IaaS clouds offer on-demand computing resources to clients to offload the burden of IT infrastructure management. However, in order to do so, cloud clients must place full trust in the cloud infrastructure, from various cloud services to the administrators managing the infrastructure. Such trust is often unjustified given the recent evidence of vulnerabilities found in cloud services and threat...

[1] Aerosol-cloud relationships are derived from 14 warm continental cumuli cases sampled during the 2006 Gulf of Mexico Atmospheric Composition and Climate Study (GoMACCS) by the Center for Interdisciplinary Remotely-Piloted Aircraft Studies (CIRPAS) Twin Otter aircraft. Cloud droplet number concentration is clearly proportional to the subcloud accumulation mode aerosol number concentration. A...

ION LAYER FOR DEVELOPMENT AND DEPLOYMENT OF CLOUD SERVICES Abstract In this paper, we will present an abstraction layer for cloud computing, which intends to simplify the manipulation with virtual machines in clouds for easy and controlled development and deployment of cloud services. It also ensures interoperability between different cloud infrastructures and allows developers to create cloud ...

8 Cloud radiative kernels and histograms of cloud fraction, both as functions of cloud top 9 pressure and optical depth, are used to quantify cloud amount, altitude, and optical depth 10 feedbacks. The analysis is applied to doubled CO2 simulations from eleven global climate 11 models in the Cloud Feedback Model Intercomparison Project. 12 Global, annual, and ensemble mean longwave (LW) and sho...

This research analyzes the performance of a distributed cloud broker in a live cloud environment, utilizing a government owned, private, federated cloud. The paper explores functioning of a distributed cloud broker that assists in the provisioning of services to geographically distributed data centers. The data centers have volunteered to federate and expose their utilization metrics to each ot...

Cloud management stacks have become a new important layer in cloud computing infrastructure, simplifying the configuration and management of cloud computing environments. As the resource manager and controller of an entire cloud, a cloud management stack has significant impact on the fault-resilience of a cloud platform. However, our preliminary study on the fault-resilience of OpenStack—an ope...

Cloud has emerged as a new computing paradigm that promises to move into computing-as-utility era. Desktop Cloud is a new type of Cloud computing. It merges two computing models: Cloud computing and volunteer computing. The aim of Desktop Cloud is to provide Cloud services out of infrastructure that is not made for this purpose in order to reduce running and maintenance costs. This paper discus...

The relationship between satellite-derived low cloud frequency and the occurrence of tropical montane cloud forest (TMCF) in Taiwan was investigated. From daily MODIS cloud mask products between 2003 and 2012 the low cloud class was extracted and mean low cloud frequency was calculated for Taiwan. This low cloud frequency map was blended with an existing plot-based vegetation classification for...

with the rapid development of the internet, the amount of information and data which are produced, are extremely massive. hence, client will be confused with huge amount of data, and it is difficult to understand which ones are useful. data mining can overcome this problem. while data mining is using on cloud computing, it is reducing time of processing, energy usage and costs. as the speed of ...

in recent years, the banking industry has made significant changes in technology and communications. the expansion of electronic communications and a large number of people around the world access to the internet, appropriate to establish trade and economic exchanges provided but high costs, lack of flexibility and agility in existing systems because of the large volume of information, confiden...
