How to Create IAM roles for Amazon EC2?
In this article, we will cover how we can easily create an IAM role use it with an EC2 instance, and provide the required permissions with the S3 policies. These IAM Roles are the identities that we are creating in our account so that we can provide specific permissions to the users. So these Roles provide us the temporary credentials of security for our session.Consider the Scenario in which we want to grant access to our account to third parties that can perform operations such as audits of our resources or consider another scenario in which we want to access users who have identities prior outside the Aws like in our corporate Directory. So we can use the roles for access to users’ services or applications that don’t have access to AWS resources.
