Intelligent Systems Laboratory (http://www.intelligence.tuc.gr) participates with the 'Crete Node' (openstack cloud infrastructure) in the FIWARE Lab Infrastructure Federation (https://www.fiware.org/lab/), a sustainable pan-European open federation of test infrastructures, realized by the FIWARE project (https://www.fiware.org ). The FIWARE Lab infrastructure federation comprises 19 nodes and as such it can cope with large trial deployments and can serve the various needs of a broad set of Future Internet users and experimenters. Recently, 'Crete Node' has participated in the FIWARE Lab Recognition & Reward Programme, based on 3 levels of engagement accreditation (Bronze, Silver, and Gold) and has received the Silver label complying with the Silver quality validation criteria of its infrastructure.
