App Service

Quickly and easily create enterprise-ready web and mobile apps for any platform or device, and deploy them on a scalable and reliable cloud infrastructure.

Enabling productivity and innovation for more than 2 million apps and sites on Azure

Quickly build, deploy, and scale web apps and APIs on your terms. Work with .NET, .NET Core, Node.js, Java, Python, or PHP in containers, or running on Windows or Linux. Meet rigorous, enterprise-grade performance and security and compliance requirements with a trusted, fully managed platform as a service (PAAS) that handles more than 60 billion requests per day.

Fully managed service with built-in infrastructure maintenance, security patching, and scaling

Built-in continuous integration and continuous delivery (CI/CD) and zero-downtime deployments

Support for virtual networks, and ability to run in an isolated and dedicated App Service Environment

Rigorous security and compliance standards, including SOC and PCI, for seamless deployments in the cloud, in Azure Government, and on premises

Quickly build web apps and APIs in the cloud

  • Bring your code or container using the framework language of your choice.
  • Run on Kubernetes, anywhere across Azure, on premises, and any CNCF-conformant Kubernetes cluster through Azure Arc.
  • Increase developer productivity with tight integration of Visual Studio Code and Visual Studio.
  • Streamline CI/CD with Git, GitHub, GitHub Actions, Atlassian Bitbucket, Azure DevOps, Docker Hub, and Azure Container Registry.
  • Reduce downtime and minimise risk for app updates by using deployment slots.

Scale web apps on an enterprise-grade service

  • Get high availability with a service-level agreement (SLA)-backed uptime of 99.95 percent.
  • Simplify operations with automatic platform maintenance and security patching.
  • Help protect your applications with Azure Web Application Firewall, and connect through virtual network integration.
  • Deploy isolated web app instances with a single-tenancy model. Use App Service Environment v3 to enforce network access external to your applications.
  • Use Azure Active Directory and other popular identity providers to authenticate and authorise app access.
  • Scale globally across all Azure regions.

Focus investment on app innovation, not on managing infrastructure

"With cloud services, we are able to eliminate all points of failure. We have created process and equipment redundancy so if one server fails, then the other one will continue operating. The switch can be made instantly, and the user doesn't even notice the change."

Hildebrand Almada, IT Infrastructure Co-ordinator


"I choose Azure PaaS products according to my purpose. The good thing about Azure is that each product has a clear concept and a consistent culture of user-friendliness. All products have the same UI design. There is a line of thought that can not be set more finely. There are times when it is difficult to make detailed settings, but it can be said that it is precisely because there are such restrictions that you can concentrate on how to combine them."

Yusuke Suzuki, President and CEO of Growth Architecture & Teams


"Azure didn't let us down. More than that, it gave us a way to assure senior management that we could support this massive, global campaign."

Lennart Boorsma, Digital Marketing Manager, Heineken


"The apps we started with were monolithic, so they didn't scale well. Azure App Service let us break down those apps into components that could be scaled out separately."

Alex Wilhelmsen, Digital Architect


"Our move to .NET Core, Visual Studio Code, TypeScript, and Azure services worked out just like we had planned. Our new website makes us much more agile in supporting Chipotle's primary mission."
