Cloudflare Performance Services

Anycast Network

With 150+ data centers across 60+ countries and 15 Tbps of capacity, Cloudflare’s Anycast network caches static content at the edge, reducing latency by delivering assets as close as geographically possible to visitors.

DNS

Cloudflare’s DNS shaves crucial milliseconds off requests for a DNS lookup. Because DNS query time could occur for every request, latency from DNS servers can slow down a site. Cloudflare’s DNS is the world’s fastest managed DNS provider, according to DNSPerf.com.

Support for Web Standards

TLS 1.3 with 0-RTT resumption reduces the amount of time for each “handshake” to establish a secure connection. HTTP/2 compresses the headers, making each payload smaller, allows a single connection to multiplex several requests in parallel, reducing the performance “expense” of total handshake round trips.

Content Delivery Network (CDN)

Enables applications to continue to serve static content, even when their origin servers are unavailable. Reduces risk of downtime by keeping requests for static content off the origin.

Web Content Optimization

Cloudflare includes a suite of web optimizations to improve the performance of Internet assets. Optimizations include the latest web standards, such as HTTP/2 and TLS 1.3, as well as proprietary enhancements for images and mobile device visitors.

Argo Smart Routing

Smart routing finds the fastest, least congested path, from the visitor to the origin and accelerates how traffic is sent within the Cloudflare network. By sampling round trip times along the Cloudflare network, Argo intelligently routes traffic to ensure performance delivery of dynamic content from the origin.

Railgun™

Accelerates dynamic or uncacheable content by compressing responses from the origin with an agent on the server.

China Network

With 21 data centers in China, Cloudflare accelerates and protects the delivery of content to customers in China, which has nearly 1.5 billion mobile users, 75% of whom access the Internet through their mobile device.

Load Balancing

Uses global health checks to identify offline origin server in order to route traffic to another online server or data center to ensure application availability. Automatic failover minimizes downtime, and alerts on down origins speed up problem discovery and failure resolution.

Mobile Optimizations (Mirage)

Enhances Cloudflare’s web content optimization for mobile users by “virtualizing” images—sending them initially as a lower-resolution—and consolidating them into a single request.

Stream

Cloudflare Stream makes streaming video easy by handling data storage, media encoding, content embedding and playing, regional delivery, and analytics.

Mobile SDK

Mobile SDK provides developers with network metrics that allow them to measure the impact of cellular network congestion and latency on mobile app performance. Cloudflare’s proprietary ‘ASAP’ protocol, built into Mobile SDK, ensures fast mobile experiences.
