Cloud network is referred to a computer network that exists within or is part of a cloud computing infrastructure.
It is a computer network that provides network interconnectivity between cloud based or cloud enabled application, services and solutions. Cloud network can be cloud based network or cloud enabled network.
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.
