That is the starting point though , minimum you need to buy one more for FO/DR if you care about uptime .
It is not once and done you have some continuous costs in either direction.
1. you will not be able to still move all your workloads only your base loads .
2. There will be residual workloads not only if they are spot/flexible bursts but also they are too deeply integrated to Paas offerings .
3. you have to pay for power cooling and network (and its backup) for 5 years .
4. Finally you also have pay for infra team to maintain, this is increasingly difficult (and expensive) to hire and retain .
Don’t get me wrong I would love to be able buy something like this, but the cost economy is pretty steep and 1-2M spends is too early (it is not on oxide, serious hardware costs a ton these days )
