Before tax-day traffic, a city anticipates a large spike in concurrent Lambda executions for filing helpers. Architects worry reliability will fail when the account hits its concurrency quota. What should they do first?
Select an answer to reveal the explanation.
Short Explanation
Quotas are speed limits, not suggestions. Raise the Lambda concurrency ceiling before tax day and prove it with a load test so the filing helpers don’t get throttled mid-rush.
Full Explanation
Service quotas can throttle otherwise healthy architectures. Raising Lambda concurrent-execution limits before a known traffic event, then validating with load tests, preserves reliability. Recursive invocation tricks, hiding alarms, or ad-hoc single-instance fallbacks without capacity planning do not address the quota risk. Professional designs treat quotas as a reliability dependency for civic peak days.
