Preliminary Architecture of the Multi-Cloud Network Virtualization Infrastructure

Abstract

In this document we present the preliminary architecture of the SUPERCLOUD multi-cloud network virtualization platform. We start by defining the requirements of the architecture to then review the state-of-the-art. Namely, we survey Software-Defined Networking (SDN), the paradigm used in the proposed solution, and discuss recent SDN-based network virtualization platforms that offer insight into shaping the proposed design. As security is a first-class citizen in our architecture, we present a survey on security incidents involving public cloud services that motivates the need for self-management of network security. The document closes with the preliminary design of the SUPERCLOUD network virtualization platform with a focus on how the proposed architecture fulfills the requirements set as goal
