Cloud computing is the latest evolution of computing where the IT resources are offered as services following the “pay-per-usage” pricing model. Cloud’s scalability feature causes variable price for resources governed by the cloud service providers. Therefore, the cloud customers’ main interest is whether the performance scales to the price for the leased resources in the cloud. In this paper w...

Upon the expansion of Cloud Computing and the positive outlook of organizations with regard to the movements towards using cloud computing and their expanding utilization of such valuable processing method, as well as the solutions provided by the cloud infrastructure providers with regard to the reduction of the costs of processing resources, the problem of organizing resources in a cloud envi...

Amazon’s Elastic Compute Cloud (EC2) leverages an auction approach, called “spot pricing”, to sell cloud resources to users. Spot prices are constantly adjusted by the cloud provider in response to demands, and users’ bids that exceed the spot price are accepted. When a user’s bid falls below the prevailing spot price, the user’s instance is terminated until such a time his bid exceeds the spot...

Cloud computing platforms such as Amazon EC2 provide customers with flexible, on-demand resources at low cost. However, while existing offerings are useful for providing basic computation and storage resources, they have not provided the transparency, security and network controls that many enterprise customers would like. While cloud computing has a great potential to change how enterprises ru...

The evolution of network technologies and their reliability on the one hand, and the spread of virtualization techniques on the other hand, have motivated the use of execution and storage resources allocated by distant providers. These resources may progress on demand. Cloud computing deals with such aspects. However, these resources are greedy in energy because they consume huge amounts of ele...

With the advancement of information technology need to perform computing tasks everywhere and all the time there, in cloud computing environments and heterogeneous users have access to different sources with different characteristics that these resources are geographically in different areas. Due to this, the allocation of resources in cloud computing comes to the main issue is considered a maj...

Edge computing is rapidly evolving to alleviate latency, bandwidth and Quality-of-Service concerns of Cloud-based applications as billions of ‘things’ are integrated to the Internet [1]. Current research has primarily focused on decentralizing resources away from centralized Cloud data centers to the Edge of the network and making use of them for improving application performance. Typically, Ed...

“Problem-solving environments” recently became a widely accepted approach to providing computational resources to solve complex eScience problems. This approach represents a problem as a workflow, orchestrating a set of various computational services. The existing cloud computing resources planning methods do not take into account a relation between such services, problem domain specifics, pred...

This paper considers a particular case of virtual organization composed of the following entities: institutions, online laboratories wishing to collaborate to share hardware and software resources. In the literature, cloud computing represents an implementation of the virtual organizations as grid computing. However, the benefits of the cloud are not used to the full in virtual organizations. T...

Cloud computing offers different type’s utilities to the IT industries. Generally the resources are scattered throughout the clouds. It has to enable the ability to find different resources are available at clouds, This again an important criteria of distributed systems. This paper investigates the problem of locating resources which is multi variant in nature. It also used to locate the releva...
