How severe does this issue affect your experience of using Ray?
- None: Just asking a question out of curiosity
I am wondering about using Ray clusters with AWS EC2 instances and how IAM roles play into this. Our company provides reserved EC2 instances to us under a specific IAM role. If I give Ray access to that IAM role, will it use the existing EC2 instances of the same type, or will it spin up new spot instances?
Is there any way to go about using this strategy for using “reserved” EC2 instances with Ray? The cost is much lower (because we know what to reserve), and it makes it a lot easier with our security team if they know we are not spinning up new instances all the time.
