The huge energy consumption of datacenters providing cloud services over the Internet has motivated different studies regarding cost savings in datacenters. Since energy expenditure is a predominant part of the total operational expenditures for datacenter operators, energy aware policies for minimizing datacenters' energy consumption try to minimize energy costs while guaranteeing a certain Qu...

T he cloud computing paradigm has grown in popularity in industry and academia in recent years. Cloud computing aggregates several related technologies, such as virtualization, dynamic application scaling, datacenter management, and resource provisioning to provide an on-demand and elastic hosting environment for its users. While data management and storage are challenges, resource management i...

Trust and security have prevented businesses from fully accepting cloud platforms. To protect clouds, providers must first secure virtualized datacenter resources, uphold user privacy, and preserve data integrity. It is suggested using a trust-overlay network over multiple data centers to implement a reputation system for establishing trust between service providers and data owners. Data colori...

Disaster recovery planning and securing business processes against outtakes have been essential parts of running a company for decades. As IT systems became more important, and especially since more and more revenue is generated over the Internet, securing the IT systems that support the business processes against outages is essential. Using fully operational standby sites with periodically upd...

The emerging technology in the area of Information technology is Cloud Computing. Cloud Computing is the term associated with the virtualization, networking, software and services offered by web. The elements involved in cloud computing are clients, datacenter and distributed server. One of the main problems in cloud computing is load balancing. Balancing the load means to distribute the worklo...

To attain the desired reliability and energy efficiency of a cloud data center, trade-offs should be carried out between system performance and power consumption. Although the deployment of energy-efficient hardware is a crucial step, getting rid of underutilized servers is a far more effective approach. Achieving this in a cloud data center would require monitoring resource utilization as well...

This paper presents the performance evaluation of Quick UDP Internet Connections (QUIC), SCTP, TCP and TCP-Reno within Cloud and Cloudlet services. We first present the transport protocols and a comparison between Cloud and Cloudlet. Secondly, we assess the performance of QUIC compared to SPDY and TCP in terms of transport time decrease. Then, we present a simulation setting for energy aware us...

Due to popularity of Cloud computing environment, the cloud computing users are increasing day by day and that has become one of the important challenge for the cloud providers in terms of load balancing. Load balancing distributes the traffic evenly over multiple paths. In this research work, we have proposed the Dynamic Improved PSO Load balancing algorithm and implement it over CloudSim tool...

While the innovation and technology is modernizing the industry at rapid pace, the electrical power system is lagging behind the race and is being maintained in the same way for decades. Although the smart grid has ensured demand-response, reduction in transmission and distribution losses, and minimized theft, the inherent characteristic of enormous data generation has become a biggest concern....

Datacenter is usually shared among different applications and tenants as cloud service infrastructure. Traditional network allocation reserves the bandwidth but the traffic behavior is unpredictable. InfiniBand (IB) is more widely applied in the construction of datacenter cluster and attracts more interest from the academic field as well. In this paper, we first propose an IB bandwidth allocati...
