Cloud computing has become one of the fastest growing fields in computer science. As the new computing service pattern of cloud computing develops rapidly, the security problem of cloud computing has become a hot research topic. Before the user passes important data or computing task to the cloud, the user of the cloud may want to verify the trusted status of the platform which actually carries...

Recently, cloud computing platforms, such as Microsoft Azure, are available to provide convenient infrastructures such that cloud applications could conduct cloud and data-intensive computing. To ensure high quality of cloud applications under development, developer testing (also referred to as unit testing) could be used. The behavior of a unit in a cloud application is dependent on the test i...

Unlike traditional high performance computing environment, such as supercomputers, the cloud computing is a collection of interconnected and virtualized computing resources that are managed to be one or more unified computing resources. The Cloud environment constitutes a heterogeneous and a highly dynamic environment. Failures on the data centers storage nodes are normal rather than exceptiona...

Scheduling of tasks in cloud environment is a key research area. Cloud computing environment provides virtualized resources to applications dynamically. These resources are costly and often impossible for users to own them privately. Users are charged on a pay-per-use basis for these resources on cloud environment. The idea of task scheduling in cloud environment is to optimize the execution ti...

Cloud manufacturing is a new paradigm which has been under study since 2010 and a vast body of research has been conducted on this topic. Among them, service composition problems are of utmost importance. However, most studies only focused on private clouds meaning the objective function is defined for just one component of the supply chain. This paper attempts to consider service composition p...

Cloud Computing is a talented model which based on cloud services and cloud providers. Cloud computing allows user to slightly store their data in server side. Cloud computing provides services which provides services on demand and anywhere. In data storage data security and privacy are the critical issues which provide data confidentiality and access control. Attribute based encryption is a pr...

The development of Future Internet and Cloud computing creates new challenges for simulation scientists in terms of enhancing the accessibility to distributed simulation and empowering the researchers from other disciplines. The article tests the operation of simulation communication environment using Cloud infrastructure. The results of the experiment within Amazon EC2 Cloud infrastructure sho...

Cloud Computing is a new trend emerging in IT environment with huge requirements of infrastructure and resources. Load Balancing is an important aspect of cloud computing environment. Efficient load balancing scheme ensures efficient resource utilization by provisioning of resources to cloud user’s on-demand basis in pay-as-you-say-manner. Load Balancing may even support prioritizing users by a...

Cloud computing offers a wide range of benefits including potential cost-savings by leasing resources from cloud service providers and improved user experience by Geodistributing applications [17]. Cloud service providers typically share the platform and cloud resources across multiple users for better utilization. They lease resources on-demand to users in three broad flavors, namely, Infrastr...

The Cloud Computing model leverages virtualization of computing resources allowing customers to provision resources on-demand on a pay-as-you-go basis. During recent years, the power consumption of datacenters in cloud environment attracted researchers. Optimization of energy consumption can be performed by different methods including virtual machine (VM) consolidation. This technique can reduc...
