Cloud computing is an emerging technology in distributed computing which facilitates pay per model as per user demand and requirement. Cloud consists of a collection of virtual machine which includes both computational and storage facility. The primary aim of cloud computing is to provide efficient access to remote and geographically distributed resources Cloud is developing day by day and face...

Considered the commercialization and the virtualization characteristics of cloud computing, the paper proposed for the first time an algorithm of job scheduling based on Berger model. In the job scheduling process, the algorithm establishes dual fairness constraint. The first constraint is to classify user tasks by QoS preferences, and establish the general expectation function in accordance wi...

In a Cloud computing environment, the workload fluctuates dynamically producing undesirable situations such as load imbalance, lower utilization or workload hotspots. In such cases, virtual machine migration is a potential solution. However, an algorithm based on a single objective (e.g. service-level agreement) is usually used to direct the migration process. On the contrary, there exist uncon...

Cloud computing is a computing advancement that provides a large number of computing and storage resources to different people. Management of huge amount of data in cloud computing is done by VM consolidation. Nowadays, energy saving has become a key aspect in designing VM consolidation algorithms. Algorithms for selecting next VM have never given consideration to both power and data at the sam...

Green cloud computing aims at a processing infrastructure that combines flexibility, quality of services, and reduced energy utilisation. In order to achieve this objective, the management solution must regulate the internal settings to address the pressing issue of data centre overprovisioning related to the need to match the peak demand. In this context, we propose an integrated solution for ...

Web 2.0 applications as social networking websites deal with a dynamic and various transaction workload. A middleware approach can be considered as a suitable solution for facing those various workloads. However, even if the middleware resources may be distributed for scalability and availability, they can be a bottleneck or underused when the workload varies permanently. We propose a solution ...

Cloud Computing (CC) is a model for enabling on-demand access to a shared pool of configurable computing resources. Testing and evaluating the performance of the cloud environment for allocating, provisioning, scheduling, and data allocation policy have great attention to be achieved. Therefore, using cloud simulator would save time and money, and provide a flexible environment to evaluate new ...

Cloud Computing is facing an increasing attention nowadays as it is present in many consumer appliances by advertising the illusion of infinite resources towards its customers. Nevertheless it raises severe issues with energy consumption: the higher levels of quality and availability require irrational energy expenditures. This paper proposes a Pliant system based virtual machine scheduling app...

Cloud Computing provides on-demand access to a shared pool of configurable computing resources. The major issue lies in managing extremely large agile data centers which are generally over provisioned to handle unexpected workload surges. This paper focuses on green computing by introducing Power-Aware Meta Scheduler, which provides right fit infrastructure for launching virtual machines onto h...

 Abstract—Cloud Computing is an emerging area. The main aim of the initial search-and-rescue period after strong earthquakes is to reduce the whole number of mortalities. One main trouble rising in this period is to and the greatest assignment of available resources to functioning zones. For this issue a dynamic optimization model is presented. The model uses thorough descriptions of the opera...
