A Comprehensive Survey of Cloud Networking Architectures, Technologies, and Their Evolution in the Era of Digital Transformation

Abstract

The rapid advancement of cloud computing has catalyzed significant changes in networking architectures, technologies, and operational paradigms. This survey provides a comprehensive examination of cloud networking, tracing its evolution and highlighting critical developments in response to the digital transformation era. We explore foundational concepts, key technologies, and emerging trends shaping cloud networking. Furthermore, the paper delves into the architectural innovations, such as software-defined networking (SDN) and network function virtualization (NFV), that have facilitated scalable, flexible, and efficient cloud infrastructures. We also discuss the impact of artificial intelligence (AI) and machine learning (ML) on optimizing network performance and security. Through a detailed analysis of existing literature and current industry practices, this survey aims to offer a holistic understanding of cloud networking's trajectory and its future directions in the context of digital transformation.
