Cloud computing and big data: Technologies and applications

Dynamic resource provisioning is a challenging technique to meet the service level agreement (SLA) requirements of multi-tier applications in virtualization-based cloud computing. Prior efforts have addressed this challenge based on either a cost-oblivious approach or a cost-aware approach. However, both approaches may suffer frequent SLA violations under flash crowd conditions. Because they ignore the benefit gained that a multi-tier application continuously guarantees the SLA in the new configuration. In this paper, we propose a benefit-aware approach with feedback control theory to solve this problem. Experimental results based on live workload traces show that our approach can reduce resource provisioning cost by as much as 30% compared with a costoblivious approach, and can effectively reduce SLA violations compared with a cost-aware approach.

Execution of workflow application in cloud computing is widely applied, it is to apply heterogeneous resource in cloud for meeting the demand for large computational requirements. To maximize the efficiency of cloud computing, we have to effectively solve resources arrangement problem of workflow application in cloud computing, namely efficient task scheduling is needed. Cloud task scheduling problem is an NP-hard problem; therefore, a modified particle swarm optimization (PSO) is used to solve the task scheduling problem in the cloud, the grid task scheduling problems including how to distribute tasks to cloud resource and how to place a priority of tasks. In this study, two types of PSO are applied to solve these two issues, discrete particle swarm optimization is used to solve problem of distribution tasks in the cloud and a modified conventional PSO, named global topology controlling PSO (GTCPSO), is used in task priority assignments. In order to increase PSO searching efficiency, curve controlling is used to adjust the usage of global topology communication between particles so as to control search behavior of particle swarm. Thus, the swarm can perform global search at the initial stage, and then does fully local search at the last stage. The experiment results indicate that the curve controlling of topology communication between particles based on a designed global topology rate can efficiently solve the task scheduling problem and enhance performance of cloud computing.

Cloud computing is a combination of computer technology and internet-based development. Cloud computing uses the term "cloud", or cloud, to describe the internet, which is often depicted on computer network diagrams. Cloud computing capacity is an information technology service that can be accessed via the internet without knowing the infrastructure behind it. This opens up the possibility of accessing and using technology more efficiently and flexibly. The development of information technology, especially cloud computing, has had a significant impact in various fields, including education. Cloud computing changes the way information technology is distributed and accessed, providing opportunities for educational institutions to access data and educational resources more efficiently and flexibly. It also helps educational institutions to focus more on core educational processes without having to manage technology infrastructure directly. Teaching about cloud computing is becoming increasingly important. Because through an introduction to the basic concepts, types, benefits and practical applications of cloud computing, students can understand the importance of this technology in the modern world. Thus, teaching and training measures such as those described in this study are expected to help increase the understanding and application of cloud computing among students, preparing them for the challenges and opportunities in the ever-evolving digital era.

Streaming media is widely adopted by thousands of applications in cloud computing, how to effectively protect streaming media contents is a new challenge. In this paper, we propose an efficient online digital rights management (DRM) scheme supporting dynamic license in cloud computing. The content provider encrypts media content and outsources the encrypted content to cloud storage, while the user acquires dynamic license from the license server and consumes the streaming media content from the cloud storage. Further, we present a secure key distribution protocol based on proxy re-encryption, which protects the confidentiality of content encryption key, and reduces the work of key management in the cloud, and also supports domain key to realize user domain management. In addition, we develop a prototype system with Google cloud storage APIs based on the proposed scheme, and the implementation and comparison results show that the proposed scheme satisfies the requirements of online media content protection in cloud computing.

Cost efficiency is an often mentioned strength of cloud computing. In times of decreasing educational budgets virtual labs provided by cloud computing might be therefore an int eresting option for higher education organizations or IT training facilit ies. An analysed use case of a web technology lecture and a corresponding practical course of a co mputer science study programme shows that is not possible to answer the question in general whether cloud computing approaches are economical or not. The general implication of this finding for h igher education is, that the application of cloud computing can be only answered fro m a course specific point of view. This contribution shows why. But also how universities, colleges or other IT training facilit ies can make pro found and course specific decisions for or against cloud based virtual labs from an economic point of view. The presented approach is inspired by Weinmans mathematical proof of the inevitability of cloud co mputing. The key idea is to co mpare peak to average usage of virtual labs and relate this ratio to costs of classical dedicated labs . The rat io of peak and average usage indicates whether a use case (fro m a pure economical point of view) is cloud compatible or not. This contribution derives also some findings when cloud computing in h igher education has economical advantages or disadvantages. Regarding the analysed use case it turned out that virtual labs are able to provide a more than 25 times cost advantage compared to classical dedicated approaches . Virtual labs can be applied frict ionless to classical as well as distance study programmes and virtual labs provide a convenient infrastructure for project as well as problem based learning in co mputer science. Nevertheless provider of virtual labs should always consider usage and resulting cost characteristics. This article shows how to do this.

In the past, data processing was completed on a computer or a server. This is because the resources available at that time were limited. However, with the progress of technology, it is possible to use multiple computers and servers to process large amounts of data. This is where cloud computing comes into play. Cloud computing allows users to access data from anywhere at any time using an Internet connection. It also reduces the cost of enterprises because they do not have to buy additional hardware or software for each user. Aiming at the problems of single scale of traditional computer data processing and poor degree of adaptive parallel computing, this paper proposes a multi-source information accelerated data processing method of cloud computing technology, analyzes the application of cloud computing technology in computer data processing, and adopts the dynamic optimization technology of cloud computing speed to build a dynamic adjustment model of multi-source information data flow application of cloud computing, so as to reduce the energy cost of cloud computing, Combined with the experience of data processing users, the model can support multi-user computing entity sharing in the cloud to improve the running efficiency of data flow applications and reduce the energy cost of computer data processing. This article first outlines the basic meaning of cloud computing technology, starting with providing conditions for data transmission and sharing, and highlighting the application value of cloud computing technology. It analyzes the trend of cloud computing technology, and combines the modeling of cloud computing technology in computer data processing to propose application countermeasures for cloud computing technology in computer data processing.

