Known configurations, on the other hand, are specific pre-determined configurations for deploying an environment using ARM templates. These pre-determined configurations are known as T-shirt sizing configuration. The T-shirt sizing acts as an analogy. Similar to the way a T-shirt is available in a pre-determined configuration such as small, medium, and large, ARM templates can be pre-configured to deploy a small, medium, or large environment depending on the need.
