In this paper, we deal with the problem of adaptive dispatching (distribution) of resources in a cloud computer environment (CCE). In particular, the CCE comprises heterogeneous computational resources and we consider the implementation of a flow of large-scale scientific tasks consisting of a set of information-dependent subtasks that enter the CCE at random times. We present an effective method...
Graph analytics has become essential to uncover relationship insights in complex systems. As graphs grow in scale, several graph-parallel frameworks including Pregel, GraphLab, and PowerGraph are developed based on commodity computers and/or Cloud instances. According to recent research and empirical performance evaluation, system optimization on PowerGraph allow it to outperform others significantly...
With enterprises collecting feedback down to every possible detail, data repositories are being over flooded with information. In-order to access valuable information, these data should be processed using sophisticated statistical analysis. Traditional analytical tools, existing statistical software and data management systems find it challenging to perform deep analysis upon large data libraries...
Cloud computing is an emerging technology which enables the cloud users to access the computing resources without having to pay huge capital expenses to scale up the IT infrastructure and reduces the management cost, in both hardware and software. A cloud introduces a resource rich computing model with features such as flexibility, pay per use, elasticity, scalability, and others. In this context,...
Today's world is an era of information technology in which cloud computing arises as promising and developing technology. In cloud computing environment the resources are provisioned on the basis of demand, as and when required. In cloud computing a large number of cloud users can request a number of cloud services at the same time. So there must be an efficient way in which all the resources are...
Antivirus is most widely used to detect and stop malware and other unwanted files. Cloud antivirus is a malware detector architecture where virus definitions and other behaviors of suspicious files is analyzed on cloud and controlled by a light weight Agent on client system. We suggest using two-way caching scheme where local-cache is stored on client system and cloud-cache is present on network cloud,...
As cloud computing is found everywhere in current scenario. From large scale organization to small scale business everyone moving towards cloud. Because of its simplicity, monitoring and maintenance over remote connection, large area coverage. Cloud can be any type Software as a service, platform as a service, infrastructure as a service based on its usage. In infrastructure as a service virtualization...
Cloud computing being promising and emerging technology for the next generation of IT applications which provides the storage and supports for outsourcing of data without having the native copy of data or files. Cloud computing service providers require a system which can handle a large number of requests at a time and is needed to be highly available. Major issue faces in cloud computing is Security...
Services involving cloud computing are advertised by the providers such that they are available all the time; but many of the recent past events have shown how a single or a bunch of component seizures can lead to a system failure affecting the business continuity of consumers. Though reliability of a cloud system depends heavily on the capability of the participating components as a whole, but there...
Constant changes are inherent to information technology, the proof of which can be found in many challenges, such as the business sector's cloud computing. Because of the recent economic and financial crisis companies are forced to provide as best results as possible with the least amount of costs. The main issue of cloud computing are the computer resources (i.e. compute power). Due to their less...
The paper describes the technical characteristics of private cloud applying into the digital community. According to the current developing tendency of digital community around the world, it is necessary and practical of carrying out digital community based on private cloud. On the analysis of private cloud, there are many aspects applied in the digital community such as construction planning, property...
There is an increasing demand for smart fog-computing gateways as the size of cloud data is growing. This paper presents a Fog computing interface (FIT) for processing clinical speech data. FIT builds upon our previous work on EchoWear, a wearable technology that validated the use of smartwatches for collecting clinical speech data from patients with Parkinson's disease (PD). The fog interface is...
The models for logical controlling of global computational processes in computer networks with agent-oriented cloud metacomputing services based on collective data transferring were proposed in this article. This allows simplifying of the implementation of massive parallelism in large-scale applied distributed systems. Using of the formalism of asynchronous predicate networks was proposed to control...
The proliferation of smart mobile devices and their increasing traffic demands has resulted in the density of 802.11/WiFi networks being pushed to the limit. As such, WiFi virtualization has been positioned as a solution to accommodate and improve future communications, with many frameworks, protocols and algorithms being developed for virtualized networks. This work develops an experimental platform...
The life-science and health care research environments offer an abundance of new opportunities for improvement of their efficiency and productivity using big data in collaborative research processes. A key component of this development is e-Science analytics, which is typically supported by Cloud computing nowadays. However, the state-of-the-art Cloud technology does not provide an appropriate support...
IBM is one of the top companies in technology and business field, the aim of the research is to measure the awareness gauge of computer science students and graduates about some of the main IBM cloud solutions which are IBM Bluemix, and Watson Analytics in Saudi Arabia. The method used in the research to measure the awareness was publishing both online and paper surveys. The surveys got a total of...
In recent days Cloud services such as storage is more familiar to business and Individuals. This storage services are found as a problem to examiners and researchers in the field of forensics. There are many kind of storage services available in cloud and every service face a diverse issues in illegitimate action. The evidence identification, preservation, and collection are hard when dissimilar services...
Benefited from cloud storage services, users can save their cost of buying expensive storage servers. Meanwhile they lost the physical control of their data. So effective methods are needed to verify the correctness of the data stored in cloud servers, which are the research issues the provable data possession (PDP) faces. This paper analyzes the existing PDP algorithms, finds some defects of these...
Cloud network system will meet the military demand on sea battlefield more effectively. Taking cloud computing as the core, the conception of sea battlefield cloud network has been presented. Combat cloud from it can strengthen the capability of collaborative combat in sea battlefield. Then, infrastructure of sea battlefield cloud network is constructed according to the tactics needs on sea battlefield...
The adoption of cloud computing is increasing and its use is becoming widespread in many sectors. As the proportion of services provided using cloud computing increases, legal and regulatory issues are becoming more significant. In this paper we explore how an Information Flow Audit (IFA) mechanism, that provides key data regarding provenance, can be used to verify compliance with regulatory and contractual...
