Edge computing: 2 real scaling case studies
2 of the 73 engineering write-ups in our database are tagged with the technique "edge computing". They come from 2 companies (Cloudflare and Meta) and were published in 2026. 1 of the 2 state concrete scale numbers, for example "millions of databases" (Cloudflare). Each card below links to our short summary and the original post.
Under the hood, off the hot path: how D1 scales to millions of databases
How Cloudflare's D1 keeps query execution at the edge while a separate control plane manages millions of SQLite databases.
Shipping Media Over QUIC at Meta Scale for Instagram Live Ingest
Instagram Live ingest moved from Meta's in-house RUSH protocol to the open IETF Media over QUIC standard on iOS and Android. Edge endpoints translate MoQ frames into the RUSH format, so the backend did not change. Server-side routing let the experiment resize in minutes, the transport falls back to TCP when UDP is blocked, and the launch matched RUSH on quality and reliability.
