Accumulation of anomalies of different nature, such as memory leaks and unterminated threads, may lead the system to both fail or work with suboptimal performance levels. This problem particularly affects web servers, where hosted applications are typically intended to continuously run, thus incrementing the probability, therefore the associated effects, of accumulation of anomalies. Given the unpredictability of occurrence of anomalies, continuous system monitoring would be required to detect possible system failures and/or excessive performance degradation in order to timely start some recovering procedure. In this paper, we present a Machine Learning-based framework for proactive management of client-server applications in the cloud. Through optimized Machine Learning models and continually measuring system features, the framework predicts the remaining time to the occurrence of some unexpected event (system failure, service level agreement violation, etc.) of a virtual machine hosting a server instance of the application. The framework is able to manage virtual machines in the presence of different types anomalies and with different anomaly occurrence patterns. We show the effectiveness of the proposed solution by presenting results of a set of experiments we carried out in the context of a real world-inspired scenario.","PeriodicalId":309782,"journal":{"name":"2015 IEEE Fourth Symposium on Network Cloud Computing and Applications (NCCA)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122417562","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 concentrate on managing physical host nodes in DDVMC strategy and propose a cooperative multi-agent learning paradigm to make optimal decisions towards energy and performance efficiency in cloud data centers. Our approach is also able to assure scalability due to increasing the number of hosts in the data center. The experimental results show that our approach yields far better results w.r.t. the energy-performance tradeoff in cloud data centers in comparison to state-of-the-art algorithms.","PeriodicalId":309782,"journal":{"name":"2015 IEEE Fourth Symposium on Network Cloud Computing and Applications (NCCA)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132150257","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}

Today accruing harvest labors is still done by hands, which is error-prone and costly. By integrating cloud-based web application with purposely designed labor monitoring devices (LMDs), we developed a harvest management system for monitoring and accruing harvest labors. The system comprises of two major components: an in-orchard data collection network collecting harvest data and transmitting them to a cloud-based labor management software (LMS); and, LMS processing harvest data and delivering results to users via a tablet-friendly web interface. Using a patented technology, the system accurately accrues harvest labor activities for multiple orchards, even under complex many-to-many employment relations. The system provides multi-fold benefits to stakeholders of specialty crop harvesting: a picker can be compensated accurately by the actual weight of the fruits he picked; and an orchard manager may monitor labor activities in real time and improve his orchard operation based on the analytical reports generated by the system. The dynamic resource allocation provided by a cloud computing platform ensures that the system can handle the fluctuating demand for processing real-time harvest data during and off harvest seasons. The design of the system is optimized for cloud computing, improving the access to orchard data while preserving their privacy for growers. A prototype of the system has been validated in field tests in United States' Pacific Northwest Region.","PeriodicalId":309782,"journal":{"name":"2015 IEEE Fourth Symposium on Network Cloud Computing and Applications (NCCA)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116737264","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 particular, SDI will be highly dynamic and pervasive environments of logical resources capable of executing any network and service function (e.g., from L2 to L7) developed and controlled as software applications. It is argued that SDI will be a first concrete impact of the Softwarization trend which is starting to impact (with different expressions, e.g., SDN, NFV, Cloud and Network Computing) the Telecommunications and ICT ecosystems.In this respect, the paper proposes the model of the Universal Operating System (UOS) for SDIs as an overarching and distributed Operating System spanning from terminals through the network elements, to the Cloud/IT resources. Then UOS functional architectures and some key challenges related to its development are briefly examined.Eventually, it is argued that this evolution towards SDI will definitely blur, on one side the border between the Telecommunications networks and the Cloud Computing, and, on the other side, the distinction between the Telecommunications networks and the future \"terminals\" connected to them (e.g., handsets, tablets, machines, smart things, drones, robot). This transformation will have profound techno-economic implications for the Telecommunications and ICT ecosystems.","PeriodicalId":309782,"journal":{"name":"2015 IEEE Fourth Symposium on Network Cloud Computing and Applications (NCCA)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124827220","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}

The success of such deployments very much depends on the design and implementation of essential, secure mechanisms for authentication, authorization, and accounting (AAA) that not only ensure the robustness of such facilities against intrusions and unauthorized use but also ease experimentation and system administration in such complex environments. C-BAS is an initiative in this direction that uses a secure and flexible certificate-based AAA architecture for SDN experimental facilities. Advanced certificate-based authentication and authorization makes C-BAS inherently resilient against attacks specific to traditional AAA mechanisms, increases flexibility and autonomy in experimental facility system administration, and facilitates federation. This article introduces the implementation details of C-BAS, explains its features through use cases, and evaluates its computational performance.","PeriodicalId":309782,"journal":{"name":"2015 IEEE Fourth Symposium on Network Cloud Computing and Applications (NCCA)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123080343","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}
