What is Azure app service?
Azure App Service is a fully managed Platform as a Service (PaaS) offering from Microsoft Azure that allows you to build, deploy, and scale web apps, mobile back ends, and RESTful APIs in the programming language of your choice without managing infrastructure.

2a. What is deployment slot?
In Azure App Service, a deployment slot is a feature that allows you to host different versions of your application in separate environments within the same App Service instance. Each slot has its own configuration settings, environment variables, and can be used to test or stage your application without affecting the production version.

Key Benefits:
Staging and Testing: You can deploy your app to a staging slot to test changes before swapping it with the production slot.

Zero-Downtime Deployments: By swapping slots, you can achieve near-instant updates with minimal downtime.

Isolated Environments: Each slot can have different settings, enabling you to test with different configurations.

Easy Rollbacks: If a deployment in production goes wrong, you can quickly swap back to the previous version.

b. Step by step in creating deployment slot

1. Having created the new app with different features by following the step by step process in creating the initial app you will click on deployment slot under deployment

1. For the new app created type 10% at the traffic slot that is out of 100% of the traffic using the one in production let 10% be viewing this to access it if ok then click save

1. Maybe after 3months of testing and everything is ok and you want to replace the one in production with the new one for 100% traffic you will click swap then start swap
