In this paper, the authors focus on Cloud Computing, which is a distributed architecture that centralizes server resources on quite a scalable platform so as to provide on demand’ computing resources and services The authors outline what cloud computing is, the various cloud deployment models and the main security risks and issues that are currently present within the cloud computing industry. ...

Cloud computing may be defined as management and provision of resources, software, applications and information as services over the cloud (internet) on demand. Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. "Clou...

The availability of public computing resources in the cloud has revolutionized data analysis, but requesting cloud resources often involves complex decisions for consumers. Under the current pricing mechanisms, cloud service providers offer several service options and charge consumers based on the resources they use. Before they can decide which cloud resources to request, consumers have to est...

Provisioning extra resources is necessary when the local resources are not sufficient to meet the user requirements. Commercial Cloud providers offer the extra resources to users in an on demand manner and in exchange of a fee. Therefore, scheduling policies are required that consider resources’ prices as well as user’s available budget and deadline. Such scheduling policies are known as market...

Cloud computing provides the better resource sharing and utilization of services through virtual shared servers. The allocation and deallocation of resources effects on quality, processing, memory, and service provisioning. The automation of cloud computing services is a big issue till now This model provides the better utilization of resources on demand through an agent by using formal method ...

Dynamic services using the scalable and virtualized property over the network is provided in the cloud computing environment. The cloud computing does not effective in handling the normal resource allocation algorithms. The cloud computing schedulers make a decision on workflow allocation. Cloud always consumes a high communication cost than the known resource schedulers in large scale distribu...

Cloud computing provides users near instant access to seemingly unlimited resources, and provides service providers the opportunity to deploy complex information technology infrastructure, as a service, to their customers. Providers bene t from economies of scale and multiplexing gains a orded by sharing of resources through virtualization of the underlying physical infrastructure. However, the...

Cloud computing is a model of sharing computing resources over any communication network by using virtualization. Virtualization allows a server to be sliced in virtual machines. Each virtual machine has its own operating system/applications that rapidly adjust resource allocation. Cloud computing offers many benefits, one of them is elastic resource allocation. To fulfill the requirements of c...

Cloud computing is an architecture for facilitating computing service through the internet on requirement and pay per use access to a group of shared resources namely networks, storage, servers, services and applications, without physically acquiring them Cloud DBMS is a distributed database that gives computing as a service. It is sharing of web infrastructure for resources, software and infor...

Worldwide accessibility of clouds brings great benefits by providing easy access to resources. However, scheduling cloud resources for utilization among multiple collaborating cloud users is still often executed manually. To address this problem, we developed a scheduling service for cloud middleware that guarantees optimal resource utilization in terms of a total number of used resources in a ...
