GoKawiilNetlify moves Edge Functions to Firecracker MicroVMs, cuts median latency 5x
Netlify has re-architected the infrastructure behind its Edge Functions, replacing a hosted execution service with Firecracker MicroVMs running directly on its own edge network. The company, working with Unikraft, says warm invocations now take roughly 5-6ms at the median, down from 25-40ms previously, while functions can still be written and deployed exactly as before.
GoKawiil's interpretation of the reporting above, not reported fact.
For sites using Netlify's edge functions for personalization, routing or auth, lower per-request latency directly shortens page load times experienced by end users. Netlify also says the new architecture improves security and reliability and could enable more complex compute workloads at the edge, though the extent of those gains will depend on real-world usage.
- Netlify Edge Functions now run on Firecracker MicroVMs instead of a hosted execution service
- Median warm-invocation latency dropped from 25-40ms to about 5-6ms
- Existing Edge Functions code, imports and configuration remain unchanged
