1. Create a Cluster in PMK using the AWS Cloud Provider. You can follow the tutorial [here](https://platform9.com/docs/kubernetes/get-started-aws).
2. You can then purchase Reserved Instances from the AWS console which matches the attributes of the Instances created via PMK.
3. The Instances created by PMK now will utilize the Reserved Instances Rate.
