One of the main objectives of the smart city is to improve the quality of life. The information and communication technology (ICT) components are used as vital parts of the system. Increasing efficiency is the base of the smart city's sustainability. Therefore to increase the efficiency of ICT is crucial. Although cloud technology is just one possible building block of the ICT infrastructure its theoretical study used by the smart city is important because the cloud building technologies can be extended to the use of other ICT technologies. Because of these possibilities, one should study the potential regularities of cloud operation which affects among other things, the availability, capacity, flexibility and scalability topics as well.
