Cloud computing is a standard futuristic computing model for the society to implement Information Technology and associated functions with low cost computing capabilities. Cloud computing provide multiple, unrestricted distributed site from elastic computing to ondemand conditioning with vibrant storage and computing requirement ability. Despite the probable gains attained from cloud computing,...

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...

In these recent years cloud computing paradigm has achieved widespread adoption. Its success is because of large customers’ ability to use services on demand with a payas-you go pricing model. Low costs and high flexibility make migrating to the cloud computing. Although having advantages, many companies hesitated to move to the cloud mainly because of conflicts related to the service facing th...

A cloud-detection method was used to retrieve cloudy pixels from Meteosat images. High spatial resolution (one pixel), monthly averaged cloud-cover distribution was obtained for a 1-year period. The seasonal cycle of cloud amount was analyzed. Cloud parameters obtained include the total cloud amount and the percentage of occurrence of clouds at three altitudes. Hourly variations of cloud cover ...

Knowing the metrics related to cloud is very critical to enhance the performance of the cloud. To learn the metrics related to cloud like the infrastructure, structure and functionality of the cloud systems many models were described. This paper lists some of the technical models related to the cloud computing that enhances the cloud performance. The models that are discussed focusses on some m...

With the development of IoT, Vehicular Ad-hoc Network will be shifted to Vehicular Ad-hoc Network managed cloud in near future. As the traditional cloud, VMM is a crucial problem in Cloud Based Vehicular Networks. Due to the distinct feature of high mobility, VMM Cloud Based Vehicular Networks need to be addressed to keep cloud services running on. When a vehicle moves on the road, it moves out...

Cloud computing is gaining tremendous momentum in both academia and industry. The application of Cloud computing, however, has mostly focused on Web applications and business applications; while the recognition of using Cloud computing to support large-scale workflows, especially dataintensive scientific workflows on the Cloud is still largely overlooked. We coin the term “Cloud Workflow”, to r...

Complexity of cloud infrastructures needs models and tools for process management, configuration, scaling, elastic computing and cloud resource health control. This paper presents a Smart Cloud Engine and solution based on a Knowledge Base, KB, with the aim of modeling cloud resources, Service Level Agreements and their evolutions, and enabling the reasoning on structures by implementing strate...

We will present progress on work to add cloud condensate control variable to a 4D-VAR analysis system at ECMWF. First, in 4D-VAR the linear physics scheme needs prognostic cloud variables to be able to use additional cloud information from observations, and in the current phase of our development the additional prognostic variable is cloud condensate (cloud liquid water and ice). Second, it is ...

Cloud-native applications are intentionally designed for the cloud in order to leverage cloud platform features like horizontal scaling and elasticity – benefits coming along with cloud platforms. In addition to classical (and very often static) multi-tier deployment scenarios, cloud-native applications are typically operated on much more complex but elastic infrastructures. Furthermore, there ...
