Each resource has its own set of configurable parameters that determine its overall health, viz., whether it would continue to function as designed. Any overloading of a resource in order to meet multiple tenancy requirements results in the system becoming \"unhealthy\", and therefore increasingly unfit to function normally. Typically, resources in a cloud environment are monitored using management tools such as IBM Systems Director and VMWare vSphere. While these tools do provide administrators with extensive information on the configurable parameters of monitored resources, they fail to provide a unified view on how \"healthy\" a resource is, especially when it is to be considered for provisioning a tenancy requirement. Such a lacuna usually forces systems administrators to make suboptimal guesses regarding the suitability of using the resource in question. To that end, in this paper, we discuss this crucial research issue and present our ongoing work on developing a provisioning health model for a resource, viz., its ability to meet a tenancy requirement taking into account its configurable parameters and current & past load conditions. We illustrate our model throughout our paper with a realistic running example, and discuss how our model could be developed and tested on reallife cloud environments.","PeriodicalId":409273,"journal":{"name":"2012 IEEE International Conference on Cloud Computing in Emerging Markets (CCEM)","volume":"225 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121305143","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}

One of the challenges with Virtualization Technology today is: delivering fast and scalable I/O bandwidth for virtualized servers. This paper will present various native I/O virtualization technologies (SRIOV, MRIOV and other proprietary ones) and describe how they will address the challenges presented by Server Virtualization. These emerging Hardware based I/O technologies can help IT organizations further increase consolidation ratios, virtualize a wider range of applications, and manage workloads more effectively by providing near to direct I/O access Performance as the I/O path length is comparable to a dedicated adapter assigned to a VM. . They also provide a necessary prerequisite for next-generation cloud computing models, which will ultimately deliver another major leap in data center efficiency through dynamic control of hardware. At the end, this paper will evaluate the advantages, limitations of native I/O Virtualization technologies.","PeriodicalId":409273,"journal":{"name":"2012 IEEE International Conference on Cloud Computing in Emerging Markets (CCEM)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126407155","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}

Such techniques are often useful in banking transactions, email creation, online surveys, data downloads etc. Starting from a very primitive stage of providing the users with a simple alphabetical string to asking using to do complex calculations, CAPTCHAs have come a long way in terms of sophistication of human-bot distinction. However in this process, these CAPTCHAs have lost their human friendliness, either because of the noise being added to the CATPCHA tests or because of the complications of the challenges thrown to the user resulting in bad experience. The traditional CAPTCHAs also fail to take into account the unique needs of the ubiquitous mobile devices. These mobile devices have few limitations like small display area, limited display resolution, color combinations of the display, processing power etc. Also, they have unique advantages of touch sensitive input devices, voice inputs, voice outputs etc. In this paper, we present a scheme for a CAPTCHA service on Cloud, which is specific to mobile application. We duly consider the need of usability and presentation that is required for a mobile device in our implementation. The proposed CAPTCHA framework offers scalable and flexible implementation opportunities in many verticals and domains. Another unique feature of our framework is that we provide the facility for distributed verification. This greatly improves the efficiency at the CATPCHA generation as well as reduces the response time for the user authentication as human.","PeriodicalId":409273,"journal":{"name":"2012 IEEE International Conference on Cloud Computing in Emerging Markets (CCEM)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128130141","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 collaborative clouds, the problem is compounded due to the fact that the tenancy requester would be completely unaware of the end cloud provider. As the tenancy requesters would not have established any negotiation terms with the end cloud provider, it is a complex challenge to ensure dependability in terms of trust, privacy and security of data exchanges. Existing approaches require establishment of point to point trust. However, in the larger context of possible collaborative cloud providers, there is a need for simplified trust management for tenants. Asking the tenants to exclusively establish trust relationships with each other hinders the choice of providers thereby restricting the dynamic collaborations. We propose an approach based on a model wherein a single security mediator is responsible for sharing the required trust with all involved cloud providers within the collaboration. This mediator acts as a hub for all the participant tenants. The tenants establish negotiation terms with the mediator. Whenever the tenancy request needs to be satisfied by a subsequent cloud provider, first a trust is established between the mediator and the new cloud provider. Once this level of trust is accepted and confirmed by the tenancy requester, this provider is added as a trusted provider and tenancy requests can be satisfied by this specific cloud provider.","PeriodicalId":409273,"journal":{"name":"2012 IEEE International Conference on Cloud Computing in Emerging Markets (CCEM)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133979482","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 is a an important change in the way these infrastructures are assembled, configured and managed. In this research we consider the problem of managing computing infrastructure which are acquired from Infrastructure as a service (IaaS) providers, which support the execution of web applications whose work load experience huge fluctuations over the time. The operating state of the web applications on the cloud is determined by the work load, service rate and utility gain of the web services, As these parameters are changing dynamically, we could not get the exact relationship between these parameters using conventional methods. We can use the Back propagation training algorithm of artificial neural networks to solve this problem. By training the Artificial neural network with the past data, we can estimate the future numbers. In this paper we proposed a artificial neural network based model that can be used for guiding the capacity planning activity. This paper reports on an investigation on the application of ANNs in Capacity planning of cloud based infrastructure. A multi-layer feed-forward artificial neural network (ANN) with error back-propagation learning is proposed for calculation of number of reserved instances for future use. Matlab Neural Network Toolbox is used for simulation of required ANN and considering Amazon web services as a IaaS provider.","PeriodicalId":409273,"journal":{"name":"2012 IEEE International Conference on Cloud Computing in Emerging Markets (CCEM)","volume":"103 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116520170","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}