Advances in cloud computing have aroused many researchers’ interest in privacy-preserving feature extraction over outsourced multimedia data, especially private image data. Since block truncation coding (BTC) is known as a simple and efficient technology for image compression, this paper focuses on privacy-preserving feature extraction in BTC compressed domain. We propose a privacy-preserving computation of BTC feature extraction over massive encrypted images (also called PPBTC). First, all images are uploaded to the cloud after encryption. The privacy-preserving image encryption process consists of block permutation, pixel diffusion, and a bit-plane random shift. BTC features remain unchanged after encryption and the cloud server can directly extract BTC features from the encrypted images. Some analyses and experimental results demonstrate that the proposed privacy-preserving feature extraction scheme for BTC-compressed images is efficient and secure, and it can be applied to secure image computation applications in cloud computing.

The cloud security assessment model has been validated through examples, and the results show that the proposed model can make quantitative assessment on secure cloud platform effectively, with much more efficiency.

Free to read on publisher's website Utilizing dynamic resource allocation for load balancing is considered as an important optimization process in cloud computing. In order to achieve maximum resource efficiency and scalability in a speedy manner this process is concerned with multiple objectives for an effective distribution of loads among virtual machines. In this realm,exploring new algorithms, as well as development of novel algorithms, is highly desired for technological advancement and continued progress in resource allocation application in cloud computing. Accordingly, this paper explores the application of two relatively new optimization algorithms and further proposes a hybrid algorithm for load balancing which can contribute well in maximizing the throughput of the cloud provider's network. The proposed algorithm is a hybrid of teaching-learning-based optimization algorithm (TLBO) and grey wolves optimization algorithm (GW). The hybrid algorithm performs more efficiently than utilizing every single one of these algorithms. Furthermore, it well balances the priorities and effectively considers load balancing based on time, cost, and avoidance of local optimum traps, which consequently leads to minimal amount of waiting time. To evaluate the effectiveness of the proposed algorithm, a comparison with the TLBO and GW algorithms is conducted and the experimental results are presented.

Cloud computing has created a dramatic change in the banking sector. It is now possible to do cost-efficient, scalable, and high-performance online transactions using the applications of cloud computing. In addition to improving data storage, processing speed, and security, cloud computing reduces costs used in infrastructure. High latency, security risks, and compliance issues mar the traditional banking systems. These limitations made traditional banking inefficacious for recent financial applications such as High-Frequency Trading. This paper proposes a secure and efficient cloud-based high frequency trading (HFT) system based on Lattice-Based Post-quantum Cryptography (LBPQC) and Partially Homomorphic Encryption (PHE) for the provision of more secure transactions. The system minimizes both latency and computational expenses, thereby facilitating real-time executions while improving trade precision by 15% and reducing security breach chances by 20%. AI-driven compliance automation and anomaly detection are also complemented into the model for regulatory compliance. Much higher data protection as well as efficiency in the trade, and threat detection are possible with the proposal that will ensure effective and secure banking infrastructure for any cloud financial activity.

This article is Part 3 of a series of studies on new generation of electronic contact challenges and component interconnects technology for high-end computer products. These products include server and data storage for cloud computing applications at the data center as well as core routers for service providers, edge and branch routers for enterprise networking companies, and small switch and wireless router for commercial and small and home office. All these cloud computing products require high data speed in terabytes per second and high signal integrity for the massive mobile users and IoT application whenever and wherever they wish to connect. To achieve such mobility and signal integrity the major focus is the electrical interconnections between the CPU/GPU and component in the system. Due to the large number of edgecard connections such as DIMM, PCIe, etc. in modern computer systems and due to their relatively low reliability, in previous Part 2 of the study a test vehicle with daisy chain was used to assess the contact interconnect failure related to factors such as soldering flux residue, plating quality, contact interface cleaning and doubt insertion, and particulate control and management. As concluded in Part 2, the heavy flux residue and vibration pre-conditioning have medium effect on contact failure, however contact interface cleaning and particulate control show no significant contribution and not able to eliminate the last thousands DPPM of DIMM contact failure. The purpose of current Part 3 of the study is to look into a new generation of dual-contact interconnect methodology and assess component level contact configuration and interconnect reliability. First, the contact pin configuration and plating morphology such as homogeneity and thickness are carefully examined to ensure contact integrity between DDR4 connect and DIMM module can be achieved. Then normal force of dual-pin and separated single-pin from the whole were measured to benchmark to existing conventional singlecontacts. Furthermore the JEDEC Raptor test vehicle was adapted to assess contact impedance and four signal integrity tests, RL (return loss), IL (insertion loss), NEXT (near-end cross talk), and FEXT (far-end cross talk) to ensure signal integrity requirements are fulfilled. Finally, board level reliability test is proposed for Raptor test board and trial run on real product. The overall goal of Part 3 of the study is to ensure a smooth migration from conventional single-contact to a new interconnect mechanism with robust board and system reliability for high signal integrity requirement in cloud computing and IoT application.
