For a decade the cloud meant a handful of enormous regions serving the entire planet. That model is breaking down. Latency-sensitive workloads — live commerce, multiplayer experiences, industrial sensing — are pushing computation back toward the user.
Why the shift is happening now
Three forces converged: cheap ARM silicon, mature container tooling, and carrier networks willing to lease rack space at the tower. Together they make a 10-millisecond round trip commercially viable.
What builders should do
Start by classifying workloads. Anything that is read-heavy and cacheable belongs at the edge today. Write-heavy transactional systems should stay centralised until your data layer supports regional consistency.
The teams winning here are not rewriting everything. They are moving one hot path at a time and measuring the result.
