“Why run on lambda instead of fargate? Oops, we won’t tell you.” - AWS

This is going to throw unknowing readers for a loop, because it's a comment trying to be cheeky.

Simply put: Fargate/ECS/EC2+EB = long running tasks

Lambda = Short burst tasks with a max life of 15 minutes

Running a lambda 24/7 will nuke your credit card. Using Fargate for a scheduler/cron job that only runs 4 times a day will nuke your credit card. Use the right tool for the right job.

AWS datapipeline is likely the best solution for a longer running batch that gets run 3-4 times a day.

It's definitely an option. Wrapped services are almost always more expensive, so careful attention to pricing details is needed.

The bulk of the cost here is usually on the EC2 side. The main extra cost is the price it takes your runner EC2 instance(s) to bootstrap - ie usually about 2-3 minutes. Can be mitigated by using prepaid discounts, etc.
