Secure and Scalable Multi Cloud Networking

Abstract
In the evolving landscape of network optimization and cyber security, traditional architectures struggle with demands for automation, agility, and Zero Trust compliance. This paper proposes an AI-augmented, Zero Trust-enabled framework for secure and scalable multi-cloud networking, integrating VXLAN EVPN, TLS 1.3 selective decryption, Scalable Group Tags (SGTs), and AI-based predictive operations. We present real-world configurations, discuss trade-offs and implementation challenges, and support our contributions with practical insights and data. While the individual components are well-established, their integration into a cohesive framework delivers tangible benefits.
