Microsegmented Cloud Network Architecture Using Open-Source Tools for a Zero Trust Foundation
Sunil Arora, John D. Hastings · 2024
This paper presents a multi-cloud networking archi-tecture built on zero trust principles and micro-segmentation to provide secure connectivity with authentication, authorization, and encryption in transit. The proposed design includes the multi-cloud network to support a wide range of applications and workload use cases, compute resources including contain-ers, virtual machines, and cloud-native services, including IaaS (Infrastructure as a Service (IaaS), PaaS (Platform as a service). Furthermore, open-source tools provide flexibility, agility, and independence from locking to one vendor technology. The paper provides a secure architecture with micro-segmentation and follows zero trust principles to solve multi-fold security and operational challenges.
