A 311 intake API receives ticket spikes during storms and must buffer work so backend workers process requests at their own pace without losing messages. Which AWS service provides that managed queue?
Select an answer to reveal the explanation.
Short Explanation
SQS is the ticket basket on the counter — intake drops requests in, workers grab the next one when ready, and nothing vanishes in the rush. SNS shouts to everyone at once, CloudWatch watches health numbers, and a load balancer spreads live clicks; they are not the durable work queue.
Full Explanation
Amazon Simple Queue Service (SQS) is a fully managed message queue that decouples producers from consumers so spikes can be absorbed and processed asynchronously. That pattern fits storm-time 311 intake. SNS is fan-out pub/sub, CloudWatch alarms notify on metrics, and ELB distributes synchronous traffic — complementary tools, not the queue buffer itself.
