Points of Presence
PoPs
ELI5 — The Vibe Check
Points of Presence are the physical locations where a network has servers — data centers, co-location facilities, internet exchange points. When a CDN says 'we have 300 PoPs,' they mean your content is cached in 300 locations worldwide. More PoPs = more coverage = faster access for more people. It's real estate for your data.
Real Talk
Points of Presence (PoPs) are physical network access points distributed globally where service providers deploy infrastructure. In CDN and edge computing contexts, PoPs contain cache servers and compute resources that serve content and run code close to end users. They connect to internet exchange points (IXPs) for efficient routing.
