List all EC2 instance types in a region or AZ [closed]

Answer 1

Well it seems that at least one programmatic way to do this is to query the AWS Pricing API:

#!/bin/bash

curl https://pricing.us-east-1.amazonaws.com/offers/v1.0/aws/AmazonEC2/current/index.json | jq -r '.products[].attributes["instanceType"]' | sort -u | grep '\.'

A gist for this is here, in case of future tweaks: https://gist.github.com/nmagee/b096e6fadf9ac336da7ffdada43f656a

What this is lacking is grouping/specifying by AWS Region, which can be an important distinction -- not every region has all instance type offerings.
