For configuration, consider:

JSON (or other) properties files packaged with the Lambda functions
environment variables configured on the Lambda functions

If you really need a common persistent source of configuration so that Lambdas do not need to be re-deployed when a configuration change happens, then consider:

Parameter Store
DynamoDB

For lambda configuration, use AWS Lambda Environment Variables: https://docs.aws.amazon.com/lambda/latest/dg/env_variables.html

If you want same config for multiple lambdas use DynamoDB or any other storage.
