What is an Edge Network?
Edge networking moves computing power out of distant data centres and puts it close to the people using it. Here's how edge networks work, and why the internet is being rebuilt around them.
Edge network definition
An edge network is a distributed network of servers positioned close to end users — at the "edge" of the internet — rather than concentrated in a handful of central data centres. Because requests are handled by the nearest server instead of travelling to a distant facility, edge networks deliver lower latency, higher reliability, and lower bandwidth costs than centralised infrastructure.
The idea is simple: the speed of light is a hard limit. A request from London to a data centre in Virginia and back takes tens of milliseconds before any work is even done. Multiply that by every asset on a page, or every frame of a video call, and distance becomes the dominant cost. Edge networking removes the distance.
The network edge vs the network core
In networking terms, the core is the high-capacity backbone — the long-haul fibre routes and interconnection points that carry traffic between regions. The edge is where that backbone meets the real world: the last-mile networks, exchange points, and servers nearest to homes, offices, and devices.
Traditional cloud hosting lives deep in the core. Your application runs in one or two large facilities, and every user, wherever they are, has to reach those facilities across the backbone. An edge network inverts this: it stations edge servers at many points near users, so most requests never need to cross the core at all.
The two aren't in competition — the core still carries traffic between edge locations and back to origin systems. But the more work the edge absorbs, the faster and cheaper everything gets.

How CDNs relate to edge networks
A content delivery network (CDN) was the first mainstream use of edge networking. A CDN caches copies of static content — images, video, scripts, downloads — on edge servers around the world, so each user fetches files from a nearby cache instead of a distant origin.
Modern edge networks go further. Beyond caching, they run compute workloads, store data in object storage, and answer DNS queries at the edge. A CDN is one service an edge network can offer; the network itself is the underlying infrastructure. We cover the distinction in detail in CDN vs Edge Computing.
Why edge networks matter
The advantages of moving work to the edge compound: every request handled locally is faster for the user and cheaper for the operator.
Lower Latency
Requests are answered by a server physically near the user, cutting round-trip times dramatically.
Resilience
With many servers sharing the load, no single failure can take the network offline.
Global Reach
Users in every region get the same fast experience, without you deploying to multiple clouds.
Lower Costs
Serving content close to users reduces long-haul bandwidth and takes pressure off origin infrastructure.
How Edge builds its edge network differently
Most edge networks are built the traditional way: one company leases rack space in data centres around the world and fills it with its own hardware. That works, but coverage is limited by how many facilities one company can afford to run.
Edge takes a decentralised approach. Our network is made up of 998 nodes contributed by independent operators worldwide, who stake tokens to participate and earn rewards for the capacity they provide. Because anyone can add a node, the network grows where demand exists rather than where leases are cheapest — and there is no single company data centre whose failure can take it down.
On top of this network Edge runs a full set of services: a CDN with zero egress fees, object storage, compute and GPUs, and DNS — the components of what we call the edge cloud. You can read more about the decentralised model in What is a Decentralised Cloud?
