One of the notable tendencies in our rapidly developing world is information technology gaining ground in new (often unexpected) areas. A great example of this is the case of smart cities. Smart cities utilize Information and Communication Technologies (ICT) to improve liveability, make themselves more environmentally friendly, or reduce the costs of operation. Smart city solutions are still considered young today, but recent economical processes and environmental issues such as the global climate change have generated more interest than ever in the possibilities offered by this concept, and this is why more energy and resources need to be put into research in this area.
This thesis is the documentation of the planning, development, operation and improvement of a server application that is part of project SOLSUN, a European Union project which fits into the smart city concept. Its aim is to prove and present that a smart city infrastructure can be developed and maintained in a cost-effective way.
