I mean its capex vs opex, assuming a 5 year deprecation period thats 1.2 million isnt too bad, its 10% of their aws spend.
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 )
