What are DevOps & Ops user stories, or elements in scrum context?
Make sure that your stories are not centered on Operations.  Remember that DevOps is a culture not a role.  Is an "Operations Engineer" really the stakeholder for the story?
Think of the features and business value they provide.  As a stakeholder I want feature so that business value. If you are struggling to identify the business value why are you doing it?
Stories are supposed to be "vertical slices" as opposed to "horizontal slices".  This means that stories should focus on an entire feature, not a layer.  This fits very well in a DevOps culture as your stories can cut across the traditional Development and Operations layers.


You already have some interesting features such as the quality standards. Now you just need to identify who the end stakeholder is, what the business value of this would be, and ensure that you write the story in such a way that people with development, operations, and possibly QA skill sets can work on it.
