Q1 :The hourly commitment you fill would typically be based on the on-demand rate rather than the savings plan rate.
Answer : Example :If you spend $800 per day on on-demand EC2 instances and have a savings plan that locks $1000 per day, it means that your daily spending is adjusted based on the savings plan.
Here's how it works:
On-demand EC2 instances: You are spending $800 per day on EC2 instances that are billed at the regular on-demand rates. This spending is not affected by the savings plan.
Savings plan: By locking $1000 per day in a savings plan, you have committed to paying a fixed amount regardless of your actual EC2 usage. This means that even if you only use $800 worth of on-demand instances, you will still be charged $1000 per day because of the savings plan.
In this scenario, the savings plan guarantees that you will not pay more than $1000 per day, regardless of your actual usage. It provides a discounted rate compared to the on-demand pricing, but in this case, the savings plan is not fully utilized since you are spending less than the locked amount. The additional $200 per day is effectively unused in terms of EC2 instances, but you still have to pay for it due to the savings plan commitment.
Q2 :The Monthly payment shown in the picture is on demand price or savings plans? and is it the one that I need to pay every month, or I need to calculate savings plans price based on thise Monthly payment?
Answer: In this case, you do not need to calculate the savings plan price based on the monthly payment. The monthly payment already reflects the savings plan price, and it is the amount you need to pay each month according to your savings plan commitment.
The Hourly commitment is based on the savings plans rate.
The difference between Upfront payment or no Upfront payment is only going to affect to the % discounted (more discount with Upfront payment).
The Monthly payment is the one that you will pay every month (discount is already applied).
For more info check the Savings plans page. Here you can see how the different selections affect in the final discount that you get.
Thanks for the explanation. For example I have several ec2 :
- based on on-demand rate, the total is USD 1.5/hour
- based on savings-plans rate, the total is USD 1/hour So my USD hourly commitment is based on on-demand rate (USD 1.5/hour) or savings-plans rate (USD 1/hour)? if it's based on savings-plans rate, so once I purchase savings-plans, I can accomodate my ec2 resources using those savings-plans rate right?
