The document discusses the key role of networking in enabling cloud computing. It notes that the network is what connects users to cloud services and applications across data centers, clients, and other locations. It also outlines some of the challenges networks face in supporting cloud deployments at scale, such as unprecedented traffic growth. Finally, it proposes a "cloud networking" approach with four steps: 1) simplifying and scaling the data center network, 2) providing secure and scalable user access, 3) delivering a secure and elastic wide area network, and 4) orchestrating cloud services to optimize the user experience.
