Deployment slots

Deployment slots are separate environments within a web application hosting platform that allow you to deploy and test updates without affecting the live site. Think of them as dedicated staging areas—your "test" slot and your "live" slot. You can deploy changes to the test slot, verify everything works correctly, and then swap it with the live slot when ready. This minimizes downtime, reduces risk, and makes deployment smoother. Deployment slots are especially useful for testing new features, bug fixes, or updates in a safe, controlled manner before making them accessible to all users.
