Pricing

Arelion’s pricing model is primarily enterprise-oriented, with custom contracts for wholesale and large-scale customers. No public per-GB pricing is available, and the company does not offer a free tier or pay-as-you-go plans. Pricing details are typically negotiated based on capacity and service requirements. For more information, visit https://www.arelion.com.
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

Arelion’s My Arelion portal supports Open APIs for accessing usage data, support tickets, and service management, enabling integration with customer systems. The portal includes BGP tools and allows self-service for ordering services like Cloud Connect and IP Transit. No specific support for Terraform or CI/CD pipelines is documented. Real-time logs are available through the portal, providing visibility into network performance and service status.
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.
