All About Cloud Regions, Zones, and On-Ramps


By Patrick ChristianApr 4, 2024


Today, I'm breaking down three fundamental components of cloud networks.

Cloud Regions. Regions are territories (generally, a metro area) that comprise one or multiple cloud zones.

Cloud Zones. These are typically individual data centers in a geographic region or on a campus. A local zone is an extension of a cloud region that offers a subset of standard cloud services that tend to be more latency sensitive. Local zones are accessible at cloud on-ramp locations.

On-Ramps. These are the points of interconnection between enterprises and cloud service providers (CSPs), often found in colocation facilities in the most interconnected cities.

Some CSPs tie on-ramps to specific regions in their own internal network. Usually there is a loose geographic correlation between the on-ramp locations and CSP data centers.

In the map below, you’ll see a glimpse of the connectivity landscape as of Q1 2024.
