Please create a small web application to demonstrate your devops skills.

Its root URL should display a form that accepts three fields as input: Name, Favorite, Color, Cats or Dogs. This form should save the result in a relational database and ensure that Name is unique. 

You can use any technology for this (eg, it could be node.js and sqlite, or python and mysql, or golang and postgres - we don't care, but we may ask you about it).

After you have built this sample application, create an Ansible playbook to deploy it on a cloud.
