Executive Summary Public cloud computing—delivering infrastructure, services, and software on demand through the network—offers attractive advantages to higher education. For example, it has the potential to reduce information and communications technology (IT) costs by virtualizing capital assets such as disk storage and processing cycles into a readily available, affordable operating expense....

The new developments in the field of information technology offered the people enjoyment, comforts and convenience. Cloud computing is one of the latest developments in the IT industry also known as on-demand computing. It provides the full scalability, reliability, high performance and relatively low cost feasible solution as compared to dedicated infrastructures. It is the application provide...

Existing cloud storage systems receive the data in its plain form and perform conventional (server-side) deduplication mechanisms. However, disclosing the data to the cloud can potentially threaten the security and privacy of users, which is of utmost importance for a real-world cloud storage. This can be solved by secure deduplication mechanisms which enables the user to encrypt the data on th...

In order to meet distributed application deadlines, Resource Management Systems (RMSs) have to utilize additional resources from public Cloud providers when in-house resources cannot cope with the demand of the applications. As a means to enable this feature, called Cloud Bursting, the RMS has to be able to determine when, how many, and for how long such resources are required and provision the...

Wireless Body Sensor Networks (WBSNs) are gaining importance in the era of the Internet of Things (IoT). The modern medical system is a particular area where the WBSN techniques are being increasingly adopted for various fundamental operations. Despite such increasing deployments of WBSNs, issues such as the infancy in the size, capabilities and limited data processing capacities of the sensor ...

An operation preceding most human DNA analyses is read mapping, which aligns millions of short sequences (called reads) to a reference genome. This step involves an enormous amount of computation (evaluating edit distances for millions upon billions of sequence pairs) and thus needs to be outsourced to low-cost commercial clouds. This asks for scalable techniques to protect sensitive DNA inform...

Using Cloud Storage, users can remotely store their data and enjoy the on-demand high quality applications and services from a shared pool of configurable computing resources, without the burden of local data storage and maintenance. However, the fact that users no longer have physical possession of the outsourced data makes the data integrity protection in Cloud Computing a formidable task, es...

The 21st century belongs to the world of computing, specially as a result of the so-called cloud computing. This technology enables ubiquitous information management and thus people can access all their data from any place and at any time. In this landscape, the emergence of cloud storage has had an important role in the last five years. Nowadays, several free-access public cloud storage servic...

Cloud computing becomes quite popular among cloud users by offering a variety of resources. This is an on demand service because it offers dynamic flexible resource allocation and guaranteed services in pay as-you-use manner to public. In this paper, we present the several dynamic resource allocation techniques and its performance. This paper provides detailed description of the dynamic resourc...

Open source IaaS is hot topic in cloud computing and every year a new IaaS with a different design is announced. This paper provides a closer look into three common IaaS; Eucalyptus, OpenStack & Nimbus. OpenStack is currently the best choice of public cloud providers due to its aim at standardization and scalability while Eucalyptus is more appropriate for private cloud deployments.
