Q
Legacy networks run on expensive hardware such as routers and switches, which require time-consuming configuration and maintenance. In addition, these networks require expensive transport connections or carrier circuits to secure and segment the network. These carrier circuits might also not offer the bandwidth that is now required by users and modern applications hosted in private or public data centers.

5
Q
Legacy networks typically backhaul all branch traffic to the main data center for inspection and filtering. However, with advancements in cloud technologies, and wider adoption of cloud-delivered services, traffic flows have changed, with more traffic now being destined to the internet.
