Azure App Service

Azure App Service is a Platform as a Service (PaaS) environment 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 Apps, a renamed version of the existing Azure Websites service. Mobile Apps, 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 Apps component runs long-running business processes (workflows) on a new workflow platform. The workflows incorporate Web services that run in the API Apps component.

The API Apps component hosts Web services and provides a gateway for their security, load balancing, and other functions. API Apps in Azure Marketplace (not shown) will eventually distribute both commercial API Apps and custom API Apps for customers.
