Abstract	The vision of smart cities promises an improved quality of life and urban management, but its realization faces challenges related to the increasing complexity of modern cities. Digital transformation, particularly the use of Digital Twin (DT) technologies, has emerged as a potential solution to address these challenges. This study explores the transformative role of DTs in smart cities and proposes design principles for the effective deployment of City Digital Twins (CDTs). The authors suggested a federated approach, that integrates existing domainspecific DTs to form a comprehensive representation of urban dynamics. They emphasized the importance of reusing existing artifacts, such as simulation models, in the development of CDTs to reduce effort and enhance accuracy. The study also highlights the need for continuous twinning, ensuring that both the physical and digital twins adapt to evolving stakeholder requirements and operational contexts. Furthermore, the authors discussed key challenges in building CDTs, including composability, model flexibility, interoperability, model life-cycle management, maturity, security, and privacy. The paper concludes by delineating future research directions, which encompass proposing a layered architecture for CDTs and subsequently implementing a use case within the DevOps framework to validate the proposed architectural model. © 2024 IEEE.
