Is cost of public AMI same as private?

Question

I have both, public and private AMIs stored in my account.  
Is there any difference in cost or they are charged under the same plan?

Accepted Answer

Hi Shantanu Oak,  
  
The charges associated with AMIs do not depend on whether they are public or private. Whether it is public or private does not matter, it depends on the AMI’s storage category for the root device. AMIs are categorized as either backed by Amazon EBS or backed by instance store - https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ComponentsAMIs.html#storage-for-the-root-device. With AMIs backed by instance store, you're charged for instance usage and storing your AMI in Amazon S3. With AMIs backed by Amazon EBS, you're charged for instance usage, EBS volume storage and usage, and storing your AMI as an EBS snapshot.

I hope this helps. Let me know if you have any questions.
