Dispersed computing along with its three crucial elements and its inherent options continues to encounter several challenges. The division between the endpoint devices and the cloud can pose a problem for latency-sensitive applications such as disaster management and content delivery systems. Fog computing presents a novel paradigm to address these issues. The purpose of this paper is to present an in-depth analysis of fog computing, its evolutionearly computing models and its impact on healthcare and the emerging Tactile Internet technology. It offers an exploration of concepts underpinning fog computing and outlines evaluation guidelines with focus on heterogeneity, Quality of Service, variability, mobility and outsourcing-insourcing decisions. The study emphasizes fog computing’s potential in real-time data processing, privacy enhancement and ultra-low latency provision and it suggests further research on cooperative algorithms and service quality improvement.
