  • Access Control Mechanisms for Outsourced Data in Public Cloud Using Polynomial Interpolation and Multilinear Map   Order a copy of this article
    by Purushothama B R 
    Abstract: Cloud computing is a computing paradigm in which the resources of the computing infrastructure are provided as services over the Internet. This paradigm poses new data security and access control challenges when the users outsource their sensitive data on to cloud storage. The adoption of the cloud storage providers for the data hosting is attracting the organizations or data owners to provide a cost effective availability of data for customers access. Often the cloud servers are honest-but-curious. The outsourced data should be protected from unauthorized access. Data should be encrypted to maintain the confidentiality of the data. Encrypting all the data to be outsourced with a single key known to the data owner requires the data owner to participate during the data access by the users. Multi-key encryption strategies require the users to manage multiple keys. The objective of our work is to enforce the access privileges to outsourced data reducing the key management at the users and to remove the need of participation of data owner during data accesses. In this work, we propose three access control schemes. 1) Access control scheme based on the principle of polynomial interpolation. 2) Access control scheme using Multilinear map. 3) Dynamic access control scheme using Multilinear map. The security of the schemes using Multilinear map is based on the Multilinear Diffie-Hellman assumption. In our schemes, the key generated to encrypt the data is regulated by the access authorizations holding on the data. In all the three proposed schemes, the authorized user needs to store only one key irrespective of the number of data items to which he has authorized access and do not require the data owner's participation except in grant and revoke operations.

    by Mahantesh Birje, Praveen Challagidad, R. H. Goudar 
    Abstract: Cloud computing delivers IT related capabilities as a service through internet to multiple customers and these services are charged based on consumption. Many cloud computing providers such as Google, Microsoft, Yahoo, IBM and Amazon are moving towards adoption of cloud technology leading to considerable escalation in the usage of various cloud services. Amazon is the pioneer in this field because of its more number of architectural features compared to others. To meet the need of cloud service providers and customers various open source tools and commercial tools are being developed. Though many more developments have been taken place in cloud computing area, challenges such as security, interoperability, resource scheduling, virtualization etc. are yet to be fine tuned. This paper reviews cloud computing paradigm in terms of its historical evolution, concepts, technology, tools and various challenges. SLR (Systematic Literature Review) of seventy selected papers, published from 2006 to 2015 was conducted to properly understand the nuances of the cloud computing paradigm. Since security is the major challenge in cloud computing, it is discussed separately in detail. It helps researchers who would like to begin their research career in cloud computing area.

  • Transaction Management with Tree-Based Consistency in Cloud Databases   Order a copy of this article
    by Susan V. Vrbsky, Ashfakul Islam 
    Abstract: The maintenance of the ACID properties of Atomicity, Consistency, Isolation and Durability has been one of the main challenges to the implementation of transactional databases in the cloud. The main cloud computing features of scalability, availability and reliability are typically achieved by sacrificing consistency. While different forms of consistency have been introduced, these weaker consistent states do not address the needs of many database applications. In this paper we implement a transaction management system using our TBC (Tree-Based Consistency) approach. TBC is serializable and guarantees the ACID properties. Our experimental results illustrate that TBC has better performance than other approaches, such as the quorum approach, regardless of the arrival rate, read-write ratio, or database size. The Tree-Based Consistency approach is shown to be a viable solution for ACID transactional database management in a cloud.

  • A Framework for Integrating Wireless Sensors and Cloud Computing   Order a copy of this article
    by Mohammad Jassas, Qusay Mahmoud 
    Abstract: Wireless sensors generate a large volume of data that require a highly scalable framework that enables storage, processing, and analysis. Cloud computing technology can provide unlimited storage in addition to a flexible processing infrastructure, allowing for the management and analysis of vast amounts of sensor data. This paper presents a framework for integrating wireless sensors and cloud computing. This framework can provide scalability and high availability for applications that use wireless sensors. Moreover, this cloud-based framework is designed to immediately make decisions based on real-time sensor and historical data, and a list of sensor and user policies are defined by the system administrator. In order to evaluate the framework performance after applying scalability and availability techniques, a load testing environment was built in the cloud to simulate a large number of virtual users. This environment was created in order to examine the quality of the services as provided by Windows Azure. The results have shown that the use of scalability techniques can significantly increase availability and performance.

