Maintain control This may sound a bit crazy, but if you’re going to own the latency/availability SLA, then you need to ‘own’ as much of the call path as possible. Using asynchronous programming also helps here, as when calls never return you can generate a generic ‘busy signal’ response that always seems to go down better than silence.
