Fastly Compute@Edge

Faster, simpler, and more secure serverless code.

Fastly’s Compute@Edge offering allows you to build high scale, globally distributed applications and execute code at the edge — without having to manage the underlying infrastructure. Deploy and run complex logic for any application or backend service with our secure, performant, and scalable approach to serverless computing.

Execute code faster

At 35.4 microseconds, Compute@Edge provides a 100x faster code execution startup time than other serverless solutions. Run your code on hundreds of servers located around the world simultaneously. There are no cold starts or roundtrip delays — just fast, always-on computing.

Enhance security and reliability

Operating within microseconds, our isolation technology helps protect you from side-channel attacks and diminishes resource contention while offering consistent performance you can count on. By creating and destroying a sandbox for each request that comes through the platform, we limit the blast radius of buggy code or configuration mistakes from other users and can reduce the attack surface area.

Build exceptional user experiences

Better end user experiences are at the forefront of digital transformation. Write, deploy, and test your code on the Fastly edge using a powerful local development and debugging environment. From there, we manage everything required to scale it instantly and globally, as close to your end users as possible.

Leverage familiar tools and languages

Developer experience and intuitive tool sets matter. With Compute@Edge, you can program in familiar languages, like Rust and JavaScript, port your code across cloud providers, and get an up-to-the-second view of your services. Plus, Compute@Edge seamlessly integrates into your existing tech stack.
