Obviously DevOps is not a product and certainly not a user portal or experience. That being said, I can see how having an integrated user experience to accomplish common tasks across the entire application lifecycle could be of value to developers and operations. But what do you think?
In the interview below I did with Stephen Siciliano, he shows off an example of such an experience in the new Microsoft Azure portal which is currently in preview. Inside the portal within ~15 minutes, we walk through adding a new team code project, edit and commit the code, setup continuous integration and deployment with Azure websites, look at build and deployment history, setup metrics for monitoring the application, and customizing the Azure portal itself.
