“…The platform AppExchange by Salesforce offers over 1,100 services that can be integrated directly within the customers' CRM processes on Sales Cloud (cf. Weinhardt et al 2011). The realization of SOA through the standardized technology of (web) services (Alrifai et al 2012) as well as its characteristics (loose coupling, dynamic binding, open standards, simplicity, and security) (Erl 2009) open up the possibility of versatile and flexible ad-hoc collaborations between different business partners (Luthria and Rabhi 2009;Ren and Lyytinen 2008).…”

Quality-of-Service-Aware Service Selection: A Novel Approach Considering Potential Service Failures and Nondeterministic Service Values

In service oriented systems, a variety of loosely coupled services are composed to support the execution of processes. One important research question in this context is, how such services can be selected by taking into account the values for the corresponding quality-of-service (QoS) attributes. Existing QoS-aware ex-ante service selection approaches build on preferences and requirements for the QoS attributes and evaluate the available services by means of a utility value. Due to many reasons like software bugs, high server workload or network failures an exante optimal service may temporarily be unavailable or fail during its execution, requiring replanning. Moreover, several QoS attribute values may be stochastic rather than deterministic.Thus, both the ex-post realized QoS values and the corresponding utility may significantly differ from the ex-ante computed ones, incurring a substantial loss of resources. In this paper we present a novel approach for the QoS-aware service selection considering both the effects of potential service failures and non-deterministic QoS values ex-ante. The approach is founded on an expected utility calculus. We find that considering the effects of potential service failures and non-deterministic QoS values leads to substantially better decisions in QoS-aware service selection.

“…Kantere et al (2011) has proposed a novel pricedemand model for a cloud cache. They also proposed dynamic pricing scheme for queries executed in the cloud cache (Weinhardt et al, 2011).The users can query the cloud data and pay the price for the infrastructure they use. The goal of this study is to optimize the user satisfaction and cloud profit.…”

“…The first is to define a pricing model that is based on users' demand and second is to define an adaptable pricing scheme with flexibility forcorrections. Weinhardt et al (2011) proposed different types of pricing schemes: static, flexible and dynamic and have discussed how these could be applied to web services (Ruiz-Agundez et al, 2011). Flexible pricing is realized by price discrimination and divided into Personalized Pricing, Self-Selection and Group Pricing.…”

Problem statement: Metering and charging are basic accounting functions that are essential for commercial usage of web services. Current charging and accounting schemes primarily involve users being charged flat or based on the connection/session time. Accounting management of web services should provide for metering, charging, accounting, billing, payment and auditing. We have extended our earlier work, a Policy based Accounting for Web Services (WS-PACT), to develop a generic and comprehensive charging policy that can cater to different charging patterns. WS-PACT provides a flexible model to meet the varying billing and payment needs of service providers. Approach: Policies are expressed in WS-Policy and policy query facility has been developed using XQuery. Results: Users can use the query facility to obtain the charges being levied and can decide on which services to use by taking into account their preferred spending limits and payment patterns. Conclusion: We have implemented and tested the charging policy and query facility with a sample application.
