In this paper, the performance of the operational Level 2 MIPAS processor for offline data (versions 4.61 and 4.62) in the presence of cloud is examined. Using simulations of typical cloud scenarios, based on MIPAS cloud statistics for the tropics, the impact of varying cloud influence at 12 km and the tangent altitude above (i.e. 15 km) is investigated. It is found that with increased cloud pr...

Cloud is becoming the next-generation computing paradigm for enterprises to deploy services and run business. While most Cloud service providers promise some Quality of Service (QoS) through a Service Level Agreement (SLA), it is very hard for Cloud clients to know what impacts these QoS have on their businesses. In this paper, we study this issue by conducting a simple performance evaluation o...

In this article, we provide a cloud-security checklist for IaaS cloud deployments. The elements of the checklist are established by surveying the related literature on cloud-threat models and various security recommendations. We define the elements of the list on a level of abstraction that helps keep the size of the list manageable while preserving the lists practical applicability.

Oversubscription can leverage under utilized capacity in the cloud but can lead to overload. A cloud provider must manage overload due to oversubscription for maximizing its profit while minimizing any service level agreement (SLA) violations. This paper develops an understanding of oversubscription in cloud through modeling and simulations, and explores the relationship between overload mitiga...

The management of today’s service level agreements on the cloud market is often nontransparent and inefficient for the customer and the provider. However, service level agreements are crucial for establishing trust between all participants, especially for companies whose success depends on the purchased cloud service with its appropriated service quality. This thesis aims to improve the current...

Management and establishment of Service Level agreement (SLA) in cloud totally depends upon the various parameters which helps in establishment of SLA between the service providers and users. These parameters are the deciding factors for provisioning of services and in formation of SLA metrics. In this paper, we have analyzed probable parameters that can form or act as a SLA for entire cloud sy...

cloud point extraction and spectrophotometric determination of trace quantities of cadmium in some vegetables have been developed. the research area for vegetables analysis was near to the zarin shahr where the soil received heavy metals from the esfahan steel company. cloud point extraction used dithizone as complexing agent and non ionic surfactant triton-x114 as micellar phase. several impor...

The developing world's cloud computing sector has received considerable attention from global and local IT players, national governments, and international agencies. For example, IBM has established cloud computing centers in China, India, Vietnam, Brazil, and South Korea. Other global cloud players such as Microsoft, VMware, Salesforce, Dell, and Parallels are actively searching for opportunit...
