Access AWS resources using Lambda function

Question

How can I configure my lambda function to use different AWS Resources? Can someone guide me through this?

Answer 1

You basically grant permissions to the Lambda function that in turn access other resources using an IAM role. AWS Lambda uses these role while executing the Lambda function, so that you always retain full, secure control of exactly which of the AWS resources it can use. This way you can allow Lambda to use other AWS resources.

Answer 2

You can use AWS Identity and Access Management (IAM) to manage access to the Lambda API and resources like functions and layers. For users and applications in your account that use Lambda, you manage permissions in a permissions policy that you can apply to IAM users, groups, or roles. To grant permissions to other accounts or AWS services that use your Lambda resources, you use a policy that applies to the resource itself.
