IAM Roles

What is IAM Roles?

IAM Roles are a way to grant permissions to AWS resources without needing to manage long-term credentials like access keys. An IAM role is an identity that you can assume, and when you assume a role, you obtain temporary security credentials. They are commonly used to allow EC2 instances, Lambda functions, and other AWS services to securely access other AWS resources (like S3 buckets or DynamoDB tables) or to allow users from one AWS account to access resources in another account.
