FAQ

Is custom routing worth the engineering effort for a new Alexa skill?
No, the effort is not justified for a single skill; it is warranted when the skill serves millions of users and the latency tail exceeds the 100 ms SLA, because only then does the AIRMatrix‑driven cost benefit outweigh the implementation overhead.

How should I discuss cost savings without sounding like a salesperson?
Not by quoting vague percentages, but by presenting concrete figures—e.g., “AWS Inferentia v2 reduced cost per 1 k inferences by 42 % compared with GPU in our recent Echo Show trial.”

What is the most persuasive way to address reliability concerns in a debrief?
Not by saying “the system is reliable,” but by referencing the fallback‑to‑CPU rule, the 0.05 % error‑rate threshold, and the live‑test results that kept the error rate below that bound for 99 % of requests.
