Click the app URL in the slot's blade.
Auto Swap happens after a short time and the update is reflected at your target slot's URL.This eliminates downtime when you deploy your app.This means that the App Service and 4 additional Deployment Slots will all be hosted in and share the same VM Instance and resources.Restarts the worker processes on the source slot using these aforementioned configuration elements.You can QA your code quite a bit in a test environment but there nothing like running it on a real system or even with real users.See the above screenshots for reference of where the.Swapping Azure casino jack cleveland Web App Deployment Slots Image Credit: Aidan Finn.These requirements could be running SQL scripts or some other post deployment step necessary to fully deploy the latest code.The VM behind each Deployment Slot is the same VM Instance that hosts the production deployment slot. .
Roll back a production app after swap If any errors are identified in production after a slot swap, roll the slots back to their pre-swap states by swapping the same two slots immediately.
When you use the Swap with preview option (see Swap deployment slots App Service does the following: Keeps the destination slot unchanged so existing workload on that slot (such as production) is not impacted.

This allows you to test the new version of the code with the production web apps database before the actual swap and requires a second step to complete the swap over.
You can deploy to the slot from a different repository branch, or an altogether different repository.
