Stateless edge functions are a solved problem. Replicate the code everywhere, route to the nearest node, done. The moment your function needs data, the difficulty reappears.
If every read goes back to a central database, you have reintroduced exactly the latency you moved compute to the edge to avoid. The data has to come closer too, and data is much harder to move than code.
CloudX offers a spectrum: eventually consistent key-value for data that tolerates staleness, and single-writer durable objects for data that needs strong consistency. The developer picks the trade-off per workload rather than getting one global answer.
Getting this layer right is what separates an edge platform from a glorified function-as-a-service. State is where the real value, and the real engineering, lives.
Latency is a feature you can ship.
Move your compute to the edge and give every user a local experience.
