If you choose to run 100% of your workload on a single EC2 VM in us-east-chaos-monkey and put nothing in S3, only local mounted block storage that also disappears when you reboot your on-demand EC2, that is on you.
2 OVH dedicated servers in different countries are still cheaper than one AWS instance.
e.g. I've got servers at OVH SBG-2, Hetzner's Falckenstein, and Online.net's AMS datacenters — the total of which is still almost a magnitude less than the same cost on AWS or GCP (granted, that's including traffic)
Pretty much. Use 5% of the money you saved moving your workload from AWS to OVH to support failover, DR, and backups. You can probably buy like five or six machines of equivalent spec or more.
Not only that, but the OVH load balancer (API gateway) is enormously much cheaper at 2TB of traffic than AWS and they don't charge for the amount of requests.
