A county platform team must choose between synchronous REST calls and asynchronous events for integrating a tax portal with downstream scanners. When is asynchronous event integration the better choice?
Select an answer to reveal the explanation.
Short Explanation
If the submit page should not crash just because one scanner is down, go async with events. You trade the "answer right now in this HTTP call" feeling for looser coupling and better isolation. That trade-off is the heart of picking REST sync versus event-driven flows.
Full Explanation
Asynchronous event integration reduces temporal coupling so producers continue when consumers are slow or unavailable, improving failure isolation. Synchronous REST is preferable when the caller needs an immediate result in the same request. Cloud+ scenarios ask operators to pick the style that matches coupling and reliability goals rather than treating one pattern as universally best.
