Fair point. I was just thinking about that myself. One big reason is to avoid being charged for outgoing data transfer; with OVH, that's unmetered, with a gigabit port. Also, the OVH box, with the specs I laid out above, costs ~$150 per month. For roughly that same price on EC2, we could get an m5ad.xlarge on-demand instance, with 2 cores, 16 GB of RAM, and a 150 GB SSD. We'd have to add EBS and/or S3 (non-Glacier) storage on top of that, and as noted above, outgoing data transfer.
