A fireweed-cut fulfillment step must run once, durably, when checkout finishes — even if the worker is down. Which Azure messaging service fits best?
Select an answer to reveal the explanation.
Short Explanation
Checkout commands need a durable mailbox, not a firehose or a pure event fan-out. Service Bus holds the work until a worker is up and completes it.
Full Explanation
Service Bus is the Domain 5 choice for durable business commands and workflows that must survive worker downtime. Event Grid targets discrete event distribution; Event Hubs targets telemetry streams; CDN purge is not a fulfillment queue.
