Pricing

Azure CDN uses a pay-as-you-go (PAYG) model with tiered pricing based on regions and usage. No free tier is offered, and pricing is enterprise-focused. Example: data transfer costs ~$0.08/GB in North America (subject to change). Full details at https://azure.microsoft.com/en-us/pricing/details/cdn/.

Integrations & DevEx

Azure CDN supports Terraform for infrastructure-as-code. SDKs are available for multiple languages (Python, .NET, Java). Real-time logs and analytics integrate with Azure Monitor. Migration tools are provided for importing configurations from other CDNs. The API-first approach simplifies integration with CI/CD pipelines.

When it fits

  • Enterprises already using Azure services, seeking seamless CDN integration.
  • Organizations needing global reach with strong North America and EMEA presence.
  • Developers requiring edge compute with Azure Functions and Terraform support.

When it doesn’t

  • Small businesses or startups looking for a free tier or lower-cost options.
  • Users needing specialized video features like HLS/DASH packaging or DRM.
  • Those requiring detailed public data on network peering or POP specifics.

History & Notes

Telia Carrier was a leading provider with over 320 PoPs in 120 cities, known for its extensive fiber network and DDoS mitigation. The rebrand to Arelion reflects its shift to a standalone entity under Polhem Infra, focusing on global connectivity for enterprises and operators. No service discontinuation was reported, but the Telia Carrier brand is fully deprecated.
