Multi-Cloud Role in the Future of Smart Cities IoT Architecture

Integrating multi-cloud approaches with smart city applications, particularly in the context of 5G/B5G and Open Radio Access Networks (O-RAN), presents significant opportunities for enhancing urban infrastructure and services. However, this integration also increases complexity and raises security and management issues that must be addressed to safeguard sensitive data and ensure the reliability and scalability of the system based on the technologies. This work discusses exploiting multi-cloud capabilities in Internet of Things (IoT) applications for smart cities, emphasizing the role of 5G edge computing while highlighting the associated challenges.
