OpenStack and OVN Integration: Exploring The Architecture, Benefits, and Future of Virtualized Networking in Cloud Environments

Abstract

OpenStack, an open-source cloud computing platform, has emerged as a cornerstone for building and managing virtualized infrastructure in modern data centers. As cloud deployments grow in complexity and scale, there is an increasing demand for efficient and scalable networking solutions. Enter OVN (Open Virtual Network) - an open-source project designed to provide advanced virtual networking capabilities tailored for cloud environments. This paper delves into the intricate integration of OpenStack with OVN, offering a comprehensive overview of their combined architecture and the pivotal role of the Neutron networking service in this amalgamation. We discuss the myriad benefits that OVN brings to OpenStack deployments, including enhanced scalability, programmability, and network virtualization. The paper further elucidates the key components of OVN within an OpenStack environment and provides a deep dive into its operational mechanics. We also touch upon the limitations of OVN and its applicability in Network Function Virtualization (NFV) scenarios. As the landscape of cloud networking continues to evolve, understanding the synergy between OpenStack and OVN becomes paramount. This paper aims to provide readers with a holistic understanding of this integration, its implications for future cloud deployments, and the potential challenges and solutions in harnessing the full potential of virtualized networking.
