Cloud infrastructures provide a rich set of management tasks that operate computing, storage, and networking resources in the cloud. Monitoring the executions of these tasks is crucial for cloud providers to promptly find and understand problems that ...

Analyzing the quantitative performance plays an important role in understanding and improving the quality of cloud computing systems and cloud-based applications. In cloud computing, service requests from users go through numerous provider-specific steps ...

The security issue has been a challenging concern for cloud computing because of the multitenant usage model. In cloud, each application normally runs on a dynamic coalition that is composed by multiple virtual machines (VMs) running on different ...

Governmental processes are often data-intensive and consume many resources. The basic idea of cloud infrastructures is that by sharing their resources, computing power and storage can be consumed real-time in a more efficient manner by a number of users. ...

Cloud computing infrastructures are providing resources on demand for tackling the needs of large-scale distributed applications. Determining the amount of resources to allocate for a given computation is a difficult problem though. This paper ...
