Build resilience in application access with Application Proxy
Application Proxy is a feature of Azure AD that enables users to access on-premises web applications from a remote client. Application Proxy includes both the Application Proxy service in the cloud, and the Application Proxy connectors, which run on an on-premises server.
Users access on-premises resources through a URL published via Application Proxy. They are redirected to the Azure AD sign in page. The Application Proxy service in Azure AD then sends a token to the Application Proxy connector in the corporate network, which passes the token to the on-premises Active Directory The authenticated user can then access the on-premises resource. In the diagram below, connectors are shown in a connector group.
When you publish your applications via Application Proxy, you must implement capacity planning and appropriate redundancy for the Application Proxy connectors.
