Only where NFPs have been specified can we choose between services with similar functionality that would better satisfy our non-functional requirements. Meanwhile, incorporating provenance functionality into service-oriented systems' design is becoming crucial for users, allowing them to query the generation methods and origins of the data the system outputs. This need is particularly evident in compositions of services, where audits of individual services do not provide a connected picture of the composition's processing history. Making provenance awareness (ability to answer provenance queries) an explicit NFP in composite service specifications would enable composite service designers to analyse whether they meet provenance-related requirements. In this paper, we discuss a framework for designing and analysing provenance awareness for service compositions. We envision this as a basis for analysing the impact of provenance on other NFPs such as performance and storage.","PeriodicalId":370898,"journal":{"name":"2013 IEEE International Conference on Services Computing","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124930223","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}

This is crucial if we are to improve the uptake and real-world effectiveness of service-based decision-support systems whilst also reducing the risks (both perceived and actual) of using such systems. This paper presents the current progress of the STRAPP project, which is designing and engineering novel trust and risk assessment mechanisms for services computing and applying these to a number of real-world service-based decision-support systems. A new layered architecture model for trust and risk is introduced and described in detail, and we present our state-of-the-art work in risk-assessment, demonstrating the relationship between provenance data and risk via a mathematical model. We then give a detailed description of our latest software demonstrator, integrated into the Rolls-Royce Equipment Health Management system, and comprehensively discuss the lessons we have learnt from developing such a complex, holistic, and applied real-world system. Finally, we describe the future work we plan to complete.","PeriodicalId":370898,"journal":{"name":"2013 IEEE International Conference on Services Computing","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121863156","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}

Many individuals and business organizations are beginning to move their data to cloud environments. It becomes increasingly important to investigate secure file storage in cloud environments. In this paper, we present a secure distributed file distribution system in which the customers can directly choose appropriate design parameters and service providers. In our scheme, we use novel coding techniques that almost achieve the Shannon information bound with very efficient coding and decoding process. Our evaluations show the correctness and efficiency of the coding scheme. We show that the problem to find the satisfying file distribution under certain cost and security constraints is NP-hard, and present the Satisfiability Modulo Theories (SMT) formalization to find the satisfying data share distribution with cost and security constraints. The SMT formalization is flexible to be applied to other threshold based cloud file distribution system and can accommodate other constraints. We also analyse the security of the scheme by defining the security metric (compromising probability) for both the eavesdropping and DoS attackers and show that one must carefully choose design parameters to achieve the required security.","PeriodicalId":370898,"journal":{"name":"2013 IEEE International Conference on Services Computing","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127228838","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 this paper, we study the horizontal scalability of n-tier application performance within a multicore processor (MCP). Through extensive measurements of the RUBBoS benchmark, we found one major source of performance variations within MCP: the mapping of cores to virtual CPUs can significantly lower on-chip cache hit ratio, causing performance drops of up to 22% without obvious changes in resource utilization. After we eliminated these variations by fixing the MCP core mapping, we measured the impact of three mainstream hypervisors (the dominant Commercial Hypervisor, Xen, and KVM) on intra-MCP horizontal scalability. On a quad-core dual-processor (total 8 cores), we found some interesting similarities and dissimilarities among the hypervisors. An example of similarities is a non-monotonic scalability trend (throughput increasing up to 4 cores and then decreasing for more than 4 cores) when running a browse-only CPU-intensive workload. This problem can be traced to the management of last level cache of CPU packages. An example of dissimilarities among hypervisors is their handling of write operations in mixed read/write, I/O-intensive workloads. Specifically, the Commercial Hypervisor is able to provide more than twice the throughput compared to KVM. Our measurements show that both MCP cache architecture and the choice of hypervisors indeed have an impact on the efficiency and horizontal scalability achievable by applications. However, despite their differences, all three mainstream hypervisors have difficulties with the intra-MCP horizontal scalability beyond 4 cores for n-tier applications.","PeriodicalId":370898,"journal":{"name":"2013 IEEE International Conference on Services Computing","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123439536","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}

However, existing personalization approaches, such as collaborative filtering or content based recommendations, are ignoring services' sociability because of the isolation of services without social relationships among them, and lacking of consideration of social influence. Therefore, there is a need for more accurate means to interlink them in a social-enhanced interest network, and to analyze and quantify the social influence. In this paper, we propose a methodology to connect distributed services into a global social service network for social influence-aware service recommendation, called recommend-as-you-go. First, we propose a novel platform to construct a global social service network by linking distributed services with social link using quality of social link, and then we propose a flexible model for effective awareness of social influence to provide a quantitative measure of the influential strength, Next, a novel social influence-aware service recommendation approach is presented based on global social service network, and finally, the experiment results show that our new approach can solve the quality of service recommendation problem well with quick query response, low usage threshold and high accuracy with user preferences by recommend-as-you-go.","PeriodicalId":370898,"journal":{"name":"2013 IEEE International Conference on Services Computing","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130881298","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}
