With the increase in an online transactions and interactions on the internet, a key issue is how to use efficient and simple evaluation method to achieve trust based decisionmaking for service users and service providers. Trust plays an important role in all commercial cloud environments. It is the evaluation of capability of service providers as well as service users in completing a task based...

This research sets out to help computational modellers to select the most cost effective Cloud service provider. This is when they opt to use cloud computing in preference to in-house HPC facilities. Cloud computing is a pay-per-use model for accessing computing resources from a variety of service providers such as Amazon EC2. Increasingly cloud providers are offering the high performance compu...

The primary challenge of cloud service providers is finding ways to maintain a high degree of Quality of Service (QoS) in a cost-effective manner to ensure either profitability (for business-based cloud service providers) or cost avoidance (for government cloud service providers). The traditional approach to improving system performance is to upgrade the servers and/or network backbone, an expe...

Cloud computing is a rising field providing computation resources. It represents a new paradigm of utility computing and enormously growing phenomenon in the present IT industry and economy hype. The companies which provide services to customers are called as cloud service providers. The cloud users (CUs) increase and require secure, reliable and trustworthy cloud service providers (CSPs) from ...

Each computing system requires a platform that allows software to run. The computing platform includes a programming environment to create application software with a coherent operating system and processor. Each platform’s programming environment reflects a relevant abstraction, and usually the type and quality of the abstraction implies the complexity of problems we are able to solve. The Ser...

The Cloud computing paradigm offers numerous benefits to both Cloud users and service providers. However, a lack of trust between these two stakeholders has delayed the worldwide acceptance of Cloud for outsourced facilities. In this research work, a trust management framework has been proposed for effective selection of Cloud providers to fulfil numerous Cloud users’ requirements in a reliable...

Cloud computing is the use of computing resources such as hardware and software that are delivered as a subscription-based service and on demand services over a network. In cloud computing environments, there are two players: cloud providers and cloud users. Users always want to send their most sensitive data to cloud service centers, which is based on the trust relationship established between...

Different cloud computing service providers offer their customers' services with different risk levels. The customers wish to minimize their risks for a given expenditure or investment. This paper concentrates on consumers' point of view. Cloud computing services are composed of services organized according to a hierarchy of software application services, beneath them platform services which al...

In this paper, we address the problem of trust management in multi-cloud environments using a trust management architecture based on a group of distributed Trust Service Providers (TSPs). These are independent third-party providers, trusted by Cloud Providers (CPs), Cloud Service Providers (CSPs) and Cloud Service Users (CSUs), that provide trust related services to cloud participants. TSPs are...

Cloud Computing provides user a complete software environment. To serve resources to customers, Software as a Service providers rent resources from the Infrastructure as a Service Providers. Client applications and service providers negotiate for the sales of services by means of Service Level Agreement (SLA) that acts as a contract between them. Depending on the status of the demand, Infrastru...
