Overview
Microsoft Azure CDN provides content delivery services through a global network of edge nodes, integrated with Azure’s cloud ecosystem. It serves enterprises, developers, and media companies, offering caching, security, and analytics. The service supports web content, video streaming, and edge compute capabilities. Azure partners with Akamai and Verizon for its underlying infrastructure in some configurations.
Streamroot was a provider of peer-to-peer video content delivery network (CDN) solutions, specializing in optimizing over-the-top (OTT) video streaming for broadcasters and content providers. Founded in 2013, the company developed Streamroot DNA™, a WebRTC-based technology that leveraged end-user devices to reduce bandwidth costs and improve streaming quality. It served clients like France Télévisions, Canal+, and Dailymotion, handling millions of daily video sessions globally. Streamroot was acquired by Lumen Technologies (formerly CenturyLink) in September 2019 and is no longer an independent entity, with its operations integrated or discontinued.
Network & Architecture
Azure CDN operates over 100 points of presence (POPs) globally, with strong coverage in North America, EMEA, and APAC. It leverages Microsoft’s global backbone and partnerships with Akamai and Verizon for optimized routing and peering. The service supports HTTP/3 and dynamic content acceleration. Limited public data exists on specific peering arrangements or regional performance nuances.

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/.

History & Notes
—
Streamroot’s technology was notable for its hybrid approach, combining peer-to-peer delivery with traditional CDN infrastructure to reduce buffering and improve quality in bandwidth-constrained regions. Its acquisition by Lumen Technologies aimed to enhance video delivery in challenging markets like Eastern Europe, Asia Pacific, and Latin America. Some sources suggest Streamroot’s technology may still be integrated into Lumen’s CDN offerings, but no clear evidence confirms active use. Conflicting reports exist about its revenue and status at the time of acquisition, with estimates of sub-$5M in annual revenue in 2019.
