Enhancing Multi-Cloud Network Architectures for Scalability and Security in Global Enterprises

Abstract

In order to enhance scalability, flexibility, and resilience, multinational corporations are increasingly implementing multi-cloud strategies in the era of digital transformation. Enterprises can leverage the benefits of a variety of cloud service providers (CSPs), improve cost-effectiveness, and increase service availability across various locations by implementing multi-cloud network architectures. However, the management of such architectures poses significant challenges, particularly in terms of security and scalability. This article investigates methods for enhancing the scalability and security of multi-cloud systems, with a particular focus on cloud-native designs, software-defined networking (SDN), and hybrid cloud networking. It also addresses security concerns, including data privacy, identity management, and increased attack surfaces. It recommends solutions such as unified security management, Zero Trust frameworks, encryption, and multi-factor authentication (MFA). By implementing best practices such as frequent security audits, compliance tools, and network segmentation, enterprises can ensure robust performance, security, and regulatory compliance while efficiently managing multi-cloud systems. In a technological environment that is rapidly evolving, this study provides a comprehensive framework for organizations to improve their multi-cloud strategy by balancing scalability with stringent security protocols.
