Cloud network primarily enables a cloud computing infrastructure / solution, its associated components and external users/ application /services to communicate with each other. Typically, cloud network works similar to a standard computer network but its components / devices / operations are centered on cloud computing.
For example, a cloud network will enable connecting a remote user with a cloud application (SaaS) or cloud infrastructure (IaaS). User queries from a web browser/ internet are delivered to and from the remote/backend cloud infrastructure. Similarly, cloud network also enables the network communication between virtual machines