  • Design and Evaluation of a Fuzzy Cloud Controller   Order a copy of this article
    by Bill Karakostas, Dimitris Kardaras 
    Abstract: The management of Cloud deployments is still largely the responsibility of system administrators. Introducing autonomy in Cloud management would entail, amongst other things, the ability for automated Cloud manager systems to scale up or down the number of deployed virtual machines, and/or deploy machines of different types to meet performance and other SLAs. However, the workload of Cloud deployments can exhibit high variability over short time periods. This creates the necessity of introducing autonomic behaviour in the resource management function of the Cloud deployment that makes decisions in real time so to optimise cost and/or performance. In this paper, we employ fuzzy logic to design a cloud controller whose scaling policies emulate the reasoning of human Cloud operators, and take into account the current system load and the system load rate of change. The fuzzy controller's performance is compared and evaluated against Amazons AWS auto-scaling policies. Results indicate the ability of the proposed fuzzy controller to adapt better to changing workloads by provisioning virtual machines appropriately to match the rate of system load change. Additionally, fuzzy rules are more intuitive than auto-scaling policies and thus easier to understand and modify by human users.

  • Competitive infrastructure up-gradation in federated cloud   Order a copy of this article
    by Subhasis Thakur 
    Abstract: A federated cloud is a collaboration among a set of Cloud Providers(CP) and it acts as a connected network. In a federated cloud, the virtual network requests are mapped to the resources belonging to multiple CPs. Despite being a collaboration, an individual CP gets better utility if the usage of its own part of the network increases. In this paper, we study the problem of upgrading the federated cloud.We only consider the connectivity improvement among the CPs. The usage of the part of the network owned by a CP depends on its connectivity with the rest of the network. Better the connectivity better the usage. A CP will be interested in improving the network in such a way that such improvement makes its part of the network more accessible from other clouds. At the same time, being competitive, it will avoid any improvement that facilitates better accessibility among other CPs. In this paper we study how the CPs decide on such improvement by themselves. We model this problem as a non-cooperative game. We study the existence of the pure Nash equilibrium and study the complexity to find the pure Nash equilibrium. Further, using price of anarchy, we demonstrate the effect of the selfish choices made by the CPs on the overall performance of the network.
    Keywords: Federated cloud, Nash equilibrium, connectivity augmentation

  • De-centralized Dynamic Task Scheduling Using Hill Climbing Algorithm in Cloud Computing Environments   Order a copy of this article
    by Mona Mohammadi, Amir Masoud Rahmani 
    Abstract: There are many tasks in cloud computing that should be executed by available resources to acquire high performance, reduce task completion time, increase utilization of resources and etc. Since task scheduling problem in cloud computing is an NP-Hard problem, designing an efficient scheduling strategy to achieve the intentions listed above is challenging. Task scheduling is the process of allocating tasks to available resources such that performance metrics are improved. This paper proposes a dynamic scheduling algorithm that uses hill climbing algorithm. It tries to minimize completion time of tasks while maximizing throughput and utilization of resources. This algorithm allocates independent tasks to available resources to achieve load balance. The simulation results show that the algorithm can achieve load balance and reduces completion time of tasks.

  • Fuzzy Logic Based VM Selection Strategy for Cloud Environment   Order a copy of this article
    by Mohammad Alaul Haque Monil, M. Rashedur Rahman 
    Abstract: Server consolidation allows data centers to increase resource utilization and reduce electric power consumption by gathering multiple virtual machines into physical servers. When a server is found to be overloaded or underloaded, a list of Virtual Machines (VMs) must be selected to migrate. VM selection is an important task as the energy consumption depends on it. A number of VM selection strategies have been proposed in the literature. Each VM selection method has its distinguished characteristics. For example, one VM selection method has low energy consumption but high SLA violation and vice versa. As different VM migration approaches offer distinct advantages, fuzzy logic has been explored and applied in this research to innovate a new VM selection method which will provide a balanced and better result in all Quality of Service (QoS) measures. With this goal, we designed the Fuzzy VM selection using three different metrics. We have devised the membership function and inference rule based on the data provided by real Cloud workload data, e.g., PanetLab. We implement our novel Fuzzy VM selection method in CloudSim toolkit and compare the performance with the existing methods. Simulation results demonstrate that Fuzzy VM selection method provides a balanced performance by trading off power and other QoS parameters compared to other VM selection strategies found in literature.

