  5. Platform SLOs advanced

    A checkout service calls the platform's configuration service once per request rather than reading at start-up. The config service degrades for 4 minutes with p99 at 12 s and about 30% of calls erroring. Checkout runs at 500 requests per second with a connection pool of 200. Walk through what happens, and what the platform should ship so this coupling cannot recur.
