Article isn't interesting but I checked out the site and whoever wrote <a href="https://usefathom.com/high-traffic" rel="nofollow">https://usefathom.com/high-traffic</a> doesn't know what they're talking about.<p>Lambda isn't infinitely scalable, it's literally finitely bounded by the number of concurrent executions (which has an unpublished hard limit). You could definitely hit this with smthn like page views.<p>Also, the copy brags about SQS FIFO, but FIFO queues are much less scalable than regular queues. They are limited to 20k inflight and 300 TPS for WriteMessage.
