The data replica management scheme is a critical component of cloud storage system. In order to enhance its scalability and reliability at the same time improve system response time, the multiple data replica scheme is adopted. When a cloud user issues an access request, a suitable replica should be selected to respond to it in order to shorten user access time and promote system load balance. ...

In cloud computing environment, there are a large number of users which lead to huge amount of tasks to be processed by system. In order to make the system complete the service requests efficiently, how to schedule the tasks becomes the focus of cloud computing Research. A task scheduling algorithm based on PSO and ACO for cloud computing is presented in this paper. First, the algorithm uses pa...

Nowadays, power consumption of data centers has huge impacts on environments. Researchers are seeking to find effective solutions to make data centers reduce power consumption while keep the desired quality of service or service level objectives. Virtual Machine (VM) technology has been widely applied in data center environments due to its seminal features, including reliability, flexibility, a...

The cloud computing paradigm provides a shared pool of resources and services with different models delivered to the customers through the Internet via an on-demand dynamically-scalable form charged using a pay-per-use model. The main problem we tackle in this paper is to optimize the resource provisioning task by shortening the completion time for the customers’ tasks while minimizing the asso...

Cloud computing is outsourcing of computing resources over the Internet where we can be connected to remote locations and can use the services over the Internet at another location to store our important information. The cloud service requirements provide access to advanced software applications. In cloud computing, the network of remote servers is used to process data. Workflow scheduling is o...

This paper proposes a novel approach for the implementation of simulation scenarios, providing a client entity for cloud computing systems. The client entity allows the creation of scenarios in which the client behavior has an influence on the simulation, making the results more realistic. The proposed client entity is based on several characteristics that affect the performance of a cloud comp...

Mobile Cloud Computing is a fast developing technology today that faces the dominant problem of load imbalance due to the high demand of mobile applications. There are lots of techniques available to solve the problem but the load balancing performance can be improved by using more optimized solution. This paper proposes a load balancing scheme based on Genetic Algorithm (GA). The algorithm adv...

In Cloud computing most of the energy efficient techniques give more attention to energy consumption in task resources such as CPU and memory of the physical machines in cloud. The network bandwidth is used to connect users to the cloud were paid less attention, the cloud network transmission and switching components also consumes significant percentage of total energy consumption. In the propo...

As one of the Vs defining Big Data, data velocity brings many new challenges to traditional data processing approaches. The adoption of cloud environments in complex event processing (CEP) systems is a recent architectural style that aims to overcome these challenges. Validating cloud-based CEP systems at the required Big Data scale, however, is often a laborious, error-prone, and expensive tas...
