Procure Data Centre (PDC) is a coming forth patient data-centric framework of data interchange, large scale data centric applications. In which the data is been outsourced to be stored to general IT providers, such as cloud providers and how to assure their private data while being stored in the cloud servers. To secure the information govern over entree to their own file, it is a hopeful metho...

Corresponding Author: Toan Phan Thanh Hanoi National University of Education, Ha Noi, Vietnam Email: [email protected] Abstract: Although workflow scheduling problem has been discussed by many researchers, a few efficient solutions have been introduced for Cloud computing. In this article, we present LPSO, a novel algorithm for workflow scheduling. Based on the Particle Swarm Optimization meth...

Abstract— Most of the load balancing works in Cloud computing is carried out under homogenous resources. But today’s requirement has been diversified with the ever increasing heterogeneity of resources in the cloud resources. Our endeavour in this paper is to study the effect of Round robin technique with dynamic approach by varying the vital parameters of host bandwidth, cloudlet long length, ...

In this study, we propose an optimal cluster expansion-based intrusion-tolerant system (ITS) that can maintain quality of service (QoS) under a massive denial of service (DoS) attack. Our proposed scheme conserves resources while maintaining good QoS by optimally increasing and decreasing cluster size. To evaluate the performance of the proposed scheme, we use a CloudSim simulator and compare o...

Providing resource for virtual services in cloud computing which requires saving the resource and minimizing the amount of energy consumption is critical. In this study, we propose the resource model and linear programming formulation for multi-dimensional resource allocation problem. Based on the simulated annealing algorithm, RASA algorithms were designed to solve and evaluate through Cloudsi...

VM Migration for Autonomic Fault Tolerance provides the continuous availability for applications in the event of virtual machine failures along with the benefits of improved performance and manageability. Multipath correlation coefficient approach for VM migration has been proposed, which takes into account the overutilization of CPU without performance degradation based on work variability. Th...

Cloud Computing refers to the use of computing, platform, software, as a service. It’s a form of utility computing where the customer need not own the necessary infrastructure and pay for only what they use. Computing resources are delivered as virtual machines. In such a scenario, task scheduling algorithms play an important role where the aim is to schedule the tasks effectively so as to redu...

This paper proposes the creation of a trust model to ensure the reliable files exchange between the users of a private cloud. To validate the proposed model, a simulation environment with the tool CloudSim was used. Its use to run the simulations of the adopted scenarios allowed us to calculate the nodes (virtual machines) trust table and select those considered more reliable; identify that the...

Growing demand of computational power brings increasing scale and complexity of cloud datacenters. However, such increase also generates growing energy consumption and related cost incurred for cooling and maintenance. With concerns of cost and energy saving by both industry and academy, the reduction of energy consumption of cloud datacenters becomes a hotspot issue. Recently, virtual-machine-...
