Overview

BT (British Telecom), founded in 1846, is a major UK telecommunications provider offering CDN services through its edge infrastructure. It leverages the Streaming Video Alliance’s Open Caching technology, developed with Cisco and Qwilt, to deliver content for 8K video and AR/VR applications. The service targets enterprise customers, particularly those needing high-capacity video delivery. BT operates under its EE brand for mobile services and Openreach for broadband infrastructure. Its CDN is designed to handle modern streaming demands, serving media companies and large-scale businesses.
Google Cloud CDN is a content delivery network integrated with Google Cloud. It sits behind Google Cloud Load Balancing to cache and serve HTTP(S) content from edge locations. Typical users are teams already running workloads on Google Cloud that want CDN caching, signed URLs, modern TLS, and consistent operations across the platform. The service emphasizes policy-driven caching, fast invalidation, and security integration through Cloud Armor. Pricing follows a pay-as-you-go model that varies by region and usage.

Network & Architecture

BT’s CDN uses a global network with points of presence (PoPs) integrated into its extensive telecom infrastructure, though specific PoP counts are not publicly disclosed. It employs Open Caching to turn existing telecom infrastructure into a federated CDN, optimized for low-latency delivery of high-bandwidth content like 8K video. The network benefits from BT’s EE mobile coverage, reaching over 99% of the UK population, and Openreach’s fibre backbone. It has strong regional presence in EMEA, particularly the UK, with peering optimized for European traffic. Coverage in APAC, LATAM, or other regions is less emphasized.
Google Cloud CDN uses Google’s global edge and backbone to terminate HTTP(S) traffic close to end users and fetch from origins over Google’s private network. Coverage spans major regions in North America, Europe, and Asia-Pacific, with additional presence in other geographies. Strengths include integration with Google Cloud Load Balancing, Anycast routing, and private backbone connectivity from edge to origin. Limitations can include fewer CDN-specific knobs than specialist CDNs and feature gaps for advanced video packaging.

Pricing

BT’s CDN pricing is enterprise-focused, typically requiring custom contracts rather than pay-as-you-go or public per-GB rates. No free tier or public pricing details are available. Interested parties must contact BT’s sales team for quotes, as pricing is tailored to large-scale deployments.
Pay-as-you-go pricing with regional rates for cache egress and request charges. Total cost depends on geography, volume, and cache behavior. See cloud.google.com/cdn/pricing for current details.

Integrations & DevEx

BT provides an API-first interface for managing CDN configurations and accessing real-time logs. Documentation is available at https://www.bt.com/about/developers. There is no public mention of Terraform support, SDKs, or specific CI/CD integrations. The focus is on enterprise integrations for media delivery, with limited emphasis on developer-centric tools or migration utilities.
Deep integrations include Google Cloud Load Balancing for traffic ingress, Cloud Armor for WAF and DDoS protections, Cloud Storage and Compute Engine for origins, and Cloud Logging and Monitoring for observability. Infrastructure as code is supported via Terraform, and a REST API enables CI/CD automation.

When it fits

  • Enterprises needing high-capacity video delivery, especially for 8K or AR/VR content, leveraging BT’s telecom infrastructure.
  • UK-based businesses requiring strong regional performance with EE and Openreach integration.
  • Organizations seeking custom enterprise CDN solutions with direct support from a legacy telecom provider.
  • Workloads already hosted on Google Cloud that need an integrated CDN layer.
  • Teams standardizing on Cloud Load Balancing, Cloud Armor, and Cloud Logging.
  • Organizations that want signed URLs, HTTP/3, fast purge, and policy-driven caching.
  • Buyers who prefer Terraform and API-first management across cloud services.

When it doesn’t

  • Small to medium businesses looking for pay-as-you-go or transparent pricing models.
  • Developers needing extensive edge compute, serverless functions, or advanced security features like WAF or DDoS protection.
  • Companies prioritizing global coverage outside EMEA, as BT’s network focus is heavily UK and Europe-centric.
  • Multi-cloud environments seeking provider-neutral or MultiCDN routing.
  • Advanced video workflows needing packaging, DRM, or low-lency live features.
  • Use cases requiring built-in image optimization pipelines.
  • Projects that rely on WebSocket-heavy bidirectional traffic at the edge.
