title: Difference between service role and service role for an EC2 instance?
body: <p><a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_terms-and-concepts.html" rel="nofollow noreferrer">https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_terms-and-concepts.html</a> . I don't understand what the docs are trying to convey.</p>
  
  <p>When you see the first line in the section <strong>service role for an EC2 instance</strong> , It says the "It is a special type of service role that a service assumes to launch an Amazon EC2 instance that runs your application." Later it says "This role is assigned to the EC2 instance when it is launched". Which doesn't make any sense (self-contradicting)</p>
