There are a variety of instance types to choose from when creating a Cortex cluster. If you are unsure about which instance to pick, review these options as a starting point.
This is not a comprehensive guide so please refer to the AWS's documentation for more information.
Note: you may have limited (or no) access to certain instance types. To check your limits, click here, set your region in the upper right, and type "on-demand" in the search box. You can request a limit by selecting an instance family and clicking "Request limit increase" in the upper right. Note that the limits are vCPU-based no matter the instance type (e.g. to run 4
g4dn.xlarge instances, you will need a 16 vCPU limit for G instances).
