Profit Aware Load Balancing for Distributed Cloud Data Centers

Abstract: The advent of cloud systems has spurred the emergence of an impressive assortment of Internet services. Recent pressures on enhancing the profitability by curtailing surging dollar costs on energy have posed challenges to, as well as placed a new emphasis on, designing energy-efficient request dispatching and resource management algorithms. What further adds to the design challenge is the highly diverse nature of Internet service requests in terms of Quality-of-Service (QoS) constraints and business values. Nonetheless, most of the existing job scheduling and resource management solutions are for a single type of request and are profit oblivious. They are unable to reap the benefit of multi-service profit-aware algorithm designs. In this paper, we consider a cloud service provider operating geographically distributed data centers in a multi-electricity-market environment, and propose an energy-efficient, profit-and cost-aware request dispatching and resource allocation algorithm to maximize a service provider's net profit. We formulate the net profit maximization issue as a constrained optimization problem, using a unified task model capturing multiple cloud layers (e.g., SaaS, PaaS, IaaS.) The proposed approach maximizes a service provider's net profit by judiciously distributing service requests to data centers, powering on/off an appropriate number of servers, and allocating server resources to dispatched requests. We conduct extensive experiments to validate our proposed algorithm. Results show that our proposed approach can improve a service provider's net profit significantly.

Situated Software: Concepts, Motivation, Technology, and the Future

Abstract: Situated software, a type of opportunistic software, is created by a small subset of users to fulfill a specific purpose. For example, business users have been creating situated software through mashups, which combine data from multiple sources on internal systems or the Internet. Situated software can change the way users access, perceive, and consume information, and can allow users to finally focus on what to do with information, rather than where to find it or how to get to it. However, situated software also has limitations. This article identifies situated software's role, provides examples of its use, traces the Internet's role in its rapid evolution, outlines areas where it is appropriate, describes its limitations, and presents enablers for adopting situated software in an enterprise.

Computer software and services license processing method and system

Abstract: Integrated computer services and software licensing processing methods and systems are provided A license processing service (LPS) receives a services or software license request from a user via a client computer The LPS communicates the request to a billing system for the services or software provider to obtain an expiration date for use of a desired service or software product The LPS receives and forwards the expiration date from the billing system to a licensing clearinghouse operated by the provider of the desired service or software product The clearinghouse, in turn, provides a use license for the desired service or software application to the client computer via the LPS

Block chain-based online taxi-hailing service system

Abstract: The invention discloses a block chain-based online taxi-hailing service system. The system includes a traffic cloud database, a traffic cloud artificial intelligence system (TAI) and a mobile client. With the block chain-based online taxi-hailing service system adopted, a decentralized, trustless, collectively maintained, asymmetric cryptography reliable database basic infrastructure and underlying internet protocol can be provided for traffic cloud; and a mobile SaaS (Software-as-a-Service) application pattern, a distributed computing normal form and a group intelligence model which can establish high-degree connections for travelers based on time stamp, achieve travel resource allocation consensuses and provide services according to demands can be realized.

Cloud Computing Benefits for Educational Institutions

Abstract: Education today is becoming completely associated with the Information Technology on the content delivery, communication and collaboration. The need for servers, storage and software are highly demanding in the universities, colleges and schools. Cloud Computing is an Internet based computing, whereby shared resources, software and information, are provided to computers and devices on-demand, like the electricity grid. Currently, IaaS (Infrastructure as a Service), PaaS (Platform as a Service) and SaaS (Software as a Service) are used as business model for Cloud Computing. The paper also introduces the cloud computing infrastructure provided by Microsoft, Google and Amazon Web Service. In this paper we will review the features the educational institutions can use from the cloud computing providers to increase the benefits of students and teachers.
