Access Control Policies defines the user roles and their access rights to the confidential data. Finegrained access control on confidential data hosted in the cloud are based on fine-grained encryption of the data in which data owners are in charge of encrypting the data before uploading them to the cloud and re-encrypting the data whenever user credentials change. When data owners perform the ...
This study compares 1997–2011 observationally based cloud fraction estimates from six different platforms (three ground-based estimates and three satellite-based estimates) over the Southern Great Plains, United States. The comparisons are performed at multiple temporal and spatial scales. The results show that 1997–2011mean cloud fractions from the Active Remote Sensing of CLouds (ARSCL) and f...
Complexity of cloud infrastructures needs models and tools for process management, configuration, scaling, elastic computing and cloud resource health control. This paper presents a Smart Cloud Engine and solution based on a Knowledge Base, KB, with the aim of modeling cloud resources, Service Level Agreements and their evolutions, and enabling the reasoning on structures by implementing strate...
While we talk about monitoring, the performance and compliance aspects are only on focus, however, the fine grained access logs also needs to be maintained if a proper internal audit is to be realized at organization level. Also, we do need to maintain long term logs for auditing purposes at internal auditing. In generic monitoring services provided by most of the cloud vendors, the case of mon...
We introduce a game-theoretic framework to explore revenue sharing in an Edge-Cloud computing system, in which computing service providers at the edge of the Internet (edge providers) and computing service providers at the cloud (cloud providers) co-exist and collectively provide computing resources to clients (e.g., end users or applications) at the edge. Different from traditional cloud compu...
To ensure that the services are always-on and globally distributed, cloud service providers sacrifice consistency for availability. Most Cloud Service Provider’s provide only eventual consistency which is a form of weak consistency. Strong Consistency is required for certain applications which are interactive. In such cases an SLA is to be engaged between the Cloud Service Provider and the user...
Cloud computing is quickly becoming the infrastructure of choice for hosting data and software solutions for many individuals, businesses, and governmental organizations. While such systems may provide increased flexibility and utility, efficient and easily-managed cloud storage solutions that ensure data confidentiality are needed to maintain this trend. In this work, we propose an algebraic-b...
ISSN 2250 – 110X | © 2011 Bonfring Abstract--It is not an easy task to securely maintain all essential data where it has the need in many applications for clients in cloud. To maintain our data in cloud, it may not be fully trustworthy because client doesn’t have copy of all stored data. But any authors don’t tell us data integrity through its user and CSP level by comparison before and after t...
Subseasonal variability of the stratus/stratocumulus cloud deck over the subtropical southeast Pacific is studied using satellite and buoy observations as well as the NCEP–NCAR reanalysis. It is found that subseasonal variability in the stratus cloud deck is closely related to variations in surface wind velocity, water vapor, sea level pressure, and 500-hPa geopotential height. An increase in c...
As the size and complexity of Cloud systems increases, the manual management of these solutions becomes a challenging issue as more personnel, resources and expertise are needed. Service Level Agreement (SLA)-aware autonomic cloud solutions enable managing large scale infrastructure management meanwhile supporting multiple dynamic requirement from users. This paper contributes to these topics b...
