The digital transformation of all areas of life is accelerated in this decade by novel cloud services, e-infrastructures, data platforms and cyber-physical system integration. This broader scope of cloud computing calls for technically sound contributions that combine scale with convenience and reliability. Society and economy depend on cloud applications delivering compute power on demand in every location along data paths as a general service to the public, in analogy to conventional utilities. The engineering of such systems and applications calls for scientifically proven approaches, methods, tools and technologies.

Providing a forum to review and discuss possible solutions, UCC is the premier IEEE/ACM conference for areas related to Cloud Computing as a Utility where leading researchers and practitioners in this important and growing field gather on an annual basis.

After a period of enforced online meetings, we are looking forward to UCC 2021 being one of the first major conferences to be conducted in hybrid mode, permitting direct interactions between participants. The call for papers and other participation information is already on the website.
