An organization has setup consolidated billing with 3 different AWS accounts. Which of the below mentioned advantages will organization receive in terms of the AWS pricing?
A.
The consolidated billing does not bring any cost advantage for the organization
B.
All AWS accounts will be charged for S3 storage by combining the total storage of each account
C.
The EC2 instances of each account will receive a total of 750*3 micro instance hours free
D.
The free usage tier for all the 3 accounts will be 3 years and not a single year
The answers provided are crap, but the explanation does share some light on what is the real answer supposed to be. As per link below, alludes to B : https://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/con-bill-blended-rates.html
"The preceding example shows how using consolidated billing in AWS Organizations helps lower the overall monthly cost of storage. If you calculate the cost for each member account separately, the total cost is $7,660 rather than $6,720. By aggregating the usage of the three accounts, you reach the lower-priced tiers sooner. The most expensive storage, the first TB, is charged at the highest price just once, rather than three times. For example, three TB of storage at the most expensive rate of $100/TB would result in a charge of $300. Charging this storage as 1 TB ($100) and two additional TB at $80 ($160) results in a total charge of $260.""
I checked consolidated billing and found this I think it is B which is the correct answer. https://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/useconsolidatedbilling-discounts.html
This questions wording of the cost advantage for combined billing and the answer it suggest does not match up. I am leaning more to "A" there is no cost advantage.
Yes it combines the bills of all account but does not change its cost.
Am I thinking this through correctly?
