Using instance volume as root space instead of EBS volume

Question

As my reserved instance c5ad.2xlarge has instance volume, I want to make use of that for root volume as well as user volume. How do I do that?

Answer

Hi There

Only the following instance types support an instance store volume as the root device: C3, D2, G2, I2, M3, and R3.

You can choose between AMIs backed by Amazon EC2 instance store and AMIs backed by Amazon EBS. We recommend that you use AMIs backed by Amazon EBS, because they launch faster and use persistent storage.
