Cloud network: Technically, a cloud network is usually a WAN whose infrastructure is delivered through cloud services.
Computer system networks, especially people who make use of cloud-primarily based systems, can shop huge quantities of details and backups over a centralized remote server that's accessible to everyone, at any given time.
