What Is Edge Rendering?
Edge rendering executes the code that produces a page on compute nodes distributed across many geographic locations, near the requesting user. Instead of every request reaching one origin region, it is served from a nearby point of presence. This shortens network round trips and can lower time to first byte.
Why it matters
Rendering near users reduces latency for a global audience, especially for dynamic pages that cannot be fully cached. The constraint is a more limited runtime than a full origin server.
