The observations of on-board satellite imaging radiometers are representative of a far-reaching two-dimensional cloud top properties, however with a cutback in the capacity of profiling the cloud vertically. A combination of simulated radiances calculated at the top of the cloud in the near-infrared (IR) and thermal infrared part of the spectra, is used as a proxy to estimate in-cloud droplet g...

a r t i c l e i n f o The lidar and radar profiling capabilities of the CloudSat and Cloud-Aerosol Lidar and Infrared Pathfinder (CALIPSO) satellites provide opportunities to improve the characterization of cloud properties. An Arctic cloud climatology based on their observations may be fundamentally different from earlier Arctic cloud climatologies based on passive satellite observations, whic...

Security undoubtedly play the main role of cloud CRM deployment, since the agile firms utilized cloud services in the providers infrastructures to perform acute CRM operations. In this paper researcher emphasis on the cloud CRM themes, security threads the most concern. Some aspects of security discussed concern on deployment the cloud CRM like: Access customers’ database and control; secure da...

The technology of cloud computing has attracted wide attention since its beginning, and it will become the mainstream in IT industry of next step. However, the future situation of cloud computing technology is still in initial stage, because the technology of cloud computing is burgeoning. So the conception of super cloud and super cloud language is proposed by referring to the development rout...

This paper provides a state-of-the-art review of cloud testing. Cloud computing, a new paradigm for developing and delivering computing applications and services, has gained considerable attention in recent years. Cloud computing can impact all software life cycle stages, including the area of software testing. TaaS (Testing as a Service) or cloud testing, which includes testing the cloud and t...

Cloud computing is getting popular and IT giants such as Google, Amazon, Microsoft, IBM have started their cloud computing infrastructure. However, current cloud implementations are often isolated from other cloud implementations. This paper gives an overview survey of current cloud computing architectures and S&V (security & vulnerabilities), discusses issues that current cloud computing imple...

Cloud Security threats have greatly hindered the development of Cloud Computing and the promotion of cloud application, so how to protect the data stored in the cloud is not only the core issue of security, but also the biggest challenge of development. As these problems above, a trust-control architecture based on the concept of Cloud Storage Service was creatively proposed. Based on the struc...

In cloud computing it is assumed that a single cloud with increased service demands because of the limitations of the hardware and software resources, can encounter overload. Cloud Federation is an ideal solution to overcome these problems. There are different types of single and hybrid clouds in Cloud Federation. Also, one of the aspects of union activity is based on borrowing hardware and sof...

Mobile cloud computing has grown out of two hot technology trends, mobility and cloud. The emergence of cloud computing and its extension into the mobile domain creates the potential for a global, interconnected mobile cloud computing environment that will allow the entire mobile ecosystem to enrich their services across multiple networks. We can utilize significant optimization and increased o...

Enterprises are driving towards less cost, more availability, agility, managed risk all of which is accelerated towards Cloud Computing. Cloud is not a particular product, but a way of delivering IT services that are consumable on demand, elastic to scale up and down as needed, and follow a pay-for-usage model. Out of the three common types of cloud computing service models, Infrastructure as a...
