Adoption of cloud yields several benefits to the consumer and these benefits could be realized to their fullest potential in a market based mechanism. At present, commercial marketplaces for cloud-based services are in their infancy. Nevertheless, we are gradually moving towards marketplaces like Amazon AWS. In future, electronic agents would negotiate on the behalf of consumers in procuring a service from cloud markets. In negotiating a cloud-service, the agents should be capable of representing their principals' preferences. These preferences help the agents to improve the outcome of a negotiation. The possibility of a successful outcome can be enhanced by exploiting trade-offs that are driven by preferences among multiple issues. One such preference is time preference which can modeled using time discount functions and is useful in generating price and time trade-offs. In this paper, we propose a hyperbolic discounting model based on the theory of intertemporal choice to generate price and time trade-offs. Further, we provide an algorithm to integrate hyperbolic discounting function based trade-off model with a time dependent tactic (TDT) based concession model in the negotiation process.","PeriodicalId":138078,"journal":{"name":"2012 International Symposium on Cloud and Services Computing","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121734317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In infrastructure providers (Amazon EC2, Rack Space etc.) The Virtual Machine (VM) size is static. Depending on the capacity of the VM the prices are fixed and pay as you go model is used. Since the VM size is static there is a high possibility of mismatch between application resource requirement and VM capacity. If the VM capacity is more than the application requirement, even though user is not utilizing the entire VM capacity he will be unnecessarily paying the extra money and also in this case resource utilization is not efficient. If the VM capacity is less than the application requirement then the application performance will degrade. With this motivation this work presents a prediction based dynamic configuration framework for virtual machines which predicts the required computing resources of the application and configures the VM as per the application requirement. To capture the characteristic of cloud application RAIN (which is a workload generation toolkit) has been used. To evaluate our prediction model we are using Olio which is a cloud benchmark application. With our approach an average error rate of 8% - 10% is observed.","PeriodicalId":138078,"journal":{"name":"2012 International Symposium on Cloud and Services Computing","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129885254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nandhini","doi":"10.1109/ISCOS.2012.13","DOIUrl":"https://doi.org/10.1109/ISCOS.2012.13","url":null,"abstract":"Today organizations in all industries particularly financial services, retail and communications are increasingly dependent upon IT and a highly available network to meet their business objectives. As customer expectations and demands rise, network operations teams are focusing on IT service-quality improvement and achieving higher levels of availability by re-examining processes and procedures particularly in the area of change management because changes to the network are often a source of downtime. Growing complexity of customer needs is one of the prevailing problems faced by IT enterprises at present, leading to increasingly complex IT service management systems. At the same time, quick response to unexpected problems and externally imposed requirements are testing the IT change management. Although there exists many change management issues and solutions, there is no proper support for efficient change evaluation and monitoring. Present change management works are done only in the web service interface such as WSDL Web Service Definition Language and there is no proper support for dynamic nature in them. In order to provide a flexible environment for the Business Analyst to perform the emergency changes over the service business logic without the need of IT staff and also to evaluate changes made, we propose a Finite State Machine based Evaluation Model for Web Service Runtime Change Management and also a set of change factors to evaluate runtime changes of web services. Among which we mainly focus on the factor Business Policy Enforcement which is used for checking whether there is any policy violation with respect to the changes made. We first define the various change factors and derive a mathematical solution for each one. The derived solution is considered as the change measure for individual change factor. A case study from banking domain is provided to validate the proposed framework.","PeriodicalId":138078,"journal":{"name":"2012 International Symposium on Cloud and Services Computing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131168399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
