BonFIRE offers a Future Internet, multi-site, cloud testbed, targeted at the Internet of Services community, that supports large scale testing of applications, services and systems over multiple, geographically distributed, heterogeneous cloud testbeds. The aim of BonFIRE is to provide an infrastructure that gives experimenters the ability to control and(More)
With increasing availability of Cloud computing services, this paper addresses the challenge consumers of Infrastructure-as-a-Service (IaaS) have in determining which IaaS provider and resources are best suited to run an application that may have specific Quality of Service (QoS) requirements. Utilising application modelling to predict performance is an(More)
For the last decade it has become commonplace to evaluate machine learning techniques for network based intrusion detection on the KDD Cup ’99 data set. This data set has served well to demonstrate that machine learning can be useful in intrusion detection. However, it has undergone some criticism in the literature, and it is out of date. Therefore, some(More)
BonFIRE is a multi-site test bed that supports testing of Cloud-based and distributed applications. BonFIRE breaks the mould of commercial Cloud offerings by providing unique functionality in terms of observability, control, advanced Cloud features and ease of use for experimentation. A number of successful use cases have been executed on BonFIRE, involving(More)
Future Internet applications are becoming increasingly dynamic and can be composed of a wide range of services controlled and hosted by di erent stakeholders. This paper addresses the challenge of resource provisioning for applications that have speci c Quality of Service (QoS) requirements and where consumers of Cloud resources want to avoid lock-in to any(More)
In the current hyperconnected era, modern Information and Communication Technology (ICT) systems form sophisticated networks where not only do people interact with other people, but also machines take an increasingly visible and participatory role. Such Human-Machine Networks (HMNs) are embedded in the daily lives of people, both for personal and(More)
We live in an emerging hyper-connected era in which people are in contact and interacting with an increasing number of other people and devices. Increasingly, modern IT systems form networks of humans and machines that interact with one another. As machines take a more active role in such networks, they exert an increasing level of influence on other(More)
