Cloud computing [23] is a promising paradigm for the provisioning of IT services. Cloud computing infrastructures, such as those offered by the RESERVOIR project, aim to facilitate the deployment, management and execution of services across multiple physical locations in a seamless manner. In order for service providers to meet their quality of service(More)
Service Clouds are a key emerging feature of the Future Internet which will provide a platform to execute virtualized services. To effectively operate a service cloud there needs to be a monitoring system which provides data on the actual usage and changes in resources of the cloud and of the services running in the cloud. We present the main aspects of(More)
This paper addresses the problem of managing highly dynamic network and service environments, where virtual nodes and virtual links are created and destroyed depending on traffic volumes, service requests, or high-level goals such as reduction in energy consumption. This problem will be one of the main technical challenges to be faced in the evolution(More)
The use of the Lattice monitoring framework as a fundamental part of a overlay management system for virtual networks is presented. Lattice has been specially designed for monitoring resources and services in virtualized environments, including virtual networks. Monitoring of virtualized resources and services has many criteria which are not relevant for(More)
Cloud computing is changing the way in which companies deploy and operate ICT based services. This paradigm introduces several advantages compared with traditional data centers, such as a great degree of flexibility, pay-per-use models, and rapid resource provisioning. However, the lack of a well defined supply chain for clouds and an associated information(More)
Virtual Networks are characterised as highly dynamic network environments, where topologies and nodes adapt rapidly to changes in user and service demands, user location and context changes, or resource constraints. This paper presents a rigorous assessment of an Information Management Overlay (IMO) suitable for monitoring virtual networks. The IMO system(More)
In this paper we present a service management platform and an architecture which integrates the features of IoT with the management features of modern autonomic network management, and many service features from the world of Services. We present an architecture for INOX, a robust and adaptable Service Platform for the Internet of Things and Inter-Connected(More)
