Cloud-based services are growing more rapidly than ever, and so does the management challenge on their providers’ side. datacenter networks built with nodes of huge processing power, connected by high bandwidth capacities to carry interior traffic requirements. However, such cloud still have limits that imposed not necessarily physical components, but schemes resource being deployed. Traditiona...

A cloud data center is established to meet the storage demand due rate of growth data. The inefficient use resources causes an enormous amount power consumption in centers. In this paper, a fuzzy soft set-based virtual machine (FSS_VM) consolidation algorithm proposed address problem. uses four thresholds detect overloaded hosts and applies set approach select appropriate VM for migration. It c...

Cloud has proved to be a suitable choice for providing computing and storage resources especially for small and medium sized businesses in recent years. The “pay per usage” cost model, on demand computing, large scale storage resource with easy access, and freeing users from managing and maintaining resources are among the important factors that have made cloud an attractive choice for such ser...

Networks connecting distributed cloud services through multiple data centers are called cloud networks. These types of networks play a crucial role in cloud computing and a holistic performance evaluation is essential before planning a converged network-cloud environment. We analyze a specific case where some resources can be centralized in one datacenter or distributed among multiple data cent...

As underlying infrastructure of cloud computing platform, datacenter is seriously underutilized, however, its operating costs is high. In this paper, we implement virtual machines placement algorithm in CloudSim using constraint programming approach. We first formulate the problem of virtual machines placement in virtualized datacenters as a variant of multi-dimensions bin packing problem, and ...

Distributed Denial of Service (DDoS) attack launched in Cloud computing environment resulted in loss of sensitive information, Data corruption and even rarely lead to service shutdown. Entropy based DDoS mitigation approach analyzes the heuristic data and acts dynamically according to the traffic behavior to effectively segregate the characteristics of incoming traffic. Heuristic data helps in ...

The rising scales of FPGA deployments, especially in cloud environments scaling Accelerationas-a-Service, or for datacenter-wide workload acceleration, have created an urgent need for a unified and simple software interface to discover, access, and manage reconfigurable resources. Current system design methodologies either abstract FPGA access and resource management to provide a domain-specifi...

This paper takes a tour of Virtual Machine Migration systems across physical servers in datacenter which includes it’s architecture, basic working, migration strategies, design issues and goals. Despite of various on-going research for more than two decade in this field, variations in migrations procedures, context, environment and needs is still a major challenge faced by it. Keywords— Virtual...
