My uptime monitoring project uses AWS Lambda heavily, almost exclusively https://apex.sh/ping/ https://apex.sh/ping/ — it has been great. I've processed 3,687,727,585 "checks" (requests really) with it, and I only had roughly 1 hour of downtime two years ago in a single region. Since then it has been stable. I have 14 or so regions so doing the same thing with EC2 would have considerable overhead, though I can still imagine many cases where Lambda would not be cost effective, but its integration with Kinesis is fantastic as well, stream processing almost cannot be easier, and while people say Kafka is more cost-effective, with a bit of batching you can get a long way with Kinesis as well.
