Pricing of Amazon EBS

Question

I was just learning about Amazon EBS pricing. I am having a small doubt regarding how the pricing actually works.

If I provision 8GB EBS volume, then delete it and then provision another 8GB EBS volume, all within the same month, will I be charged for 16GB or for 8GB?

This doubt stems from my ambiguous understanding of the word "provision"? I would request you to help me with this. Thank you.

Hello,
EBS pricing is based on per second usage, so you do not need to pay for 30 days. If you used the first 8 gigabyte for one hour, and another 8 gigabytes for another hour, you only have to pay the cost of 8 gigabytes * 2 hours.

The term "provision" in this context refers to the amount of storage capacity you allocate for your EBS volume, regardless of whether you actually use that storage or not.

EG.,

In a region that charges $0.08 per GB-month, you would be charged:

First EBS volume charge(GP3):
($0.08 per GB-month * 8 GB * 3600 seconds / (86,400 seconds/day * 30-day month)) = $0.8

Second EBS volume charge(GP3):
($0.08 per GB-month * 8 GB * 3600 seconds / (86,400 seconds/day * 30-day month)) = $0.8

Total: $ 1.6

Based on your volume size, you can change to 8GB. Also, change 3600 seconds to the number of seconds your volume is provisioned for.

Hey hii

Amazon EBS charges based on the amount of storage you provision per month. This means you pay for the size of the volume you create, regardless of how much data you actually store on it.

* Provisioning means specifying the size of the volume when you create it.
* Deleting a volume releases the provisioned storage, and you stop being charged for it.

In your case:

* You provisioned an 8GB EBS volume.
* You deleted it.
* You provisioned another 8GB EBS volume.

Since you only had an 8GB volume active at any given time, you will be charged for 8GB, not 16GB.

Key Point: The key to understanding EBS pricing is to focus on the size of the volume you create, not the total amount of data stored or transferred.

1. Volume Types: Different EBS volume types (e.g., gp2, io1) have different pricing structures.
2. Data Transfer: If you transfer data to or from your EBS volume, you might incur data transfer charges.
