Infrastructure design in the modern era faces evolving challenges due to the increasing demands for low latency, real-time processing, and efficient data handling. Edge computing has emerged as a pivotal technology to address these challenges by bringing computation and data storage closer to the data source. This research paper explores the role of edge computing in contemporary infrastructure design. It delves into the fundamentals of edge computing, its benefits, architectural considerations, use cases, and challenges. Through in-depth analysis and real-world examples, we elucidate how edge computing is transforming infrastructure to support the demands of the digital age.
