Question

A municipal permit portal’s checkout must still return a useful response when the optional recommendations service is down. Which design approach best isolates that failure?

Accepted Answer

Degrade or fail soft on recommendations while checkout continues with a cached or empty suggestion list — Checkout is the main road; recommendations are a side street. When the side street floods, traffic should still move on the main road—with a simpler view—rather than closing the whole city.

Answer

Share one thread pool across checkout and recommendations so both fail together

Answer

Block checkout until recommendations recovers so the page never shows partial data

Answer

Route recommendations through the same process as checkout for tighter coupling
