How to setup Provisioned Concurrency for AWS Lambda Authorizer

Setup Provisioned Concurrency Access your AWS Lambda configuration for the Authorizer function Navigate to the Provisioned Concurrency settings Enable Provisioned Concurrency by specifying the number of concurrent executions you want to maintain (recommended starting point: 5-10 concurrent executions) Deploy the changes through your infrastructure-as-code pipeline Monitor the performance to adjust the concurrency level as needed Usage Provisioned Concurrency keeps Lambda functions initialized and ready to respond to requests with consistent performance. This is particularly useful for authorizer functions where cold starts can impact authentication response times. The number of provisioned concurrent executions should be adjusted based on your traffic patterns: Start with 5 concurrent executions for moderate traffic Scale up to 10 or more for higher traffic volumes Monitor cold starts and response times to optimize the concurrency level Remember that Provisioned Concurrency incurs additional costs as you're reserving compute capacity. Make sure to balance performance requirements with cost considerations.
