My EC2 Instance does not have the permissions to perform an API call PutObject on S3. What should I do?
A) I should run 'aws configure' and insert my personal credentials, because I have access to PutObject on S3
B) I should ask an administrator to attach a Policy to the IAM Role on my EC2 instance that authorises it to do the API call
C) I should export the environment variables with my creditials on the EC2 instance
D) I should use the EC2 Metadata API call

B) I should ask an administrator to attach a Policy to the IAM Role on my EC2 instance that authorises it to do the API call

IAM roles are the right way to provide credentials and permissions to an EC2 instance
