Frameworks and Protocols for Achieving Interoperability in Multi-Cloud Networking: A Technical Perspective

Abstract

This paper provides a comprehensive technical perspective on the frameworks and protocols essential for ensuring interoperability in multi-cloud networking. The study begins by examining the fundamental challenges associated with multi-cloud interoperability, including disparate network configurations, security policies, and data management practices. It then explores various frameworks that facilitate interoperability, such as software-defined networking (SDN), network function virtualization (NFV), and service mesh architectures. These frameworks are analyzed in terms of their capabilities to abstract underlying network complexities, automate network provisioning, and manage cross-cloud traffic effectively. Furthermore, the paper delves into the protocols that play a crucial role in enabling multi-cloud communication. Key protocols discussed include Border Gateway Protocol (BGP) for inter-cloud routing, Virtual Extensible LAN (VXLAN) for overlay networking, and Internet Protocol Security (IPsec) for secure data transfer. The interoperability mechanisms of these protocols are evaluated, focusing on their performance, security, and scalability in multi-cloud scenarios.
