Azure App Service

Azure App Service is a Platform as a Service offering that hosts Web applications, the server side of mobile applications, Web services, and cross-application business processes. A simplified view of important components and their dependencies is shown here, with new components (dark) and existing Azure components (light).

App Service includes Web App hosting, a renamed version of the existing Azure Websites service. Mobile App, a renamed and updated version of Azure Mobile Services, will help developers build, deploy, and run the server side of applications for phones, tablets, and other mobile clients.

The Logic App component runs long-running business processes (workflows) on a new workflow platform. The workflows incorporate Web services that run in the API App component.

The API App component hosts Web services (also referred to as microservices) and provides a gateway for their security, load balancing, and other functions. An API App store (not shown) will eventually distribute both commercial API Apps and custom API Apps for customers. The API App service is not currently integrated with the existing Azure API Management service, which also provides security, caching, and other support for Web services. Integration is likely in a future version of Azure App Service.
