A Resources allocation is one of the most important things in cloud computing because environment which work depends heterogeneous and there are many who request same service at time. Two criteria used to be considered. First, time for completing all required tasks on available resources secondly energy consumed extracted from number processes that complete those tasks. While uploading an appli...

Data centre virtualization creates an agile environment for application deployment. Applications run within one or more virtual machines and are hosted on various servers throughout the data centre. One key mechanism provided by modern virtualization technologies is dynamic resource allocation. Using this technique virtual machines can be allocated resources as required and therefore, occupy on...

Software development nowadays involves several levels of abstraction: starting from the programming of single objects, to their combination into components, to their publication as services and the overall architecture linking elements at each level. As a result, software engineering is dealing with a wider range of artifacts and concepts (i.e., in the context of this paper: services and busine...

This thesis is concerned with maximising the efficiency of hosting of service provisioning systems consisting of clusters or networks of servers. The tools employed are those of probabilistic modelling, optimization and simulation. First, a system where the servers in a cluster may be switched dynamically and preemptively from one kind of work to another is examined. The demand consists of two ...

Recent works have proposed a number of models and tools to address the growing needs and expectations in the field of e-Science. At the same time, the availability and models of use of networked computing resources needed by e-Science are rapidly changing and see the coexistence of many disparate paradigms: high performance computing, grid and recently cloud, which brings very promising expecta...

Resource provisioning plays a major role in the cloud computing environment due to increased number of cloud users. The user satisfaction level can be improves in the considerable manner by provisioning the resources to the users which can process them with more profit. In this research work, resource provisioning is done with the consideration of the objective called profit. The profit of clou...

Deciding where to handle services and tasks, as well provisioning an adequate amount of computing resources for this handling, is a main challenge edge systems. Moreover, latency-sensitive constrain the type location devices that can provide needed resources. When available are scarce there possibility some resource allocation requests denied. In work, we propose VioLinn system tackle joint pro...
