Business Intelligence (BI) has gained a new lease of life through Cloud computing as its demand for unlimited hardware and platform resources expandability is fulfilled by the Cloud elasticity features. BI can be seamlessly deployed on the Cloud given that its multilayered model coincides with the Cloud multilayer models. It is considered by many Cloud service providers as one of the prominent applications services on public, outsourced private and outsourced community Clouds. However, in the shared domains of Cloud computing, BI is exposed to security and privacy threats by virtue of exploits, eavesdropping, distributed attacks, malware attacks, and such other known challenges on Cloud computing. Given the multi-layered model of BI and Cloud computing, its protection on Cloud computing needs to be ensured through multilayered controls. In this paper, a multi-layered security and privacy model of BI as a service on Cloud computing is proposed through an algorithm for ensuring multi-level session inspections, and ensuring maximum security controls at all the seven layers, and prevent an attack from occurring. This will not only reduce the risk of security breaches, but allow an organisation time to detect, and respond to an attack. The simulations present the effects of distributed attacks on the BI systems by attackers posing as genuine Cloud tenants. The results reflect how the attackers are blocked by the multilayered security and privacy controls deployed for protecting the BI servers and databases. Copyright © 2020, The Authors.

Cloud computing is a generic term for delivering hosted services over the Internet. It follows a pay-as-you-go approach. Cloud computing offers numerous benefits for the enterprises, however, there are also many issues, as with any new paradigm or technology. One of the main issues relate to the security and confidentiality of customer data in terms of its location, relocation, availability and security. This paper outlines the Cloud benefits, briefly explains the delivery and deployment models and discusses in detail the issues relating to data in the Cloud. The aim is to provide some useful background information for organizations preparing to migrate to the Cloud to take advantage of this latest computing paradigm.

Cloud BI: Future of business intelligence in the cloud

arXiv

引用

arXiv 2019年

Cloud computing is gradually gaining popularity among businesses due to its distinct advantages over self-hosted IT infrastructures. Business Intelligence (BI) is a highly resource intensive system requiring large-scale parallel processing and significant storage capacities to host data warehouses. In self-hosted environments it was feared that BI will eventually face a resource crunch situation because it will not be feasible for companies to keep adding resources to host a never ending expansion of data warehouses and the online analytical processing (OLAP) demands on the underlying networking. Cloud computing has instigated a new hope for future prospects of BI. However, how will BI be implemented on cloud and how will the traffic and demand profile look like? This research attempts to answer these key questions in regards to taking BI to the cloud. The cloud hosting of BI has been demonstrated with the help of a simulation on OPNET comprising a cloud model with multiple OLAP application servers applying parallel query loads on an array of servers hosting relational databases. The simulation results have reflected that true and extensible parallel processing of database servers on the cloud can efficiently process OLAP application demands on cloud computing. Hence, the BI designer needs to plan for a highly partitioned database running on massively parallel database servers in which, each server hosts at least one partition of the underlying database serving the OLAP demands.

Using a dual EEG set-up, pairs of subjects jointly performed finger movement tasks under three conditions: intrinsic-ignore;in-phase - follow;and anti-phase - oppose their partner's movement patterns. Group ICA was employed for signal decomposition in the 10-12 Hz range. Mutual information across dyads was estimated in tasks relative to baseline. Results demonstrated information encoding (between partners) in the anti-phase was two times more than the intrinsic which in turn expressed twice as much information content as the more automatic in-phase task. Topography of significant components revealed involvement of the frontal brain region in the intrinsic;both frontal and occipital brain regions in anti-phase suggesting decision making and employment of visual resources in these tasks. © 2012 IEEE.

In packet-switched networks, queueing of packets at the switches can result when multiple connections share the same physical link. To accommodate a large number of connections, a switch can employ link-scheduling algorithms to prioritize the transmission of the queued packets. Due to the high-speed links and small packet sizes, a hardware solution is needed for the priority queue in order to make the link schedulers effective. But for good performance, the switch should also support a large number of priority levels (P) and be able to buffer a large number of packets (N). So a hardware priority queue design must be both fast and scalable (with respect to N and P) in order to be implemented effectively. In this paper, we first compare four existing hardware priority queue architectures, and identify scalability limitations on implementing these existing architectures for large N and P. Based on our findings, we propose two new priority queue architectures, and evaluate them using simulation results from Verilog HDL and Epoch implementations.

In the past decade, Peer-to-Peer (P2P) systems achieved great successes. Its fascinating characteristics, such as decentralized control, self-governance, fault tolerance and load balancing, make it the default infrastructure for file sharing applications. Today, P2P system is one of the largest Internet bandwidth consumers. In order to relieve the burden on Internet backbone and improve the user access experience, efficient caching strategies should be applied. In this paper, we propose a novel collaborative caching in P2P streaming systems. This strategy first calculates the factor of each cached file through their caching value, and then replaces the file with the lowest factor. The simulation experiments show that our strategy has higher cache hits and lower system load. © 2018, Springer Nature Switzerland AG.

Changes will be required to handle the increased power flow in the network as the distribution infrastructure ages and the number of EVs and renewable grows. Designing and operating an intelligent network that reacts to changing power flows to ensure the optimal operation is the most economical option than fortifying the network with heavier cables. This work aims to build a model of a 13 bus medium voltage distribution network with high penetration of distributed energy resources and use it to analyze network conditions. The MATLAB Simulink software is used to model and evaluate the network. The outcomes suggest the model is promising and valid even when renewable generation is at low levels. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Personal high performance computer (PHPC) requires lower cost and high performance. The Teraflops PHPC systems with special accelerator units like GPGPU have been presented, but they have difficulties in programming, compatibility and applicability. In this paper, we present HPPPHPC, a hybrid architecture of heterogeneous processors connected by non-coherent off-chip system bus. The performance of HPP-PHPC is ensured by special processors integrated with vector units and high-efficiency interconnection between heterogeneous processors. And by the adoption of general processors and features like global physical address space and synchroniz ation semantics in hardware, HPP-PHPC is more compatible and convenient for massage passing and PGAS programming model. Also it is more applicable to most applications, including those with many execution branches. Initial results obtained from our prototype system have proved our design.

Service-Oriented Architectures (SOAs) enable businesses to flexibly address their current and future needs in an agile manner. This is achieved by organizing their software assets as interoperable services, which can be flexibly, cost-effectively and timely combined to form business processes according to business requirements. A SOA approach however can also benefit Virtual Organizations (VOs), by enabling participant companies to increase their responsiveness and adaptability with regards to addressing a collaborative business opportunity. Value can also be added to the operations of such a VO with the use of Web2.0 concepts, as well as intelligent Agents to automate the processes of finding collaborating partners and negotiating the creation of VOs, based on user-defined business rules. This paper discusses the combination of concepts and their potential benefits for Virtual Organizations, based on the ongoing work of a European Union co-funded Information Society Technologies (IST) project. Although at the time of writing of this paper the practical benefits of this approach are still in the evaluation phase, this paper discusses the main ideas and the expected contributions of such an approach.
