Now, let’s try a much better, O(1) control plane. DUMB AS ROCKS. Imagine if instead that the customer API pretty much edits a document directly, like a file on S3 or whatever. And imagine the servers just pull that file every few seconds, WHETHER IT CHANGED OR NOT.
This system is O(1). The whole config can change, or none of it, and the servers don’t even care. They are dumb. They just carry on. This is MUCH MUCH more robust. It never lags, it self-heals very quickly, and it’s always ready for a set of events like everyone changing everything at once. The SYSTEM DOES NOT CARE.
