Complete Control

We cache static, long tail, and rapidly changing content, as well as small objects and streaming video. Fastly allows businesses to both increase performance and reduce back-end costs through aggressive caching that can reduce origin traffic by 50-80%. We also help improve the overall experience for our customers’ end users — making web pages and the content on them (text, videos, images) load faster.

Instant Purge

Fastly can instantly purge any type of content in 150 milliseconds or less. This could take more than 15 minutes with traditional CDNs, which is a huge improvement, especially for ecommerce platforms, mobile apps, media sites, and any other industry where operating in real-time is a competitive advantage.

Built for developers, by developers

Fastly works like a developer thinks, with total transparency. We’re not a black box. You can access the full Fastly UI within your Heroku dashboard via single sign-on (SSO), which displays real-time analytics, historical stats, and all of the configuration settings. Furthermore, our API allows companies to treat Fastly as an extension of their infrastructure. Deploy custom configurations instantly and monitor performance in real time.

Expert Support

A joint Fastly-Heroku support team is there for you 24/7. We proactively identify issues to ensure everything is working smoothly. We don’t wait for tickets to come in — we look out for abnormal traffic patterns or network reachability problems. It’s our goal to alert you to issues before they affect performance.

Reduce Dyno Load

Fastly can drastically reduce Dyno load by serving more requests from the edge, decreasing hosting costs and improving request response time.

TLS Support

Fastly on Heroku gives you the ability to handle HTTPS requests out of the box by adding an apex domain (e.g. example.com), a subdomain (e.g. blog.example.com), or a wildcard domain (e.g. *.example.com) to your dedicated TLS certificate. Please refer to these steps to verify domain ownership.

Built on Varnish

We’ve built our global network on the open source Varnish Cache, and we load our cache servers with 10Gb Ethernet, hundreds of GB of RAM, and all Solid State Drives (SSDs) to guarantee flexibility and the power to scale.

Varnish allows Fastly customers to instantly purge content in 150 milliseconds or less. We’ve built a distributed system that synchronizes purges across all of our global caches, and our Varnish-based caches have up to 12x the performance and capacity of traditional caches. This allow us to offer new capabilities that traditional content delivery networks can’t provide.
