The documentation refers to Azure CDN profile which is going to be deprecated
Azure CDN Standard/Premium from Edgio (formerly Verizon) will be retired on 4 November 2025. Customers of this service must migrate their workload(s) to a comparable service before this date to avoid service interruptions. New Azure CDN from Edgio profiles will no longer be allowed to be created after 15 January 2025. Given that Edgio filed for Chapter 11 Bankruptcy on 9 September 2024, Microsoft cannot guarantee that Edgio will continue to support this service through 4 November 2025. We are actively monitoring the situation and will inform you if any new developments impact this service.
Microsoft’s flagship CDN product, Azure Front Door Standard or Premium, is our recommended replacement and we encourage you to consider migrating your compatible workloads there. View the comparison between Azure Front Door and Azure CDN from Edgio. Azure Front Door compatible workloads can use these step-by-step instructions.
