Network

Build on the world's fastest cloud network

Ship applications that feel instantaneous everywhere. Cloudflare's anycast network puts compute, storage, and security within <50 ms of 95% of Internet users no knobs to tune, no infrastructure to babysit.

Low latency by default

335+ cities with data centers and smart traffic routing cut round-trip times by up to 30%.

Global resilience

Anycast and automatic failover keep apps online even through regional outages or DDoS attacks.

AI inference

50+ models running close to users everywhere no GPUs to manage, no capacity planning.

Proven network infrastructure, powering products at scale

The same end-to-end network stack behind Cloudflare's own products battle-tested across billions of requests and millions of users daily. Build with the same primitives we use in production.

Realtime APIs and multiplayer games

When lag needs to be eliminated

High-traffic e-commerce

Online shopping and ticket sales where milliseconds = revenue

Startups

Hyperscaler performance without an ops burden

Built for global-scale applications

Everything you need to build, deploy, and scale network-optimized applications on Cloudflare's global infrastructure.

Anycast network (330+ cities)

One IP worldwide: traffic auto-lands at the closest edge for consistent low latency.

Argo smart routing

Dynamic, congestion-aware paths shave ~30% off median response time versus standard BGP routes.

Tiered & regional caching

Hot content stays near users while you control data-sovereignty boundaries.

Modern transport protocols

HTTP/3 & QUIC are enabled by default no config, no extra cost.

Global load Balancing & failover

Sub-second health checks with instant failover keep requests flowing during incidents.

Workers runtime

Serverless functions start in <5 ms cold-start, run near the requester, and scale globally.

Latency & origin insights

Built-in analytics surface per-country, per-colo, and per-route performance no extra agent needed.

Network reference architectures

with the tools to simplify them

Deploy globally-distributed applications between meetings.

[Background Pattern]

/index.ts

import { Hono } from 'hono'
import { cors } from 'hono/cors'

const app = new Hono()

app.use('*', cors())
app.get('/', (c) => c.text('Hello from the edge!'))

export default app

Smart routing included

Argo automatically finds the fastest path for each request, reducing latency by up to 30% with zero configuration.

Global load balancing for zero config

Automatically distributes traffic across multiple origins with health checks and failover built-in

Edge-first architecture

Built on Workers to provide an out of the box edge computing layer, with global distribution included

Build with global performance

Deploy once, run fast everywhere scale globally and handle traffic spikes with zero configuration.

Edge-optimized

Your code runs at the edge in 330+ cities worldwide with KV storage, D1 databases, and R2 object storage available globally.

Smart routing ready

Deploy both frontend and backend together from API routes to serverless functions, all with automatic optimization.

Resilient by design

Built-in DDoS protection, WAF, and failover keep your applications online during incidents.

[Duncan Davidson]

For Shopify, the real challenge is not about how many different pieces of complex technology we can use but the opposite. Cloudflare helps us find a simple way to achieve something very complex that we can scale and maintain.
