Set Up Staging Environment Using Azure App Service Deployment Slots

Azure App Service Deployment Slots are a powerful feature that enables you to run multiple instances of your web application in separate environments. This feature allows organizations to implement safe deployment practices, perform A/B testing, and achieve zero-downtime releases, making it essential for businesses that need to maintain high availability while continuously improving their applications.

In this lab, you will deploy a web application to Azure App Service and implement a deployment workflow using deployment slots. You'll learn how to create staging environments, configure slot-specific settings, and perform slot swaps to safely promote changes from staging to production with minimal downtime.

Objectives

Upon completion of this intermediate level lab, you will be able to:

• Deploy a web application to Azure App Service using the Azure CLI
• Create and configure deployment slots for staging environments
• Configure slot-specific application settings that remain with slots during swaps
• Deploy application updates to a staging slot for validation
• Perform slot swaps to promote changes to production with minimal downtime
• Understand the behavior of application settings during slot swaps
