The use of digital content is increasing day after day and now it is an essential element of our day today life. The amount of stored information is so huge that it is highly difficult to manage the content especially in a distributed cloud environment. There are many open source software solutions available in cloud to handle huge amount of digital data. However none of these solutions addresses...
In this paper, we outline a tiered approach to auditing information in the cloud. The approach provides perspectives on auditable events that may include compositions of independently formed audit trails. Filtering and reasoning over the audit trails can manifest potential security vulnerabilities and performance attributes as desired by stakeholders.
The current implementations of cloud environment do not have suitable mechanism through which services can be managed to make use of cloud resources. The services in these environments can passively serve users' request only. If a service receives more requests than it can handle in a certain time period, it is subject to malfunctioning. This paper proposes a new approach to service replications that...
Web has become an open platform where everybody can build and run their applications. Big companies can manage the expenditure themselves. Small company or a single user wants to create web services, better they can rent the computing infrastructure. All the big companies are investing heavily on this Cloud technology. Few notable, important and popular cloud based products are g-mail and yahoo mail...
In this paper, we describe three major issues on supporting public cloud virtual machine such as the global scale. First is a heterogeneous provisioning issue. The kinds of operation systems that users require are various like as the required hardware performance diversity. Second, we propose a proper algorithm for guarantee about user's performance and efficiency of the cloud cluster resources together...
Aiming to discover the most suitable service cater to the discovery request of service consumer which includes functional requirements and nonfunctional requirements, this paper proposes a service registry model named as SRC (Service Registry on Cloud) which is an extension of the keywords based service registry model and deployed as a cloud application to provide behavior-aware and QoS-aware service...
Service Oriented Infrastructures including Grid and Cloud Computing are technologies in a critical transition to wider adoption by business. Their use may enable enterprises to achieve optimal IT utilization, including sharing re-sources and services across-enterprises and on-demand utilization of those made available by business partners over the network. This paper presents a selection of common...
Cloud computing is a new trend for computing resource provision. Many public clouds are available for developers to transfer or build web applications on cloud. As a result, the computing resource scheduling and performance managing have been ones of the most important aspects of clouding computing. In this paper, we propose a queueing-based model for performance management on cloud. In this model,...
Crowdsourcing is emerging as the new on-line distributed problem solving and production model in which networked people collaborate to complete a task. Enterprises are increasingly employing crowdsourcing to access scalable workforce on-line. In parallel, cloud computing has emerged as a new paradigm for delivering computational services, which seamlessly interweave physical and digital worlds through...
Cloud computing has emerged as a new technology that provides large amounts of computing and data storage capacity to its users with a promise of increased scalability, high availability, and reduced administration and maintenance costs. As the use of cloud computing environments increases, it becomes crucial to understand the performance of these environments. So, it is of great importance to assess...
