Azure CDN setup for Multisite azure webapp

Chandu 0

I'm seeking guidance on the optimal CDN configuration for a multi-site Azure Web App protected by an Azure Application Gateway Web Application Firewall (WAF). Our Web App hosts over 10 live websites, each with its unique custom domain. What is the recommended approach for implementing a CDN in this scenario?

Hi Ganesh,

Thank you for your response.

We are hosting Sitecore websites on an Azure multisite web app, which means we are hosting multiple different websites, each with its own custom domain. Additionally, we use the SiteDefinition.config file to direct traffic to the specific websites. Given this setup, what is the best way to configure a CDN? Pls let mee know if you need more info on this.

Hello Chandu,

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

In your scenario, creating a single Azure CDN endpoint with multiple origins is the recommended approach for serving media content from your 20 production websites behind an Azure Application Gateway (WAF v2). Here's why:

Azure Content Delivery Network offers the following key features:

Dynamic site acceleration

Content delivery network caching rules

HTTPS custom domain support

Azure Diagnostics logs

File compression

Geo-filtering

The following are the restrictions for content delivery networks:

ResourceLimitAzure Content Delivery Network profiles25Azure Content Delivery Network profiles25Content Delivery Network endpoints per profile25Custom domains per endpoint25Refer: https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/azure-subscription-service-limits#content-delivery-network-limits
