We develop and evaluate an approach for generating Personalized Service Level Agreements (PSLAs) that separate cloud users from the details of compute resources behind a cloud database management service. PSLAs retain the possibility to trade-off performance for cost and do so in a manner specific to the user’s database.

The equilibrium climate sensitivity (ECS) of the two perturbed physics ensembles (PPE) generated using structurally different GCMs, MIROC3.2 and HadSM3, is investigated. We develop a method to quantify the SW cloud feedback by clouds with different cloud top pressure. We find that the difference in the ensemble means of the ECS between the two ensembles is mainly caused by differences in the SW...

Cloud computing is becoming increasingly attractive both in commercial and government sectors because of the significant cost reduction in their IT operations. The technical benefits of cloud environment (and its service-oriented capabilities) are the availability of computing resources those can quickly be engaged for service execution and released when no longer needed. As the cloud services ...

In recent times cloud computing has appeared as a new model for hosting and conveying services over the Internet. This model is striking to business vendors as it eradicates the requirement for users to plan in advance, and it permits the organization to start from low level and then add more resources only if there is an increase in the service demand. Even though cloud computing presents grea...

it is very important to determine the stable nitrogen isotope ratio for the nitrogenous substances in aerosols and the geochemistry behavior of stable nitrate ion isotopes in aerosols in order to elucidate the chemical and physical functions of clouds. hence, aerosol field sampling was conducted in the skies offshore from malibu beach and santa barbara, california, u.s.a. on 16 and 18 july 2009...

The use of Cloud Computing has increasedrapidly in many organization .Cloud Computing provides many benefits in terms of low cost and accessibility of data. In addition Cloud Computing was predicted to transform the computing world from using local applications and storage into centralized services provided by organization.[10] Ensuring the security of Cloud Computing is major factor in the Clo...
