Fastly Compute@Edge
Fastly Compute@Edge is a serverless edge computing platform that allows developers to deploy and run custom JavaScript, Rust, or WebAssembly code at the edge of Fastly's global network. It enables low-latency processing of HTTP requests and responses, such as dynamic content generation, request/response manipulation, and API orchestration, without managing servers. This platform is designed for building performant, scalable web applications and services that benefit from edge execution.
Developers should learn Fastly Compute@Edge when building applications that require ultra-low latency, such as real-time APIs, dynamic content delivery, or security features like bot mitigation, as it processes requests closer to users. It's particularly useful for use cases like A/B testing, personalization, and caching logic at the edge, where traditional server-based architectures might introduce delays. This is ideal for teams leveraging Fastly's CDN and seeking to extend its capabilities with custom logic.
