With cloud computing, the efficient management of resources is of great importance as an increased utilization of the available resources can result in higher scalability and significant energy and cost reductions. Experimental validation of novel resource management strategies is costly and time consuming, and often requires in-depth knowledge of and control over the underlying cloud platform. As...
Using Network Functions Virtualization (NFV), network functions are virtualized and chained together to provide a network service. Often, a service chain can be allocated in multiple different ways, making use of different physical or virtual network functions, resulting in varying quality of service and deployment costs. In this paper, we introduce customizable function chains, which model the services...
Cloud environments face a growing demand for application hosting, and applications consisting of multiple data-sources and storage components. The need to ensure service level agreements for these types of applications creates important challenges for cloud infrastructure providers. The main contribution of this paper is an optimal cost-effective model and two algorithms to map component-based data...
