> ... multi region. Cheapest and quickest option if you want to have at least some fault tolerance.
That is simple not true, you have to adapt your application to be multi region aware to start with, and if you do that on AWS you are basically locked-in, and one of the most expensive cloud providers out there.
You're saying it's not true, but do you have another example of a quick and cheap way to do this ?
I'm not saying this can be done in 1 day for 2 cents, I'm saying that it's quick and cheap compared to other options.
> adapt your application to be multi region aware
This vs adapting your application to support multi cloud deployments or go from the cloud to start doing on prem with a dedicated team, you can take your bets.
On aws you can setup route 53 to point to multiple regions based on health check or latency.
