Does Lambda function execution time in Provisioned Concurrency affect ephemeral storage?

0

Hello.

I am currently using the aws pricing calculator to estimate Lambda fees. I am having a problem with the fees for ephemeral storage.

The ephemeral storage fee depends on the amount of ephemeral storage allocated to the function and the execution time of the function measured in milliseconds, according to the official website.

https://aws.amazon.com/lambda/pricing/?nc1=h_ls

Assuming that requests to Lambda are processed using only Provisioned Concurrency, I would have thought that the charge for ephemeral storage would be accounted for. However, when I estimated it using the AWS pricing calculator, it was not accounted for.

I would like to know what the problem is. There are three possible causes.

  1. wrong input in aws pricing calculator
  2. a problem on the aws pricing calculator side
  3. incorrect understanding of how the ephemeral storage fee is calculated

Please refer to the estimate in the link below where the Description is "Storage 10GB All Provisioned Concurrency".

I think the issue is with the pricing calculator. It doesn't even have the option to define the ephemeral storage for provisioned concurrency functions. Also, it doesn't take into account calculation of spillover invocations.

I will raise it to the service team.
