Mariano received a background in classical studies and was a classical musician before discovering that open source was the best result in terms of democracy that mankind could achieve from the time of Pericles. He is thus self-taught on Linux and almost on all technology on which the Internet is based, creating email infrastructure, hosting, DNS, virtualisation, storage, data centres and ISP. Then he created the first European multi-region public IAAS based on Openstack, with which in 2015 Enter became the official supplier of EU institutions. Today he works on "Automium", a DevOps automation platform that uses open source tools to build cloud infrastructures in just a few minutes. He continues to travel the world talking about Enter projects and European and global socio-technological scenarios. In his free time, he likes jogging, without looking at the weather but rather staring at the landscape, playing the guitar and with his daughter Federica.
