Optimal resource utilization for executing tasks within the cloud is one of the biggest challenges. In executing the task over a cloud, the resource provisioner is responsible for providing the resources to create virtual machines. To utilize the resources optimally, the resource provisioner has to take care of the process of allocating resources to Virtual Machine Manager (VMM). In this paper,...

The cloud pricing model leaves cloud consumers vulnerable to Economic Denial of Sustainability (EDoS) attacks. In this type of attacks, an adversary first identifies web resources with high levels of cloud resource consumption, and then uses a botnet of compromised hosts to make fraudulent requests to these costly web resources. The attacker’s goal is to disrupt the economical sustainability of...

Cloud computing has become one of the hottest topics in the IT world today. Its model of computing as a resource has changed the landscape of computing as we know it, and its promises of increased flexibility, greater reliability, massive scalability, and decreased costs have enchanted businesses and individuals alike. Cloud computing, as defined by NIST, is a model for enabling always-on, conv...

In order to provide the agricultural works with customized, visual, multi-perspective and multi-level active service, we conduct a research of digital agricultural information resources sharing plan based on cloud computing to integrate and publish the digital agricultural information resources efficiently and timely. Based on cloud computing and virtualization technology, we establish a cloud ...

Cloud computing offers a wide range of benefits including potential cost-savings by leasing resources from cloud service providers and improved user experience by Geodistributing applications [17]. Cloud service providers typically share the platform and cloud resources across multiple users for better utilization. They lease resources on-demand to users in three broad flavors, namely, Infrastr...

Contrary to many other approaches to security and privacy in the cloud, we are interested in the problem of hiding behavioral information of users consuming their cloud resources, e.g. CPU time or storage space, from the cloud provider. More precisely, we are looking for solutions that allow users to purchase a contingent of resources from a cloud provider and to anonymously consume their resou...

The computational world is becoming very large and complex. Cloud computing has emerged as a new paradigm of computing and also has gained attention from both academic and business community. Its utility-based usage model allows users to pay per use, similar to other public utility such as electricity, with relatively low investment on the end devices that access the cloud computing resources. ...

Cloud computing platforms such as Amazon EC2 provide customers with flexible, on demand resources at low cost. However, while existing offerings are useful for providing basic computation and storage resources, they fail to provide the security and network controls that many customers would like. In this work we argue that cloud computing has a great potential to change how enterprises run and ...

Cloud computing is an attractive computing model since it allows for resources to be provisioned according on a demand basis, i.e., cloud users can rent resources as they become necessary. This model motivated several academic and non-academic institutions to develop open-source cloud solutions. This paper presents and discusses the state-of-the of open-source solutions for cloud computing. The...

Cloud infrastructures needs to become more smarter and dynamic in managing resources, requiring new solutions and tools to cope with processes of configuration and reconfiguration, automatic scaling, elastic computing and healthiness control. This paper presents a Smart Cloud solution for automatically managing cloud infrastructures, and programming the monitoring aspects directly from the conf...
