From a scientific and research perspective, examining the City Brain is of particular importance as this system represents the intersection of smart cities, artificial intelligence, big data, and cybersecurity. Analyzing the architecture, modules, applications, benefits, and challenges of the City Brain can provide a conceptual and practical framework for the development of future urban management platforms. Furthermore, addressing the security dimensions and data governance in the City Brain paves the way for future research on designing smart, secure, and trustworthy urban systems. The City Brain is a new paradigm that views the city as a complex cognitive system capable of perceiving, processing heterogeneous data, learning, and making adaptive decisions. It acts as the central core in the smart city ecosystem, integrating data from various urban sources to provide real-time insights and predictive management. Developed operationally since ۲۰۱۶, with Alibaba Cloud playing a pivotal role, the City Brain represents an evolution from theoretical concept to a solution tackling megacity challenges like traffic and safety. It shifts urban governance from reactive to predictive management, promoting collaboration, resilience, and integrated control in megacities.
