Smart edge architecture that runs compute close to users to cut round-trip time and reduce origin load.

High-performance content delivery with dynamic content caching and instant purge capabilities to speed up content delivery.

Two-layer caching design with edge nodes and Origin Shield to aggregate origin requests and improve cache hit rates.

Web application and API protection at the edge, with capabilities to detect and mitigate DDoS and other security threats before they reach the origin.

Integrations with DevOps toolchains to enable real-time configuration changes and automated sync from development to production.

Fine-grained cache controls that allow differentiated caching rules based on API endpoints and other conditions.

Designed for high availability and resilience to eliminate single points of failure and handle traffic surges.

Use Cases of Fastly Edge

E‑commerce sites offload personalized recommendations, real-time inventory checks, or dynamic pricing to the edge to reduce latency.

Media and streaming providers distribute video, GIFs and other assets efficiently, supporting real-time ad insertion and on-the-fly video processing.

Development teams accelerate API responses with edge caching to lower latency and reduce origin load.

Organizations pursuing cloud-to-edge architectures handle part of the compute at the edge to boost digital transformation and business agility.

Sites expecting traffic spikes or high concurrency use the scalable edge architecture to maintain stable service.

Developers iterate and deploy edge logic quickly using the platform console, APIs and SDKs for dynamic configuration.
