switches, and to each other, to provide connectivity between the various distribution
layer switches.

maximum hops for nodes ae nly a single hop over spin switches.
Characteristics of having an on-premises data center?
→ ~~> With an On-premise deployment, it might be easier to meet compliance
requirements
With an On-premise deployment, it might be easier to maintain a good user experience
