App Service Web Apps is a fully managed compute platform that is optimized for hosting websites and web
applications. This platform-as-a-service (PaaS) offering of Microsoft Azure lets you focus on your business logic
while Azure takes care of the infrastructure to run and scale your apps.
The following 5-minute video introduces Azure App Service Web Apps.
What is a web app in App Service?
In App Service, a web app is the compute resources that Azure provides for hosting a website or web application.
The compute resources may be on shared or dedicated virtual machines (VMs), depending on the pricing tier that
you choose. Your application code runs in a managed VM that is isolated from other customers.
Your code can be in any language or framework that is supported by Azure App Service, such as ASP.NET,
Node.js, Java, PHP, or Python. You can also run scripts that use PowerShell and other scripting languages in a web
app.
For examples of typical application scenarios that you can use Web Apps for, see Web app scenarios and the
Scenarios and recommendations section of Azure App Service, Virtual Machines, Service Fabric, and Cloud
Services comparison.
Why use Web Apps?
Here are some key features of App Service that apply to Web Apps:
Multiple languages and frameworks - App Service has first-class support for ASP.NET, Node.js, Java, PHP,
and Python. You can also run PowerShell and other scripts or executables on App Service VMs.
DevOps optimization - Set up continuous integration and deployment with Visual Studio Team Services,
GitHub, or BitBucket. Promote updates through test and staging environments. Manage your apps in App
Service by using Azure PowerShell or the cross-platform command-line interface (CLI).
Global scale with high availability - Scale up or out manually or automatically. Host your apps anywhere in
Microsoft's global datacenter infrastructure, and the App Service SLA promises high availability.
Connections to SaaS platforms and on-premises data - Choose from more than 50 connectors for
enterprise systems (such as SAP, Siebel, and Oracle), SaaS services (such as Salesforce and Office 365), and
internet services (such as Facebook and Twitter). Access on-premises data using Hybrid Connections and
Azure Virtual Networks.
Security and compliance - App Service is ISO, SOC, and PCI compliant.
Application templates - Choose from an extensive list of application templates in the Azure Marketplace that
let you use a wizard to install popular open-source software such as WordPress, Joomla, and Drupal.
Visual Studio integration - Dedicated tools in Visual Studio streamline the work of creating, deploying, and
debugging.
In addition, a web app can take advantage of features offered by API Apps (such as CORS support) and Mobile
Apps (such as push notifications). For more information about app types in App Service, see Azure App Service
overview.
Besides Web Apps in App Service, Azure offers other services that can be used for hosting websites and web
applications. For most scenarios, Web Apps is the best choice. For microservice architecture, consider Service
Fabric, and if you need more control over the VMs that your code runs on, consider Azure Virtual Machines. For
more information about how to choose between these Azure services, see Azure App Service, Virtual Machines,
Service Fabric, and Cloud Services comparison.
Getting started
To get started by deploying sample code to a new web app in App Service, follow one of the tutorials in the
following dropdown box. You'll need a free Azure account.
NNOOTTEE
You can Try App Service without an Azure account. Create a starter app and play with it for up to an hour--no credit card
required, no commitments.
Introduction to Azure Web Apps for Containers

Web App is a fully managed compute platform that is optimized for hosting websites and web applications.
Customers can use Web Apps for Containers to host web apps natively on Linux for supported application stacks.
The following sections lists the application stacks that are currently supported.
Languages
NODE.JS PHP .NET CORE RUBY
4.4, 4.5 5.6 1.0-1.1 2.3
6.2, 6.6, 6.9-6.11 7.0
8.0-8.1
Deployments

Limitations
The Azure portal shows only features that currently work for Web Apps for Containers. As we enable more features,
they will become visible on the portal.
Some features, such as virtual network integration, Azure Active Directory/third-party authentication, or Kudu site
extensions, are not available yet. Once these features are available, we will update our documentation and blog
about the changes.
Web Apps for Containers is only supported with Basic and Standard app service plans and does not have a Free or
Shared tier. The following are also important restrictions for Web Apps for Containers:
You cannot create Web Apps for Containers in an App Service plan already hosting non-Linux Web Apps.
When creating Web Apps for Containers in a resource group containing non-Linux Web Apps, you must create
an App Service plan in a different region than the existing App Service plan.
Troubleshooting
When your application fails to start or you want to check the logging from your app, check the Docker logs in the
LogFiles directory. You can access this directory either through your SCM site or via FTP. To log the and
stdout
from your container, you need to enable Docker Container logging under Diagnostics Logs.
stderr
You can access the SCM site from Advanced Tools in the Development Tools menu.
