Our network is designed to provide fast, real-time digital experiences. Built on a highly customized version of Varnish, we use Varnish Configuration Language (VCL) and a global network of powerful servers to deliver intelligent caching and application logic at the edge.
Unlike traditional CDNs, Fastly’s edge cloud was built to take advantage of modern networking capabilities. Our POPs are comprised of powerful servers with 100% solid-state drives and plenty of RAM. They are strategically located in major metropolitan areas to take advantage of a higher density of Internet Exchange Points. We support the latest web protocols, including IPv6 and HTTP/2, for a faster, more secure browser performance.
Using Varnish Configuration Language (VCL), we enable you to perform intelligent caching and push application logic to the network edge, closer to your users. With our Edge Modules you can tailor how content is served at the edge based on a user’s location, language, or device type. Edge Dictionaries facilitate real-time edge decision making from every server on the Fastly network.
Fastly’s edge cloud platform is designed to deliver powerful real-time experiences. We give you the option to make your own configuration changes in seconds, unlike legacy CDNs where you need to engage Professional Services. Our logs and stats provide timely web performance insights for rapid troubleshooting. These features enable you to deploy code multiple times a day to support continuous integration / continuous delivery.
