I am trying to do MongoDB on AWS following the AWS deployment guide. It is defaulted to boot up m5.large EC2s. However, I am only experimenting so I want to use a free tier EC2. When I add t2.micro to the allowed values and set it as default I get an error as pictured below.

Is there anyway I can get MongoDB running on AWS with 3 replications using the cloudformation method with free tier t2.micro instances.? If not, any better methods?

The MongoDB on AWS - Quick Start has multiple templates that are deployed.

I notice that the NodeInstanceType is used and defined in multiple templates, presumably with the values passed from the master template to the node templates. Therefore, your changes will probably need to be made on any template that defines the NodeInstanceType parameter. I recommend you check all of the templates for such references.
