Building an efficient broker overlay network for publish/subscribe systems to support large-scale distributed applications is a challenging issue today. In this paper, we propose a Fog/Cloud based data delivery model that organizes a hierarchy of brokers and participants for event delivery. We use an ensemble of ZooKeeper servers to facilitate coordination among components and devise new procedures...
With virtualization technique, cloud computing is developed rapidly. However, aspects of the collecting of digital proofs for forensics in cloud computing environment, certain guideline is not yet. Therefore, cloud forensic researches in progress for reactivating security incidents in cloud computing. In this paper, we analyze forensic issue, challenges, already proposed forensic model in previous...
Still lacking a standard architecture, cloud computing requires sophisticated ways to estimate resources for the requesting cloud service customers (CSCs). CSC show random behavior in utilizing various services. In this regard, if all the CSCs are treated in the same way, not only cloud service providers (CSPs) suffer because of uctuating utilization behavior of CSCs, but also CSCs suffer, since they...
Rapidly increasing digital media has triggered the importance of cloud computing. Cloud computing provides ease of management and ubiquitous access facility to the growing digital content. The ratio with which digital content has been increasing, it now requires multiple clouds to interoperate for the purpose of scalability, efficient service provisioning, and better management. This scenario is known...
Cloud computing has rapidly developed with emergence of various user mobile devices. Furthermore, Cloud Service Broker (CSB) is emerged, as service mediation is willing to provide profit of a cloud customer as well as a cloud service provider in cloud environment. As a result, cloud computing nowadays has the architecture, which can provide extended services by collaboration among service providers...
Digital media content has increased massively due to which, cloud computing is rapidly gaining importance. Cloud computing not only provides ubiquitous access, but also, ease of management of hugely increasing data. The next era is going to be of cloud federation, in which services would be brought up to the user through multiple clouds, creating an Inter-Cloud computing environment. One of the key...
Cloud Computing is a dominating computing paradigm with its significant impact on the distribution of computing resources and business attribution. However, due to the lack of fairness in pricing and SLAs during the service in cloud computing, customers are dissatisfied with the existing pricing model of current situation, and there have an immense chance to lose those dissatisfied customers. Therefore,...
Today, the rapid growth of the large-scale appli-cations conduces to a difficult challenge to individuals as well as the commercial organizations due to the limitation of the local computing resources. Meanwhile, the extension of the local computing platforms requires a huge investment about both finance and human power. Therefore, the use of nearly-unlimited resources and on-demand scaling of Cloud...
Cloud computing is an evolving term these days. It describes the advance of many existing IT technologies and separates application and information resources from the underlying infrastructure. Personal Cloud is the hybrid deployment model that is combined private cloud and public cloud. By and large, cloud orchestration does not exist today. Current cloud service is provided by web browser or host...
In Web environment, multiple Web service(WS)s may provide similar functionalities with different nonfunctional property values (e.g. different QoS metrics). Quality of service (QoS) metrics of WSs are critical factors to select appropriate WSs execution path in WSs composition as it requires expensive computation cost to find out appropriate execution path in Web environment, i.e O(MN) assuming that...
Now-a-days, many high-end applications are turning to grid computing to meet their computational and data storage needs. High-end applications require a wide variety of computational resources as well as long time to produce the desired output. These resources should be utilized efficiently and effectively for overall performance improvement. In this paper, we present an efficient resource management...
