When I used AWS startup credits in 2019, the AWS console made it very difficult to estimate the bill after the credits ran out. I lost a lot of trust in AWS. Also, there were buried mines in the APIs, like the risk of bad logging running up a $70,000/day bill with CloudWatch Logs.

If I could go back and do it again, I would rent a single machine and deploy with ssh (git pull & docker-compose up) and backup to my laptop.
