Decide when to use Azure App Service


In your research for Tailwind Traders, you've looked at different ways that you can virtualize your application. Another alternative is to deploy your application's front-end websites to Azure App Service, which makes it easy to respond to application demand.

App Service enables you to build and host web apps, background jobs, mobile back-ends, and RESTful APIs in the programming language of your choice without managing infrastructure. It offers automatic scaling and high availability. App Service supports Windows and Linux and enables automated deployments from GitHub, Azure DevOps, or any Git repo to support a continuous deployment model.


This platform as a service (PaaS) environment allows you to focus on the website and API logic while Azure handles the infrastructure to run and scale your web applications.

Azure App Service costs

You pay for the Azure compute resources your app uses while it processes requests based on the App Service plan you choose. The App Service plan determines how much hardware is devoted to your host. For example, the plan determines whether it's dedicated or shared hardware and how much memory is reserved for it. There's even a free tier you can use to host small, low-traffic sites.

Types of app services

With App Service, you can host most common app service styles like:

  • Web apps
  • API apps
  • WebJobs
  • Mobile apps

App Service handles most of the infrastructure decisions you deal with in hosting web-accessible apps:

  • Deployment and management are integrated into the platform.
  • Endpoints can be secured.
  • Sites can be scaled quickly to handle high traffic loads.
  • The built-in load balancing and traffic manager provide high availability.

All of these app styles are hosted in the same infrastructure and share these benefits. This flexibility makes App Service the ideal choice to host web-oriented applications.

Web apps

App Service includes full support for hosting web apps by using ASP.NET, ASP.NET Core, Java, Ruby, Node.js, PHP, or Python. You can choose either Windows or Linux as the host operating system.

API apps

Much like hosting a website, you can build REST-based web APIs by using your choice of language and framework. You get full Swagger support and the ability to package and publish your API in Azure Marketplace. The produced apps can be consumed from any HTTP or HTTPS based client.


You can use the WebJobs feature to run a program (.exe, Java, PHP, Python, or Node.js) or script (.cmd, .bat, PowerShell, or Bash) in the same context as a web app, API app, or mobile app. They can be scheduled or run by a trigger. WebJobs are often used to run background tasks as part of your application logic.

Mobile apps

Use the Mobile Apps feature of App Service to quickly build a back end for iOS and Android apps. With just a few clicks in the Azure portal, you can:

  • Store mobile app data in a cloud-based SQL database.
  • Authenticate customers against common social providers, such as MSA, Google, Twitter, and Facebook.
  • Send push notifications.
  • Execute custom back-end logic in C# or Node.js.

On the mobile app side, there's SDK support for native iOS and Android, Xamarin, and React native apps.
