Deploying cloud, fog and edge technologies in a smart city infrastructure: a comprehensive analysis of functional roles and security aspects

Abstract

The article provides a detailed analysis of the implementation of cloud, fog and edge computing technologies within the framework of the smart city infrastructure. Cloud computing offers extensive storage and computational scalability; edge computing minimizes latency by processing data at or near the data source; and fog computing serves as an intermediate layer that enables localized, context-aware processing with enhanced reliability. The theoretical foundations of these technologies, their functional features, as well as the relationship with data processing systems that provide operational management of smart city services are considered. Particular attention is paid to assessing security threats associated with distributed architecture, and recommendations are being developed to improve the resilience of information systems.
