Authenticating
You can access AWS resources by using these types of identities:
- AWS account root user
- IAM Users
- IAM Roles
For our discussion, I will focus on IAM Roles, as that is what AWS Lambda uses to authenticate against different AWS services. An IAM role is an IAM identity that you can create in an AWS account with specific permissions, but that doesn't need to be associated with any specific person. With an IAM role, you can obtain temporary credentials to access different AWS services and resources. An IAM role with temporary credentials is useful in the following scenarios:
- Federated user access
- AWS service access
- Apps running on EC2 infrastructure
