2x m5d.4xlarge EC2 instances for 3 year no-upfront reserve pricing is $20,813.76 (You should really do that). But what are you getting 2x m5d.4xlarge instances from the get go? Start with the smallest instance size your app will run on and then add them on one at a time? Need to run 10 servers in the day but only 2 at night? Then configure autoscaling to do that. What happens if you need to expand out into another part of the world? Okay, now you just copy your setup to another Region instead of trying to find another provider in another country. What if your service becomes super popular (You got on the front page of HackerNews), with autoscaling, it just grows automatically. No scrambling to get more servers, it just scales. Don't listen to the "Woe is me!" stories about using the Cloud and feel sorry for these companies. They designed poorly, wrote crappy quick code and paid a price for it.
