1 !CHAOS: a Cloud of Controls
Workshop CCR – Frascati 25-29 Maggio 2015 Michele Tota on behalf of !CHAOS project

2 A Cloud of Controls Design and implementation of a prototype of Control as a Services: an infrastructure at national level which offers a cloud of services and procedures distributed and shared over the LAN/WAN, to monitor and control any hardware device, system or intelligent component and which provides resources to processing services, data logging and archiving. Workshop CCR – Frascati Maggio 2015
