Description
Currently, the spot instance type will be chosen based on whichever type in the instance distribution is cheapest. There are scenarios where more expensive instances provide more compute per dollar, in which case it may be advantageous to pay more for the bigger instance.
Relevant docs
- AWS ASG instance weights
- investigation is necessary to see how the cluster autoscaler can handle this
- not currently supported in eksctl config
Notes
- this is just relevant for spot instances, since on-demand instance prices don't change, and scale linearly with instance size within a family
