Web applications architecture design

Today's web apps are expected to be available all day, every day from anywhere in the world, and usable from virtually any device or screen size. Web applications must be secure, flexible, and scalable to meet spikes in demand.

This article provides an overview of Azure web app technologies, guidance, solution ideas, and reference architectures.

Azure provides a wide range of tools and capabilities for creating, hosting, and monitoring web apps. These are just some of the key web app services available in Azure:

  • Azure App Service enables you to easily create enterprise-ready web and mobile apps for any platform or device and deploy them on a scalable cloud infrastructure.
  • Azure Web Application Firewall provides powerful protection for web apps.
  • Azure Monitor provides full observability into your applications, infrastructure, and network. Monitor includes Application Insights, which provides application performance management and monitoring for live web apps.
  • Azure SignalR Service enables you to easily add real-time web functionalities.
  • Static Web Apps provides streamlined full-stack development, from source code to global high availability.
  • Web App for Containers enables you to run containerized web apps on Windows and Linux.
  • Azure Service Bus enables you to integrate with other web apps using loosely coupled event-driven patterns.
