@matigo I mean, the VPS that PrivateLog will be running on costs 18,770円 / year for 3 cores and 2 GB RAM. (I have a yearly contract). AWS doesn't really have an equivalent, but maybe a t2.small (1 core and 2 GB RAM). Even with a yearly reserved instance discount, it's $252/year (down from the normal $350.40/year it would cost as an on-demand instance) -- just for the EC2 resources -- current rates put that at 28,513 JPY. :-(
