Now all kinds of public cloud providers take computing and storage resources as the user’s main demand, making it difficult for users to deploy complex network in the public cloud. This paper proposes a virtual cloud platform with network as the core demand of the user, which can provide the user with the capacity of free network architecture as well as all kinds of virtual resources. The network is isolated by port groups of the virtual distributed switch and the data forwarding and access control between different network segments are implemented by virtual machines loading a soft-routing system. This paper also studies the management interface of network architecture and the uniform way to connect the remote desktop of virtual resources on the web, hoping to provide some new ideas for the Network as a Service model.

PurposeMajor public cloud providers, such as AWS, Azure or Google, offer seamless experiences for infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS). With the emergence of the public cloud's vast usage, administrators must be able to have a reliable method to provide the seamless experience that a public cloud offers on a smaller scale, such as a private cloud. When a smaller deployment or a private cloud is needed, OpenStack can meet the goals without increasing cost or sacrificing data control.Design/methodology/approachTo demonstrate these enablement goals of resiliency and elasticity in IaaS and PaaS, the authors design a private distributed system cloud platform using OpenStack and its core services of Nova, Swift, Cinder, Neutron, Keystone, Horizon and Glance on a five-node deployment.FindingsThrough the demonstration of dynamically adding an IaaS node, pushing the deployment to its physical and logical limits, and eventually crashing the deployment, this paper shows how the PackStack utility facilitates the provisioning of an elastic and resilient OpenStack-based IaaS platform that can be used in production if the deployment is kept within designated boundaries.Originality/valueThe authors adopt the multinode-capable PackStack utility in favor of an all-in-one OpenStack build for a true demonstration of resiliency, elasticity and scalability in a small-scale IaaS. An all-in-one deployment is generally used for proof-of-concept deployments and is not easily scaled in production across multiple nodes. The authors demonstrate that combining PackStack with the multi-node design is suitable for smaller-scale production IaaS and PaaS deployments.

Provisioning Virtual machines on demand is significant in elastic compute cloud for reliable service delivery. The importance and major difficulty lies in satisfying the conflicting objectives of satisfying contracted service level agreement while lowering used resource costs. In this paper, the authors propose a mathematical multi-tier framework for adaptive virtual resource allocation problem. The framework captures the performance of the virtualized cloud platform gracefully. The authors first use simulations to derive virtual resource allocation policies, and later use real benchmarking applications, to verify the effectiveness of this framework. Experimental results show that the model can be simply and effectively used to satisfy the response time requirement as well as lowering the cost of using the virtual machine resources.

Multimedia Content Protection

Cloud computing has emerged to influence multimedia content providers like Disney to render their multimedia services. When content providers use the public cloud, there are chances to have pirated copies further leading to a loss in revenues. At the same time, technological advancements regarding content recording and hosting made it easy to duplicate genuine multimedia objects. This problem has increased with increased usage of a cloud platform for rendering multimedia content to users across the globe. Therefore it is essential to have mechanisms to detect video copy, discover copyright infringement of multimedia content and protect the interests of genuine content providers. It is a challenging and computationally expensive problem to be addressed considering the exponential growth of multimedia content over the internet. In this paper, we surveyed multimedia-content protection mechanisms which throw light on different kinds of multimedia, multimedia content modification methods, and techniques to protect intellectual property from abuse and copyright infringement. It also focuses on challenges involved in protecting multimedia content and the research gaps in the area of cloud-based multimedia content protection.

Data deduplication is necessary for corporations to minimize the hidden charges linked with backing up their data using Public Cloud platform. Incapable data storage on its own can become improvident, and such problem are enlarging in the Public Cloud at other and scattered satisfied confirmed storage structure are creating multiple clone of single account for collating or other purposes. Deduplication is friendly in cost shrinking by lengthening the benefit of a precise volume of data. Miserably, data duplicity having several safety constraints, so more than one encoding is appropriate to validate the details. There is a system for dynamic Information-Locking and Encoding with Convergent Encoding. In this Information-Locking and Encoding with Convergent Encoding, the data is coded first and then the cipher text is encoded once more. Chunk volume is used for deduplication to diminish disk capacity. The same segments would still be encrypted in the same cipher message. The format of the key neither be abbreviated from encrypted chunk data by the hacker. The comprehension is also guarded from the cloud server. The center of attention of this document is to reducing disk storage and provides protection for online cloud deduplication.

The article is devoted to the modern Russian party system. In the first part of the article, the author shows the historical features of the parties formation in Russia and analyzes the reasons for the low turnout in the elections to the State Duma in 2016. According to the author the institutional reasons consist in the fact that the majority of modern political parties show less and less ability to produce new ideas, and the search for meanings is conducted on the basis of the existing, previously proposed sets of options. Parties reduce the topic of self-identification in party rhetoric, narrowing it down to “branded” ideas or focusing on the image of the leader. In addition, the author shows the decrease in the overall political activity of citizens after the 2011 elections, and points out that the legislation amendments led to the reduction of the election campaigns duration and changes in the voting system itself. The second part of the article is devoted to the study of the psychological aspects of the party system. The author presents the results of the investigation of images of the parties as well as the results of the population opinion polls, held by the centers of public opinion study. On the basis of this data, the author concludes that according to the public opinion the modern party system is ineffective, and the parties don’t have real political weight, which leads to the decrease of the interest in their activities and confidence in them. The author supposes that all this may be the consequence of the people’s fatigue from the same persons in politics, but at the same time the electorate’s desire to see new participants in political processes is formulated rather vaguely, since, according to the people, this might not bring any positive changes.
