Should I create IAM role to allow AWS service send events to my default bus

Question

I have setup an example with eventbridge: ec2 -> eventbridge -> sqs.  
  
This example works well, but I didn't create IAM role for ec2, I wonder that does the EC2 need an IAM role to access my default bus or not?

Answer

Got it, thanks

Answer

For AWS Services, such as EC2, to publish events to your default event-bus, they do not need an IAM role. You get these AWS service events by default on your "default" event-bus - You do not need to do anything to receive them.  
  
Please keep in mind, only AWS Services can do this on your default-event-bus. Other identities (users/roles), or other event-bus destinations require authentication to call the "PutEvents" EventBridge API.  
  
Hope this helps!
