Architecture of disaster recovery and high availability of Azure web applications

Microsoft Azure traffic manager allows failover, performance, or weighted round robin methods to determine how a request can be satisfied using Azure App Services. Traffic manager applies the traffic routing method to each request and routing method decides how that request will be served and by which endpoint. Endpoints are nothing but Azure web application in our context. We have two Azure web applications so we can consider them as our endpoint.

• The Round-robin method is known as the Weighted method
• The Performance method is known as the Performance method

To make Azure web application highly available, let's consider a scenario where our PetClinic application is deployed in a different ASP. 

If an ASP is created in...
