 # 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.