  • Mathematical Model of Security Approaches on Cloud Computing   Order a copy of this article
    by Zico Mutum 
    Abstract: Over the years, there is a significant advance in cloud computing technology. It has grown from being a promising business concept to one of the fast growing sector of the information technology organizations. However, customers are still reluctant to deploy their business in the cloud. Security is one of the key factor which hampers the growth of cloud computing. The exponential growth of the Internet users has also lead to a significant growth of threats. Mathematical modeling plays as an important tool in analyzing and mitigating possible threats or attacks on cloud computing. This paper focuses on mathematical models on security issues arising from the usage of cloud services. We propose a model for detecting possible threats on cloud system using probability process.

  • A Scalable Resource Provisioning Scheme for the Cloud using Peer to Peer Resource Discovery and Multi Attribute Utility Theory   Order a copy of this article
    by Rayhanur Rahman, Kazi Sakib 
    Abstract: Serving large number of users without compromising service availability and performance is key to the success of the Cloud. A fundamental challenge in building such services is incorporating scalability and fail safe techniques for discovering and provisioning of resources. As Peer to Peer (P2P) architectures are invincible to these setbacks, the work proposes a P2P based resource discovery and provisioning method for the Cloud. It first addresses the multi attribute data publishing and the range querying inability of existing Distributed Hash Table (DHT) based P2P schemes and proposes an attribute hub based discovery of provisioning information. Focused on that, a decentralized resource provisioning model is proposed using Multi Attribute Utility Theory methods. The simulation shows that the proposed approach is 44:24%and 45:81% faster than the centralized and DHT based approaches respectively in case of multidimensional range querying. It also shows the lesser number of Service Level Objective (SLO) violations and migrations which are about 24:11% and 33:43% respectively.

  • Cloud Computing Resource Allocation Taxonomies   Order a copy of this article
    by Fabio Lopez-Pires, Benjamín Barán 
    Abstract: Cloud computing datacenters dynamically provide millions of virtual machines in actual cloud computing markets. Several challenging problems have to be addressed towards an efficient resource management of these cloud computing infrastructures. In the context of resource allocation, Virtual Machine Placement (VMP) is one of the most studied problems with several possible formulations and a large number of existing optimization criteria, considering solutions with high economical and ecological impact. Based on systematic reviews of the VMP literature, this work presents novel taxonomies in order to: (1) understand different possible environments where a VMP problem could be studied from both provider and broker perspectives in different deployment architectures, (2) identify existing approaches for the formulation and resolution of the VMP as an optimization problem and (3) present a detailed view of the VMP problem, identifying research opportunities to further advance in this area.

    by Abdullah Qasem, Qusay Mahmoud 
    Abstract: Designing, implementing and executing algorithms have become a relevant and important element in various fields. Public users and data researchers are interested in analyzing and interpreting data with shorter execution time and higher performance. Cloud computing is an environment that provides scalable and high-end virtual resources to achieve high quality services. This paper presents the design, implementation and evaluation of a framework for provisioning algorithms as a service in the cloud. This framework introduces solutions to help clients overcome different concerns and difficulties, such as looking for an appropriate algorithm, understanding algorithm source code, installing and configuring specific libraries, and achieving high algorithmic performance. The framework provides clients the possibility to discover available algorithms and/or deploy new algorithms over multiple scalable platforms. It also allows clients to analyze data, compare results, and measure algorithms performance. A prototype implementation of the framework has been developed to demonstrate the feasibility of the solution. Evaluating results demonstrate that providing multiple scalability models and high-end web servers will improve algorithm performance and achieve availability and reliability using the framework.

    by Frederic Nzanywayingoma 
    Abstract: we are living in the data world where a high volume of data is changing the way things used to be in traditional IT industry. Big Data is being generated everywhere around us at all times by cameras, mobile devices, sensors, and software logs with large amount of data in units of hundreds of terabytes to petabytes. Therefore, to analyze these massive data, new skills, intensive applications and storage clusters are needed. Apache Hadoop is one of the most recently popular tools developed for big data processing. It has been deployed by many giant companies to stream large files in big datasets. The main purpose in this paper is to analyze different scheduling algorithms that can help to achieve better performance, efficiency and reliability of Hadoop YARN environment. We describe some task schedulers which consider different levels of Hadoop such as FIFO (First In First Out) scheduler, fair scheduler, delay scheduler, deadline constraint scheduler, dynamic priority scheduling, capacity scheduler, and we analyze the performance of these widely used Hadoop task schedulers based on the following elements: makespan; turnaround time; and throughput. A reliable scheduling algorithm is suggested which can work efficiently in Hadoop environments. To conclude this paper, the experimental results were given.
