik.Kata Kunci : service provider, service requester, broker, publikasi web service, pricing web service, metering web service, QoS, Pay Per ClickABSTRACT: Web services technology is becoming an important technological trend in web application development and integration. Based upon open standards such as SOAP, WSDL, UDDI, and BPEL4WS, web services allow web-based applications to communicate through standardized XML messaging and to form loosely -coupled distributed systems. While web services technology provides a new computing model, in which infrastructures and application systems are hosted by service providers and made available to service consumers via web services, computing resources such as network bandwidth and storage throughput need to be allocated such that the total benefits of both the service providers and the service consumers are optimized subject to the QoS requirements of service requests. Therefore the main pupport from “pricing” in web service is to optimalize the benefit from bisnis operation that use web service, and it is do by using the QoS based pricing and update the price periodically so create the dinamic price according to QoS from that web service.Thus, in this final project will be implemented a web application in broker side and have a responsibilty as mediator between provider and consumer, and use the QoS based Pricing that updated periodically. This final project implementation will be developed using .NET Framework 1.1 and Visual Studio .NET 2003. Modeling is made in UML by using Rational Rose.Keyword: service provider, service requester, broker, publikasi web service, pricing web service, metering web service, QoS, Pay Per Click, provisioning

Vertical Platform Interaction on the Internet: How ISPS and CDNS Interact

Contend delivery networks (CDN) are important players on the Internet. They provide services towebsites that improve the quality of service (QoS) and provide end users (EU) with a betterexperience, i.e. faster loading web pages. CDNs can be seen as platforms that cater for two distinctgroups of customers. On the one side, they have content providers (CP), i.e. web sites; on the otherside they need to collaborate with Internet service providers (ISP) to reach EUs. We construct aformal model that demonstrates the pricing decisions of ISPs and CDNs and contrast it to thestandard types of pricing Internet access and traffic. As a modelling tool we use theory on two-sidedmarkets and bottleneck platforms. We find that ISPs have relatively high market power and extractprofits from CDNs to compete for EUs

A Review of the Operationalization of the ‘Some Free-Some Fee’ Service-Based Model by E-Content Web Sites

The Internet is a proven medium for information sharing and content dissemination and e-content sites flourished with the introduction of the World Wide Web. Initially these sites relied on Internet advertising as a means towards profitability but that proved to be short-sighted. In order for most e-content sites to be successful today, they must re-examine, modify and re-adjust their online business practices. One way to do this is to adopt a ‘some free-some fee’ services based model. In this model, content remains free but is enhanced with a collection of services to which fees are assessed. A review of e-content Web sites utilizing this model was undertaken and findings suggest variation in the types of services provided and the pricing structures employed

RFID-Integrated Retail Supply Chain Services: Lessons Learnt From The Smart Project

This paper proposes a service-oriented architecture that utilizes the automatic, unique identification capabilities of RFID technology, data stream management systems and web services, to support RFID-integrated supply chain services. In the lifespan of SMART project (IST-2005, FP6) two services have been deployed supporting dynamic-pricing of fresh products and management of promotion events. The two services have been field-tested in three retail stores in Greece, Ireland, and Cyprus. The valuable lessons learnt, concerning RFID readability challenges, consumer privacy, customers and store staff health concerns, investment cost, and so on, are reported to provide guidance to future developers of RFID-integrated supply chain services as well as to set an agenda for academic research
