Cloud computing is a new terminology achieved by distributed, parallel and grid computing and a design pattern for large, distributed data centers. Cloud computing offers end customers a pay as go model. Quality of service plays an important factor in distributed computing. Cloud computing provides different types of resources like hardware and software as service via internet. Under cloud comp...

Feedbacks involving low-level clouds remain a primary cause of uncertainty in global climate model projections. This issue was addressed by examining changes in low-level clouds over the Northeast Pacific in observations and climate models. Decadal fluctuations were identified in multiple, independent cloud data sets, and changes in cloud cover appeared to be linked to changes in both local tem...

Today, Cloud Networking is one of the recent research areas within the Cloud Computing research communities. The main challenges of Cloud Networking concern Quality of Service (QoS) and security guarantee as well as its management in conformance with a corresponding Service Level Agreement (SLA). In this thesis, we propose a framework for resource allocation according to an end-to-end SLA estab...

Cloud computing is an innovative and promising paradigm that is leading to remarkable changes in the way inwhich hardware and software are designed and purchased, aswell as how IT systems aremanaged. However, the Cloud is a risky paradigm. For instance, the use of Cloud services, which usually are external assets to their consumers, implies unprecedented risks that must be taken into account. I...

Solving of tasks for Cloud Computing is impossible without maintaining of high availability level of Infrastructure as a Service (IaaS) Cloud. Several large IaaS Cloud providers try to solve this problem by means of increasing number of physical machines (PMs) in multiple pools. However, migrations of available PMs from one pool to another and also repairs, diagnostic instances of failed physic...

The Moderate Resolution Imaging Spectroradiometer (MODIS) is one of five instruments aboard the Terra Earth Observing System platform launched in December 1999. After achieving final orbit, MODIS began Earth observations in late February 2000 and has been acquiring data since that time. The instrument is also being flown on the Aqua spacecraft, launched in May 2002. A comprehensive set of remot...

Antarctic Mesoscale Prediction System (AMPS) forecasts of atmospheric moisture and cloud fraction (CF) are compared with observations at McMurdo and Amundsen–Scott South Pole station (hereafter, South Pole station) in Antarctica. Overall, it is found that the model produces excessive moisture at both sites in the midto upper troposphere because of a weaker vertical decrease of moisture in AMPS ...
