Cloud computing is becoming a key element in service provision on the Internet. Businesses are seizing the availability of infrastructure as service to obtain cost effective infrastructure solutions. However, in businesses the power of services emerges from the ability to combine different services in order to obtain some value added services. Cloud services composition presents some challenges like,...
Over the Internet, e-Learning has speeded up the knowledge transfer without restrictions on time and space in recent years. In order to achieve the goal of knowledge sharing and reusing interactively, lots of available e-Learning standards have been adapted to complete this purpose. Normally, learning objects meeting these standards are sharable with other e-Learning platforms. Most e-Learning platforms,...
Cloud computing is one of the emerging technologies that will lead to the next generation of Internet. It provides optimized and efficient computing through enhanced collaboration, agility, scalability, and availability. In this paper, the evolution of the Cloud is discussed, the cloud computing model is explained, a set of cloud computing infrastructure metrics is listed, the cloud service model...
The following topics are dealt with: distributed and parallel computing; semantic Web; mobile networks; peer-to-peer computing; sealable computing; Internet; opportunistic and delay tolerant networks; agent and dependable systems; intelligent computing; communication networks; service oriented architecture; security; wireless sensor networks; privacy; ad hoc networks; life science modeling and computing;...
The combination of cloud computing, ad hoc networking and proliferation of wireless devices and sensors will be the most significant disruptive technology to transform the way next generation services are supplied and consumed in the communications industry since the introduction of Internet. In this next generation service marketplace, service brokering is emerging as a promising low-risk business...
Mobile devices are now equipped with multiple sensors and networking capabilities. They can gather information about their surrounding environment and interact both with nearby nodes, using a dynamic and self-configurable ad-hoc network, and with distant nodes via the Internet. While the concept of mobile agent is appropriate to explore the ad-hoc network and autonomously discover service providers,...
In this work we present a novel concept for satellite based cloud computing integrating virtualized information resources from satellites and from the Internet. We first discuss the role of satellites in the infrastructure of cloud computing. Second we focus on some practical aspects of cloud computing, considering different configurations for access to satellite channels. We follow with reporting...
Recently, Cloud computing has emerged as a new computing paradigm on the Internet. Cloud computing facilitates flexible and efficient computer resource management via virtualization technologies at anytime and from anywhere, so that users can add and/or delete IT resources. Users can set up and boot the required resources and they have to pay only for the required resources. However, they have to...
We introduce WordBridge, a novel graph-based visualization technique for showing relationships between entities in text corpora. The technique is a node-link visualization where both nodes and links are tag clouds. Using these tag clouds, WordBridge can reveal relationships by representing not only entities and their connections, but also the nature of their relationship using representative keywords...
This article describes internet-based application for warehouse management written in Ruby with use of Ruby on Rails framework and distributed as Software as a Service (SaaS) platform. This approach allows for great compatibility between operating systems as well as makes it possible to access application from all kind of devices - from standalone desktop computers up to tables and all kind of mobile...
In this paper, we present an online application service system which includes a SaaS platform server. We applied code generation and metadata model technology in order to serve multiple tenants with a single instance of web based online application.
This paper deals with a new concept of Internet and TV convergence which has been verified by the implementation of a laboratory demonstrator. Based on a social network focused on TV issues a broad scope of TV features is provided for a variety of end systems.
Modern production clusters are often shared by multiple types of jobs with different priorities in order to improve resource utilization. Preemption is a common technique employed by MapReduce schedulers to avoid delaying production jobs while allowing the cluster to be shared by other non-production jobs. In addition, it also prevents a large job from occupying too many resources and starving others...
Virtualization technology is popular today for hosting Internet and cloud-based compute services. Recently, the IP Communications domain has seen the adoption of virtualization with enterprise telephony solutions being hosted in virtualized environments. A deployment scenario that is common in the IP communications domain is the virtual appliance. A virtual appliance encapsulates the IP Telephony...
Grid computing emerged as a computing paradigm to take advantage of the enormous availability of computing and communication resources in the Internet. Cloud computing succeeded grid computing as a new computer paradigm, offering resource transparency to the computation of user demands. In cloud computing, virtualization techniques are central to the provisioning of resources in clouds. This paper...
The proliferation of Data as a Service (DaaS) available on the Internet and offered by cloud service providers indicates an increasing trend in providing data under Web services in e-science and business domains. While data usage and selection are dependent on different constraints established on the basis of several data concerns, for example, quality of data and data privacy, existing data service...
Cloud computing is a buzzword terminology applied to several nascent trends in the turbulent landscape of information technology. Computing in the "cloud" alludes to ubiquitous and inexhaustible on-demand IT resources accessible through the Internet. In the era of cloud computing, whole lifecycle of telecommunication services, especially service deployment, present new features. In this...
We consider geographically distributed data centers forming a collectively managed cloud computing system hosting multiple applications, each subject to Service Level Agreements (SLA). The Service Level Agreements for each application require the response time of a certain percentile of the input requests to be less than a specified value, with the non-conforming requests being charged a penalty....
By adopting the idea of insurance business in our real life, an insurance-based cloud computing architecture is proposed in this paper to rebuild a monetary credit system for cloud computing. In this architecture, insurer agents are introduced to offer paid guarantee for services in cloud computing, and to compensate Internet users when the services invoked fail. Then, regarding to the bankrupt risks...
Traditionally, computing infrastructure has been a substantial burden for companies. But what happens when business are unchained from their physical infrastructure and allowed to focus on business goal? The model of infrastructure as a service and cloud computing bring us closer to this possibility. In this paper we discussed the growth of the web based service industry. The myriad of service now...
