How can IPv6 be flexible and adaptive for a broad range of services? How can IPv6 network adapt to the services specified requirements with high quality of experiences to users? How can IPv6 network simplify management for services? How can IPv6 network provide reliable services? This paper is an attempt to answer these questions and proposes IPv6 Virtual Network Architecture (VNET6) to support flexible services in IPv6 network. Different from other network architecture proposed in the past, VNET6 supports incremental network evolution and VNET6 is an idealized service-oriented network architecture based on IPv6 and virtualization technologies. IPv6 is a critical protocol in VNET6 and Virtual networks are built above network layer of IPv6 protocol stack. Virtualization in VNET6 aims to be a scale-out architecture using multiple entities to build a logical entity. This paper presents the details of virtual consolidation, virtual partition and virtual service. VNET6 supports different services and has many advantages such as service flexibility, simple manageability and high reliability. Giving example considerations of optimizing video experience, VNET6 is adaptive to video service with high bandwidth and low tendency and improves quality of experiences to users.","PeriodicalId":183800,"journal":{"name":"2012 International Conference on Cloud and Service Computing","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129702138","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}

It is also a business model, in which the service provider should try to make best use of resources, reduce energy consumption and earn profits as much as possible. Scheduling strategy plays an important role in service providing. A priority based algorithm for scheduling virtual machines on physical hosts in cloud computing environment is proposed. The target of this algorithm is to maximize the benefits of the service providers in the case of current resources are not enough to process all the requests in time. In this strategy, the requests are ranked according to the profits they can bring. Through the experiments, this approach has been proven it can increase the benefits than applying typical first come first serve strategy.","PeriodicalId":183800,"journal":{"name":"2012 International Conference on Cloud and Service Computing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129829026","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}

Meanwhile, the demands of different kinds of users are also rising sharply. In order to maximize the revenue, a proper pricing model is in desperate need. Nowadays, most of the providers are using static pricing which neglects the changes of supply and demand. Since the web services are easy to access and can be used by a large number of users, a dynamic pricing model aimed at maximizing the revenue is proposed. Our dynamic pricing model can automatically adjust the prices of resources according to the demands from users and the pricing for packages is based on Apriori Algorithm. Furthermore, the dynamic pricing model also can be adjusted and optimized by Genetic Annealing Algorithm so as to well adapt to the changes of Supply and demand. Compared with the static pricing model, the dynamic pricing model can increase the revenue to a considerable extent.","PeriodicalId":183800,"journal":{"name":"2012 International Conference on Cloud and Service Computing","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129201575","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}

Due to considerations on security, private data is usually protected by encryption before sending to cloud. How to utilize data efficiently while preserving user's privacy is a new challenge. In this paper, we focus on a efficient multi-keyword search scheme meeting a strict privacy requirement. First, we make a short review of two existing schemes supporting multi-keyword search, the kNN-based MRSE scheme and scheme based on bloom filter. Based on the kNN-based scheme, we propose an improved scheme. Our scheme adopt a product of three sparse matrix pairs instead of the original dense matrix pair to encrypt index, and thus get a significant improvement in efficiency. Then, we combine our improved scheme with bloom filter, and thus gain the ability for index updating. Simulation Experiments show proposed scheme indeed introduces low overhead on computation and storage.","PeriodicalId":183800,"journal":{"name":"2012 International Conference on Cloud and Service Computing","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115786238","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}

To address this challenge, we propose a context-aware collaborative filtering (CaCF) approach for service recommendation. Three types of contextual information, i.e. time, location and interest of user, are considered. In this approach, users' interests are extracted from service invocation records and represented as term-weight vectors. Neighbors are chosen according to the Cosine similarities of these vectors. Then, neighbors are filtered into close neighbors by location and time. At last, these close neighbors recommend service to a target user. We evaluate our method through comparing with other service recommendation approaches. The experimental results show that it achieves better precision and satisfaction rate than other two methods.","PeriodicalId":183800,"journal":{"name":"2012 International Conference on Cloud and Service Computing","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123663170","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}

There are a large number of organizations providing cloud computing infrastructure and services. In order to utilize these infrastructure resources and services, existing applications need to be migrated to clouds. However, a successful migration effort needs well-defined process support. It does not only help to identify and address challenges associated with migration but also provides a strategy to evaluate different platforms in relation to application and domain specific requirements. This paper present a process framework for supporting migration to cloud computing based on our experiences from migrating an Open Source System (OSS), Hackystat, to two different cloud computing platforms. We explained the process by performing a comparative analysis of our efforts to migrate Hackystate to Amazon Web Services and Google App Engine. We also report the potential challenges, suitable solutions, and lesson learned to support the presented process framework. We expect that the reported experiences can serve guidelines for those who intend to migrate software applications to cloud computing.","PeriodicalId":183800,"journal":{"name":"2012 International Conference on Cloud and Service Computing","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121097472","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, how to effectively and efficiently develop and deploy personalized SaaS and enterprise mashups on the cloud platforms remain a big research challenge. SaaS developers and researchers may adopt certain strategies by leveraging existing services available in the cloud and using model driven approach. They can compose and design new value-added services as on-demand SaaS and enterprise mashup applications deployed on cloud platform. In this paper, we propose an On-Demand Service-Oriented Model Driven Architecture (ODSOMDA) approach that involves adding Service Oriented Architecture (SOA) elements into MDA to realize the model transformation based on a Role&Goal-Process-Service (RGPS) meta-model. The meta-level analysis of MDA is applied to facilitate construction of SaaS and mashup applications through three-layer automatic (semi-automatic) model transformation. Finally, we develop an enterprise mashup prototype as a practical case study to prove the effectiveness of the proposed approach.","PeriodicalId":183800,"journal":{"name":"2012 International Conference on Cloud and Service Computing","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125948702","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}
