Cloud services are increasingly being used for a variety of purposes, including e-mail, social networking, music streaming, calendar management, file storage etc. In recent times the evolution of cloud services from private applications to corporate usage has been observed. This has led to the question of how private and business cloud services can be dual-accessed through a single device, in p...

We describe a privacy manager for cloud computing, which reduces the risk to the cloud computing user of their private data being stolen or misused, and also assists the cloud computing provider to conform to privacy law. We describe different possible architectures for privacy management in cloud computing; give an algebraic description of obfuscation, one of the features of the privacy manage...

Hybrid cloud technology is becoming increasingly popular as it merges private and public clouds to bring the best of two worlds together. However, due to the heterogeneous cloud installation, facilitating a hybrid cloud setup is not simple. Despite the availability of some commercial solutions to build a hybrid cloud, an open source implementation is still unavailable. In this paper, we try to ...

Cloud computing, which evolved from grid computing, virtualisation and automation, has a potential to deliver a variety of services to the end user via the Internet. Using the Web to deliver Infrastructure, Software and Platform as a Service (SaaS/PaaS) has benefits of reducing the cost of investment in internal resources of an organisation. It also provides greater flexibility and scalability ...

Cloud computing is an on-demand computing model, which uses virtualization technology to provide cloud resources to users in the form of virtual machines through internet. Being an adaptable technology, cloud computing is an excellent alternative for organizations for forming their own private cloud. Since the resources are limited in these private clouds maximizing the utilization of resources...

Cloud Computing is an attractive research area for the last few years; and there have been a tremendous grows in the number of educational institutions all over the world who have either adopted or are considering migrating to cloud computing. However, there are many concerns and reservations about adopting conventional or public cloud based solutions. A new paradigm of cloud based solution has...

Cloud service providers typically provide different types of virtual machines (VMs) to cloud users with various requirements. Thanks its effectiveness and fairness, auction has been widely applied in this heterogeneous resource allocation. Recently, several strategy-proof combinatorial auction ...

Big data applications are constructed under the cloud environment to process the big data values. Public cloud provides easily scaled up and scaled down computing power and storage to everyone. Private cloud services are provided to group of people only. Big data can be used in disaster management, high energy physics, genomics, connectomics, automobile simulations and medical imaging applicati...

To make cloud computing model Practical and to have essential characters like rapid elasticity, resource pooling, on demand access and measured service, two prominent technologies are required. One is internet and second important one is virtualization technology. Virtualization Technology plays major role in the success of cloud computing. A virtualization layer which provides an infrastructur...
