How long can a function run?
Execution limits depend on Fastly's Wasm runtime constraints, typically short-lived
Frequently Asked Questions about Fastly-compute-edge
What is Fastly-compute-edge?
Fastly Compute@Edge is a high-performance, serverless edge computing platform that allows developers to deploy code closer to users, enabling low-latency web experiences and fast content delivery.
What are the primary use cases for Fastly-compute-edge?
Dynamic content generation at the edge. Real-time personalization for websites and apps. Security enforcement (e.g., bot mitigation, access control). A/B testing and feature flagging without hitting origin. API responses caching and optimization at edge nodes
What are the strengths of Fastly-compute-edge?
Ultra-low latency by running code at the edge. Reduces origin server load. High-performance, event-driven execution. Tight integration with Fastly CDN. Supports modern WebAssembly runtimes for multiple languages
What are the limitations of Fastly-compute-edge?
Stateless by design; no persistent storage. Limited execution duration and memory per request. Requires understanding of edge computing concepts. Debugging and local testing is less straightforward than cloud environments. Vendor lock-in due to Fastly-specific platform features
