Where the article explains it
Write for the cost — in latency, energy, or both — of attempting the request locally, for the marginal cost of the network round trip once escalation is triggered, and p for the probability a request is judged solvable without escalating.
The passage around this formula
…architecture actually costs, which is easy to gloss over in a design review. Escalation is additive, not a substitution: a request that ultimately needs the cloud still pays for the local attempt first. Write for the cost — in latency, energy, or both — of attempting the request locally, for the marginal cost of the network round trip once escalation is triggered, and p for the probability a request is judged solvable without escalating. If the local attempt always…
