On this basis, depth study of the logistics and distri...

Security and performance are basic requirements for any system. They are considered the criteria for the measurement of any progress in a security system. Security is an indicator that affects the level of performance through the threats that influence the performance of parts of the cloud during the rendering of services. Both security and performance demonstrate the efficiency of cloud comput...

Cloud system is gaining the importance in public environment. But security is always a critical challenge while sharing the valuable information. In this work, a high level integrated security model is presented for managing large data on cloud system. In this work, a RSA integrated SHA method is presented to provide the secure file management in distributed cloud. The proposed authentication a...

Cloud computing provides reliable, customized and guaranteed dynamic computing environments for endusers, so that more and more people tend to adapt the cloud environment in their workplace. Cloud computing is becoming an increasingly popular enterprise model in which computing resources are made available on-demand to the user as needed. The unique concept of cloud computing creates new opport...

In this paper we propose the concept of an inverted cloud infrastructure. The traditional view of a cloud is turned upside down: instead of having services or infrastructure offered by a single provider, the same can be achieved by an aggregation of a multitude of mini providers. Even though the contribution of an individual mini provider in an inverted cloud can be limited, the combination wou...

We perform linear analysis of thermal instability in a contracting large cloud filled with warm H I gas and investigate the effect of metallicity and radiation flux. When the cloud reaches critical density n f , the cloud fragments into cool, dense condensations because of thermal instability. For a lower metallicity gas cloud, the value of n f is high. Collision between condensations will prod...

As cloud computing technologies continue to develop and evolve, cloud infrastructure has become heterogeneous and multi-tiered. A new demand in cloud computing is to provide cloud functionalities at the customer premise to support customer needs. This demand is addressed in this paper by providing virtual Customers Premise Equipment (vCPE) as a third tier of the SAVI Testbed, which is a platfor...

Cloud computing represents today’s most exciting computing archetype. It gives computing via internet. Cloud systems can be used to enable data sharing capabilities and this can provide abundant of benefits to the user. It is the most important trend in cloud technology for allows users to access data expediently. Privacy and security is the big challenge for stored data in cloud. Most existing...

This work aims to highlight the benefits of Cloud Automation for industrial adopters and some of the research challenges that must be addressed in this process. The focus is on the use of cloud computing for efficiently planning the motion of new robot manipulators designed for flexible manufacturing floors. In particular, different ways that a robot can interact with a computing cloud are cons...

Cloud computing is a highly scalable and cost-effective infrastructure for running HPC, enterprise and Web applications. However, the growing demand of Cloud infrastructure has drastically increased the energy consumption of data centers, which has become a critical issue. High energy consumption not only translates to high operational cost, which reduces the profit margin of Cloud providers, b...
