The drastic increase in the commodity computer and network performance for the last generation has a resultant of faster hardware and more sophisticated software. But, the supercomputers of the current generation are still incapable of solving the current problems in the field of science, engineering, and business. This problems arises as a single machine cannot facilitate the availability of various...
Cloud Computing has been widely used by Customers to outsource IT services and business applications managed by a third-party called Cloud Provider in order to reduce their equipment management costs. The academic sector have also taken notice and are investigating how Cloud technology can provide results more quickly and at lower cost in order to deploy Grid services which benefit already from distributed...
Cloud computing has materialized as a new platform in the field of Computer Science. Its focus is on providing different facilities through its flexible infrastructure. With its vast capabilities, the cloud has expanded itself into various applications. In this paper, we have surveyed 15 papers on cloud computing; analyzing its history, development and future aspects. Our paper summarizes how the...
In recent years a new concept, called “mobile cloud computing” (MCC), has been put forward, it can build more powerful mobile cloud applications, and it is considered as one of the most highly discussed topics in terms of both academic community and computing industry. In this paper, we aim to understand why mobile computing chooses cloud computing as an external source. Thus, this paper presents...
The long-dreamed vision of “computing as a utility” has finally taken shape in the form of cloud computing. This paradigm shift is the biggest buzz in today's computer world. It can be thought of an evolution of existing technologies rather than a revolution. The basic requirements of cloud are to meet the various needs of enterprise organizations such as scalability, adaptability, extensibility and...
We address the problem of usage license administration in federated settings. This problem arises whenever organizations, such as educational or research groups or institutions, share resources for business and scientific reasons. In such settings, each user's usage of a licensed resource is typically supported by the user's organization. License administration involves satisfying legal requirements...
Both grid and cloud are used to organize large scale calculations and data processing on remote computers. Grid which became a basic computing infrastructure for the Large Hadron Collider experiments provides unified technical solutions for sharing and merging distributed heterogeneous computing resources within big collaboration groups. Cloud became popular among data centers and computing service...
Cloud computing, despite its hype, is being widely deployed, with its dynamic scalability and usage of virtualized resources, in many organizations for several applications. It is envisioned that, in the near future, cloud computing will have a significant impact on the educational and learning environment, enabling their own users (i.e., learners, instructors, and administrators) to perform their...
This paper presents a Sandbox model for desktop grid and cloud computing (PaaS). The model uses an approach where the access rules are organized by three elements: Domain Security Manager (DSM), entity and task. Each one has a hierarchical organization where the rules of a specific level are posted upon that defined in the superior level, allowing a high flexibility in the access policies management.
Cloud Computing is catching more attention around the world with its excellent features in providing the services and advantages in economy both for the end-users and Cloud providers. However, due to lack of enough resources, Cloud vendors currently can only provide general resources and services, like computing as a service but not suitable for research on specific domain. Grid Computing, on the...
In this paper, we investigate how Service Level Agreeements (SLAs) can be incorporated as part of the system's scheduling and rental decisions to satisfy the different performance promises of high performance computing (HPC) applications. Such SLAs are contracts which specify a set of application-driven requirements such as the estimated total load, contract duration, total utility value and the estimated...
Many believe that Cloud will reshape the entire ICT industry as a revolution. In this paper, we aim to pinpoint the challenges and issues of Cloud computing. We first discuss two related computing paradigms - Service-Oriented Computing and Grid computing, and their relationships with Cloud computing. We then identify several challenges from the Cloud computing adoption perspective. Last, we will highlight...
In this paper, a Metascheduler architecture is proposed to be used on Cloud Computing environments. The aim of this Metascheduler architecture is to handle the submission of a service and to manage the infrastructure of the Grid resources belonging to the Cloud. Futhermore, this Metascheduler also aims of building the best pool of available resources for the implementation of the requests issued by...
Along with the up-rising of knowledge economy, effective organizing multiple, distributed, heterogeneous knowledge resource and providing high-quality knowledge services for users have been becoming increasingly important. This paper proposes a novel concept of intelligent topic map for knowledge organization and knowledge services, which embodies the multi-level, multi-granularity and inherent relevant...
