Networks connecting distributed cloud services through multiple data centers are called cloud networks. These types of networks play a crucial role in cloud computing and a holistic performance evaluation is essential before planning a converged network-cloud environment. We analyze a specific case where some resources can be centralized in one datacenter or distributed among multiple data cent...

Cloud computing has recently become an attractive solution for massively multiplayer online games, also known as MMOGs, as it lifts operators from the burden of buying and maintaining large amount of computational, storage and communication resources, while offering the illusion of infinite scalability. Yet, cloud resources do not come for free: a careful orchestration is needed to minimize the...

Cloud computing is a delivery platform which promises a new way of accessing and storing personal as well as business information. It provides resources to its users through the Internet. But it also has a risk that is the involvement of a third party which makes it difficult to trust that user data is secure enough and will not be misused. To provide security, new technology called Fog computi...

Cloud computing helps to share data and provide many resources to users. Users pay only for those resources as much they used. Cloud computing stores the data and distributed resources in the open environment. The amount of data storage increases quickly in open environment. So, load balancing is a main challenge in cloud environment. Load balancing is helped to distribute the dynamic workload ...

In cloud computing, the resources are provided as service over the internet on demand basis. The resources such as servers, networks, storage, applications are dynamically scaled and virtualized. The demand grows gradually for each virtual machine in a cloud computing environment over time. So, it is necessary to manage the resources under each cluster to match the demand in order to maximize t...

Cloud computing refers to Internet based distributed computing where the physical resources are pooled at one end and users across the globe can have access to unlimited resources as payasyou-go utility computing model. Cloud service users requests computing resources and cloud service provider provides them as virtual machine (VM) instances. The problem addressed here is dynamic VM creation an...

In the simplest way, cloud computing means classifying and getting data and programs over the Internet instead of your computer's hard disk drive. It is a dissemination of computing resources—everything from applications to data centers over the Internet on a reward-for-use basis. Cloud computing is mostly defined as a type of computing that focuses on sharing computing resources rather of...

Cloud computing is a specialised form of distributed computing that introduces utilization models for remotely provisioning scalable and measured resources. The driving motivation behind the cloud computing is to provide IT resources as a service that encapsulates other IT resources. Data service outsourcing is one of the service that is economically enabled by the cloud computing. But in order...

Cloud computing aims to give users virtually unlimited pay-per-use computing resources without the burden of managing the underlying infrastructure. We claim that, in order to realize the full potential of cloud computing, the user must be presented with a pricing model that offers flexibility at the requirements level, such as a choice between different degrees of execution speed, and the clou...
