Lambda Provisioned Concurrency showing 0 available. But I'm not using any

Question

I have been using my AWS account for more than 4 months. Now, I need to create a Lambda function with provisioned concurrency. However, it gives the following error: ```The maximum allowed provisioned concurrency is 0, based on the unreserved concurrency available (10) minus the minimum unreserved account concurrency (10)``

How can I resolve this issue?

I need help fixing this issue.

Answer 1

The default limit for lambda concurrency is 1000 per account-region across all lambdas. There can possibly be 2 reasons why this is happening:

1. You have other lambda functions in the account that is using the concurrency
2. Your account is new (which is not your case as it is 4 month old) or your account is not having much usage, and aws has set lower limits for both cases.

In either of the 2 scenarios, go to "Quota" service of AWS from your aws account service tab and raise a limit increase request, once the request is served, you can make the changes.
