Why Most Azure ARM Templates, Including Microsoft Examples, Are Not Meant for Production
Azure ARM templates, including the ones published by Microsoft, are primarily examples. Their purpose is to demonstrate Syntax, resource structure, and how deployments work. They are not designed to be used directly in Production Environments. Microsoft provides these Templates as building blocks. They show how to define a resource, how dependencies work, and how parameters can be used. That is their purpose. They are not intended to represent complete, reusable deployment solutions. Most publicly available Templates, including those from Documentation and Community Sources, share the same limitations. They are simplified.... Read more...
