Deployment slot

This article outlines the process of using deployment slot in App service.
A deployment slot in Azure are additional instances of a web application that allow you to create different environments (slots) for testing, staging, or production.
Each slot can have its own configuration, such as AppSettings and Connectionstrings.
The original App Service deployment slot is called the production slot.
Below are the steps for the process:
Go to ugonnaappone, under deployment select deployment slot and click add slot

In the add slot, name it newfeatures and in clone settings from select ugonnaappone, then click add.

Originally ugonnaappone has 100% of the traffic

Then give ugonnaappone-newfeatures 10% traffic and save

During the testing period, if there was no complain in the 10% and there is satisfaction with the feedback then a swap can be done

The source can be added to production by clicking start swap. that is swapping the 10% of the newfeature back to production

Click on refresh it will show that the 10% that was given to the new feature has being swapped to production
