Global Content Delivery at the Edge

Fast, secure and reliable delivery of web applications and digital content through globally distributed infrastructure.

Points of presence across continents Anycast routing HTTPS delivery by default

What edge delivery means in practice

Instead of every request travelling to a single data centre, content is served from the location closest to the person requesting it.

Edge Delivery

Static assets, API responses and media are cached on edge servers spread across many regions. Requests are answered from the nearest point of presence, which cuts round-trip time and keeps the origin free for work only it can do.

Performance

Anycast routing sends users to the closest healthy node. HTTP/2 and HTTP/3 keep connections efficient, Brotli and gzip reduce transfer size, and tuned cache policies mean most requests never leave the edge at all.

Secure by Design

TLS termination happens at the edge with automatically issued and renewed certificates. Traffic between visitor and edge, and between edge and origin, stays encrypted end to end. Origin servers can be reached only through the delivery network.

Global Infrastructure

Points of presence on every populated continent, interconnected with major Internet exchanges and carriers. Capacity is distributed so that regional traffic peaks or a single node outage do not affect delivery elsewhere.

How a request travels

Three stages, and in the common case only the first two are involved.

Diagram: users connect to the nearest edge node; edge nodes fetch content from a single origin when it is not cached. Users Edge node Edge node Edge node Edge node Edge node Edge node Edge network (cache, TLS, routing) cache miss only Origin

Users

DNS and anycast routing direct each visitor to the nearest point of presence, wherever they connect from.

Edge network

The edge terminates TLS, applies caching rules and serves anything it already holds. Hot content never leaves this layer.

Origin

Only uncached or dynamic requests reach the origin, over a persistent encrypted connection, which keeps its load low and predictable.

Caching, availability and encryption

The details that decide whether a delivery network is merely fast or actually dependable.

Cache control you can reason about

Cache behaviour follows standard HTTP headers — Cache-Control, ETag, Vary — with the option to override TTLs per path or file type. Purging is available per URL, by pattern or for the whole resource, and propagates across the network within seconds.

Origin shielding

An intermediate caching tier collects requests from many edge nodes before contacting the origin, so a sudden spike in traffic from multiple regions results in a small number of origin fetches rather than thousands.

Automatic TLS

Certificates are issued and renewed without manual steps. Custom certificates can be uploaded where a specific chain is required. Modern protocol versions and cipher suites are enabled by default.

Availability across regions

Health checks remove degraded nodes from routing automatically. Because content is replicated across many locations, an incident in one region does not interrupt delivery in another.

Low-latency networking

Direct peering with large carriers and Internet exchanges shortens the network path. Connection reuse and early TLS negotiation keep first-byte times low even for uncached requests.

Real-time visibility

Delivery statistics — bandwidth, request counts, cache hit ratio, response codes by region — are available for monitoring and for tuning cache rules over time.

Built for modern applications

The same delivery layer works for very different kinds of traffic.

Websites

Pages, images, fonts and scripts served from the edge, with HTML caching for content that changes rarely.

APIs

Lower latency for read-heavy endpoints, TLS termination close to clients, and origin protection from traffic bursts.

Media

Large files and video segments delivered from cache, with range requests and adaptive bitrate streaming supported.

SaaS

A consistent experience for customers in different regions without deploying application servers everywhere.

Software delivery

Installers, updates and container images distributed globally, with predictable bandwidth costs at scale.
