> This is trivial to work out in AWS, I just go to their Reversed Pricing Page [2], look for the total cost for an m5.large (2x VCPU/8GB RAM) instance for 12 months which is $501 (12 x 41.75).
Well, nowadays, you don't buy reserved instances; you buy compute savings plans. And be sure to compare the strengths and limitations of an EC2 Savings Plan versus a general Compute Savings Plan; they have differing characteristics concerning instance type convertibility, regional transfers, and applicable products.
And with Compute Savings plans, its not like an RI where you say "I'm paying for one instance upfront, give me 30% off". You instead commit to a level of spend, in Dollars per Hour. Then they convert that spend into fungible credits that have differing exchange rates depending on the instance type, region, and even compute product. Then, through the magic of the AWS Billing System, you save money.
Very rarely do you come out the other end of AWS Compute consumption with a good understanding of the exact trace of "dollar spent to which compute product?" With products like Fargate, its even worse. Don't get me started on Fargate and its billing characteristics.
I'm nitpicking here. But only because: Nothing is ever as simple as it seems. GCP is just different; I wouldn't classify it as more or less complex.

- PetahNZ 7y agoIsn't savings plans brand new? And can't you still just buy typical reserved instances?
- 013a 7y agoYes, and Yes. Though, as far as I know, there is no financial reason to buy RIs at this point. Check out this comparison table [1]; you get the same savings, but far more flexibility. AWS very rarely removes features. People may still buy RIs because they have corporate or technical processes in place where they make sense. But, from a pure financial standpoint, RIs are inferior to Savings Plans.
