In cloud computing, a cloud is a managed pool of resources which provide on-demand services or computational resources to the remote users over a network. The resources are provided to users in the form of virtual machines and are possibly distributed and heterogeneous, running on the cloud environment over Internet. Energyaware Scheduling algorithm and Energy-aware Live Migration algorithm red...

Technology providers heavily exploit the usage of edge‐cloud data centers (ECDCs) to meet user demand while ECDCs are large energy consumers. Concerning decrease expenditure ECDCs, task placement is one most prominent solutions for effective allocation and consolidation such tasks onto physical machine (PM). Such must also consider additional optimizations beyond power include other objectives,...

Migration of Virtual Machine (VM) is a critical challenge in cloud computing. The process to move VMs or applications from one Physical Machine (PM) to another is known as VM migration. In VM migration several issues should be considered. One of the major issues in VM migration problem is selecting an appropriate PM as a destination for a migrating VM. To face this issue, several approaches are...

Cloud computing has innovated the IT industry in recent years, as it can delivery subscription-based services to users in the pay-as-you-go model. Meanwhile, multimedia cloud computing is emerging based on cloud computing to provide a variety of media services on the Internet. However, with the growing popularity of multimedia cloud computing, its large energy consumption cannot only contribute...

In Virtualized Data Center (VDC), a single Physical Machine (PM) is logically divided into one or more Virtual Machines (VMs) that share physical resources. Therefore, dynamically resource provisioning plays an important role in VDC. Moreover the resource provider would like to maximize resource utilization, which forms a large portion of their operational costs. To achieve this goal, several c...

In recent years, cloud computing providers have been working to provide highly available and scalable cloud services to keep themselves alive in the competitive market of various cloud services. The difficulty is that to provide such high quality services, they need to enlarge data centers (DCs), and consequently, to increase operating costs. Hence, leveraging cost-aware solutions to manage res...

Infrastructure as a Service cloud providers are increasingly relying on scalable and efficient Virtual Machines (VMs) placement as the main solution for reducing unnecessary costs and wastes of physical resources. However, the continuous growth of the size of cloud data centers poses scalability challenges to find optimal placement solutions. The use of heuristics and simplified server consolid...

The consolidation of data from different sources can be particularly vexing in the determination of the values of the fundamental physical constants. For example, the U.S. National Institute of Standards and Technology (NIST) recently reported “two major inconsistencies” in some measured values of the molar volume of silicon Vm(Si) and the silicon lattice spacing d220, leading to a recommended ...
