The EU and the US are both engaged in large scale efforts to devise standards for cloud computing be it at infrastructure, service or application level. In order to support this dialogue, this EU-US event on standards for cloud computing is co-organized by the European Commission and the European Telecommunications Standards Institute (ETSI) in partnership with the US National Institute of Standards and Technology (NIST), EuroCIO and Eurocloud. The event is open to all and free of charge but prior registration is required.
