Cloud of Practices is the preliminary outcome of a joint design and ethnographic research entitled Inhabiting and Interfacing the Cloud(s), which is documented and accompanied by two print-on-demand books. The main purpose of the field research presented in this first volume, Cloud of Practices, is to document the practices around cloud computing, as well as the user experience of cloud platforms. A combination of online research and interviews and observations with users has provided the insights for the Cloud of Cards design project which is the subject of the second eponymous book. The project is a set of digital and physical tools (‘cards’) that aims to give the designer, and particularly the maker community, the possibility to set up their own cloud infrastructure.
