I could not configure the provisioned concurrency for my Lambda function.

Question

Hi There,
1. I have tried to configure the provisioned concurrency (PC) for my lambda function  to increase the performance of my lambda application.
2. As required i have selected the version of my lambda and tried to enter like 5 in the given input box of the Provisioned concurrency.
3. When i enter the number that input box throws error like **The maximum allowed provisioned concurrency is 0, based on the unreserved concurrency available (10) minus the minimum unreserved account concurrency (10).**
4. What should I do to configure the provisioned concurrency as 100 as i required. 
5. Why im getting The maximum allowed provisioned concurrency is 0 . Guide me to get fix this

Thanks in advance,

Hi,
it seems that you don't have enough quota.

1.- Is the account new? 
2.- Go to [https://us-east-1.console.aws.amazon.com/servicequotas/home?region=us-east-1] (Service Quota) -> AWS Services -> AWs Lambda -> Concurrent executions and as default should be in 1000.
Note: if is not 1000, you can request the increase. follow this to open a request: https://repost.aws/knowledge-center/lambda-concurrency-limit-increase 
3.- If your quota is set to 1000, Follow this steps to increase your lambda concurrences. 
Note: Provisioned concurrency can't be use with the $LATEST version of any function.
