A company needs to optimize the cost of an AWS environment that contains multiple accounts in an organization in AWS Organizations. The company conducted cost optimization activities 3 years ago and purchased Amazon EC2 Standard Reserved Instances that recently expired.
The company needs EC2 instances for 3 more years. Additionally, the company has deployed a new serverless workload.
Which strategy will provide the company with the MOST cost savings?
To optimize cost for the next 3 years while considering the new serverless workload, the best approach is to purchase Amazon EC2 Standard Reserved Instances for another 3-year term with All Upfront payment to take advantage of the maximum discount. Additionally, purchasing a 3-year Compute Savings Plan with All Upfront payment in the management account will cover any additional compute costs including the new serverless workload, ensuring that the company benefits from the most cost savings.
A Need a Compute Savings Plan for serverless workloads The least expensive way to run EC2 instances for 3 years would be either a Reserved Instance or EC2 Instance Savings Plan.
+1 for 3Y All Upfront RI, which will give best discount ever
A because it is said that 3 years ago they optimized costs and came to that conclusion... so just renew reserved instances and for compute use compute plan because that is the best add for serverless...
Since there are no special requirements in the problem statement other than cost (e.g., workload consistency, specific instance size, future changes), simply select the least expensive plan. Compared to on-demand instances, Reserved Instances (RI) offer discounts of up to 75%, Compute Savings Plans up to 66%, and EC2 Instance Savings Plans up to 72%. In each case, the higher the upfront payment, the greater the discount.
It's clear, RI for EC2 and compute saving for serverless
