Creating stack from CloudFormation - instance type (t2.small) is not supported

0

Working with simple cloudformation template with Oregon region selected. Using Create Stack from the Designer UI, the stack begins creating resources. When it gets to the instance the error is:

Your requested instance type (t2.small) is not supported in your requested Availability Zone (us-west-2d). Please retry your request by not specifying an Availability Zone or choosing us-west-2a, us-west-2b, us-west-2c. (Service: AmazonEC2; Status Code: 400; Error Code: Unsupported; Request ID: 8b4565c4-86c1-42fc-ba1b-4afc8d28dd96; Proxy: null)

I'm not at all specifying the AZ. I'm having a lot of doubt that any AZ doesn't have a t2.small it can provision.

What is going on? How do I avoid this?

We do have a support guide and a doc on this linked below. One addition recommendation I would make that it does not also suggest is using a newer instance type. You will note that the pricing and performance of a t3 vs a t2 is better to go with later generations. In addition, there are more quantities of current gen than previous generation.

Why am I receiving the error "Your requested instance type is not supported in your requested Availability Zone" when launching an EC2 instance?

  • Thank you Michael. Learning more every step of the way. I now understand that a specific instance type like T2.Small is actually not an option in every AZ. It might be there in some and not others inside of a region.
