As cloud adoption grows, the importance of preparing for forensic investigations in cloud environments also grows. A recent survey of digital forensic professionals identified that missing terms and conditions regarding forensic activities in service level agreements between cloud providers and cloud consumers is a significant challenge for cloud forensics. This paper addresses the challenge by...

a r t i c l e i n f o The lidar and radar profiling capabilities of the CloudSat and Cloud-Aerosol Lidar and Infrared Pathfinder (CALIPSO) satellites provide opportunities to improve the characterization of cloud properties. An Arctic cloud climatology based on their observations may be fundamentally different from earlier Arctic cloud climatologies based on passive satellite observations, whic...

The Cloud Bank model, which is derived from Grid bank [1], is a kind of commerce model of cloud computing that provides pay-as-you-go computing resources. In this model, Cloud Bank is an agent platform of resource transaction. Cloud computing uses the concept of service level agreement (S LA) to control the use and receipt of computing resources from, and by, Cloud Bank. As computing resources ...

The overlapping of high-level cirrus cloud and low-level stratus cloud has posed a major challenge in determining their cloud top altitudes using passive satellite observations. Chang and Li (2005) present a novel satellite retrieval method that takes advantage of the Moderate Resolution Imaging Spectroradiometer (MODIS) data to detect the presence of overlapped cirrus and stratus clouds and de...

This paper explores security issues of storage in the cloud and the methodologies that can be used to improve the security level. This study is concluded with a discussion of current problems and the future direction of cloud computing. Big data analysis can also be classified into memory level analysis, business intelligence (BI) level analysis, and massive level analysis. This research paper ...

One of the most promising field in computing is regarded as cloud computing, which allows users to store their data virtually over the cloud without the need of any fixed infrastructure. It offer user to manipulate their data regardless of the geographical position, hence providing a scalable, feasible and flexible way to connect user to their data. The cloud can be considered as of the Interne...

Cloud manufacturing is defined as a relationship between the consumer and a flexible array of production services, managed by an intervening architecture that can match service providers to product and manufacturing processes Cloud manufacturing definitions typically make explicit or imply three groups of actors: consumers, who request and use cloud manufacturing processes; application provider...

The spread use of virtual learning environments presents a great potential for the development of applications which meet educational area needs. In view of the importance of a more dynamic implementation and that it will be able to continuously adapt to the students needs, it was proposed and developed the U-SEA (System of Teaching Adapted Ubiquitous). A software built on the basis of virtual ...

The optimal contract design for cloud computing service with resource guarantee under the consideration of resource redundancy and network externality is studied in this research. A model in which a service provider determines joint pricing and resource allocation decisions is constructed by proposing two types of contracts with different service-level agreements (SLAs). The SLA of each contrac...

cloud computing refers to services that run in a distributed network and are accessible through common internet protocols. it merges a lot of physical resources and offers them to users as services according to service level agreement. therefore, resource management alongside with task scheduling has direct influence on cloud networks’ performance and efficiency. presenting a proper scheduling ...
