Deployment slots are live apps with their own host names. App content and configurations elements can be swapped between two deployment slots, including the production slot.
Deploying your application to a non-production slot has the following benefits:
- You can validate app changes in a staging deployment slot before swapping it with the production slot.
- Deploying an app to a slot first and swapping it into production makes sure that all instances of the slot are warmed up before being swapped into production. This eliminates downtime when you deploy your app. The traffic redirection is seamless, and no requests are dropped because of swap operations.
- You can automate this entire workflow by configuring auto swap when pre-swap validation isn't needed.
- After a swap, the slot with previously staged app now has the previous production app. If the changes swapped into the production slot aren't as you expect, you can perform the same swap immediately to get your "last known good site" back.
