In these recent years cloud computing paradigm has achieved widespread adoption. Its success is because of large customers’ ability to use services on demand with a payas-you go pricing model. Low costs and high flexibility make migrating to the cloud computing. Although having advantages, many companies hesitated to move to the cloud mainly because of conflicts related to the service facing th...

Cloud computing is a pattern for delivering ubiquitous and on demand computing resources based on pay-as-you-use financial model. Typically, cloud providers advertise cloud service descriptions in various formats on the Internet. On the other hand, cloud consumers use available search engines (Google and Yahoo) to explore cloud service descriptions and find the adequate service. Unfortunately, ...

With the rapid popularity of cloud computing paradigm, disaster recovery using cloud resources becomes an attractive approach. This paper presents a practical multi-cloud based disaster recovery service model: DRCloud. With DR-Cloud, resources of multiple cloud service providers can be utilized cooperatively by the disaster recovery service provider. A simple and unified interface is exposed to...

Overview In cloud-infrastructure, cloud service providers (e.g. Amazon Web Service, IBM Cloud, Microsoft Azure) are not allowed to access the content of customer virtual machines. In consequence, it is hard for the providers to protect their infrastructure from malware infections. As the virtual machines are usually created from a limited set of standard images and likely share many vulnerabili...

Cloud computing is an emerging paradigm with three main facets: Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). Several benefits are expected from cloud-based conferencing (e.g. efficiency in resource usage, easy introduction of new conferencing applications). This paper proposes a publication and discovery architecture for the interactions bet...

Recent advance in cloud computing has transformed the way information is managed and consumed, since this new paradigm provides cost efficient solutions that allow the transmission, storage, and intensive computing of information. Therefore, Cloud service providers are increasingly required to take responsibility for the storage as well as the efficient and reliable sharing of information, thus...

Cloud computing is becoming a key factor in computer science. It represents a new paradigm of utility computing and enormously growing phenomenon in the present IT industry and economy hype. The cloud users (CUs) increase and require secure, reliable and trustworthy cloud service providers (CSPs) from the market. It’s a challenge for a new customer to choose the highly secure provider.
