Azure CDN Endpoint poiting to Azure Traffic Manager

Question

I am evaluating a DR situation within Azure for a website which uses Azure CDN. For the same, one of the approaches I am looking into is to have a CDN endpoint configured to point to Azure Traffic Manager. Is it a valid design? Can somebody point me to any DR architectures for Azure which combines Azure CDN with Azure Traffic Manager as I am not finding any specific examples.

Answer 1

Instead of CDN endpoints pointing to Azure traffic manager, you can use Azure Traffic Manager with Azure CDN to load balance among multiple CDN endpoints for failover, geo-load balancing, and other scenarios.

This article provides guidance and an example of how to set up failover with Azure CDN Standard from Verizon and Azure CDN Standard from Akamai profiles.

Main steps:

1. Create two or more Azure CDN profiles and endpoints with different providers.
2. Create an Azure Traffic Manager profile and add your CDN endpoints as External endpoints in the Azure Traffic Manager profile.
3. Set up custom domain on Azure CDN and Azure Traffic Manager

Answer 2

The basic approach is as follow:

• Deploy web apps (or functions) in two different regions
• Replicate data between the same two different regions (eg. storage accounts, databases)
• Configure Traffic Manager to monitor health of the service on the primary site, if health is degraded, fail over to secondary site

This is pretty well documented in this article: https://docs.microsoft.com/en-us/azure/networking/disaster-recovery-dns-traffic-manager
