 # Tutorial: Deploy a PHP, MySQL, and Redis app to Azure App Service
 
-This tutorial shows how to create a secure PHP app in Azure App Service that's connected to a MySQL database (using Azure Database for MySQL Flexible Server). You'll also deploy an Azure Cache for Redis to enable the caching code in your application. Azure App Service is a highly scalable, self-patching, web-hosting service that can easily deploy apps on Windows or Linux. When you're finished, you'll have a Laravel app running on Azure App Service on Linux.

     The `azd up` command takes about 15 minutes to complete (the Redis cache takes the most time). It also compiles and deploys your application code, but you modify your code later to work with App Service. While it's running, the command provides messages about the provisioning and deployment process, including a link to the deployment in Azure. When it finishes, the command also displays a link to the deploy application.

-    Once the command finishes creating resources and deploying the application code the first time, the deployed sample app doesn't work yet because you must make small changes to make it connect to the database in Azure.
