# Lecture
Boom, the latest version of our room finder application now has authentication (side tutorial to come soon on how to do this); this raises a few DevOps concerns that we will address this week:
- How do we test our application when it is locked down?
- How do we manage authentication across different environments?
- How do we facilitate third-party providers, such as Cloudinary, across different environments?
There is no lecture this week; instead, you should make a start on the the latest side tutorial
