With the increasing numbers of Cloud Service Providers and the migration of the Grids to the Cloud paradigm, it is necessary to be able to leverage these new resources. Moreover, a large class of High Performance Computing (hpc) applications can run these resources without (or with minor) modifications. But using these resources come with the cost of being able to interact with these new resour...

Microsoft Windows Azure Cloud offers scalable resources to its customers. The price for renting the resources is linear, i.e. the customer pays exactly double price for double resources. However, not always all offered resources of virtual machine instances are most suitable for the customers. Some problems are memory demanding, others are compute intensive or even cache intensive. The same amo...

Endless resources provisioning illusion is the mainstay for cloud computing paradigm. However, the unpredictable volatility nature involving web applications workload demand would highly hinder cloud computing platforms performance, furthermore, expose cloud resources for possible devastation. Accordingly, this work proposes autonomic power aware SLA-oriented cloud resources orchestration two-t...

Cloud computing enables the sharing of resources such as storage, network, applications and software through internet. Cloud users can lease multiple resources according to their requirements, and pay only for the services they use. However, despite all cloud benefits there are many security concerns related to hardware, virtualization, network, data and service providers that act as a signific...

Cloud has emerged into another enhancement that manipulates the diversity of resources in order to expand the ability of Cloud facility. Cloud is no longer being seen as one-type service provider. The advantages of the heterogeneous Cloud give great benefits to the users and have business potential in service market. To cope with the dynamic nature of heterogeneous Cloud, the Cloud provider nee...

The expansion of telecommunication technologies touches almost all aspects life that we are living nowadays. Indeed, such technologies have emerged as a fourth essential utility alongside the traditional utilities of electricity, water, and gas. In this context, Cloud Data Center Networks (cloud-DCNs) have been proposed as a promising way to cope with such a high-tech era and with any expected ...

Cloud Computing provides the computational, storage, network and database resources to the consumers in a pay-as-per usage mode. In recent years, the data centers play a major role in hosting the cloud applications in the cloud infrastructure. The data centers are consuming huge electrical power and emits large amount of carbon footprint. It is essential to incorporate the Energy Efficient Reso...

The cloud computing model transforming the IT landscape. Cloud computing is a new computing paradigm that delivers computing resources as a set of reliable and scalable internet allowing customers to remotely run and manage these services. Infrastructure-as-a-service (IaaS) is one of the popular cloud computing services. IaaS allows customers to increase their computing resources on the fly wit...

This paper surveys the security problems of cloud computing as discussed in various research contributions. Cloud computing has been a hot researching area of computer network technology as well as data mining. As data mining requires large amount of data to be mined instead of investing for resources at the same place, cloud computing resources can be utilized. While outsourcing data to the mi...

Cloud computing is Modern day's wonder. It is not a product but a service, which provides shared resources, software, and information to computers and other devices like smartphones as a utility over a network mainly internet[1]. Resources namely memory, storage space, processor, etc are not available at user's end explicitly. Service providers own these resources and user access them...
