This is the correct framework. I have a $200/month production stack on AWS for work. I have a $2.50 HostSlick for a side project that earns zero dollars.
The side project can be down for a week and nobody calls me at 3am. Match your infrastructure to your sleep requirements.
Mi amigo, for restaurant you need local hosting or CDN. Vietnam ISPs peer badly with EU. Your uncle's customers wait 3 seconds for page load, they close tab, they eat pho somewhere else.
HostSlick EU is wrong geography for Vietnam audience.
Can we return to the original question? Is the deal worth it?
Consensus appears to be: worth it for disposable workloads, not worth it for anything requiring accountability. The 12-month lock-in is the real cost, not the €2.50.
