Content delivery networks are highly distributed edge-based cloud delivery platforms that provide functionality such as content acceleration, API caching, image optimization, streaming video delivery, web application and perimeter security, as well as edge compute and storage. CDN providers deploy caching, storage and compute nodes in their own and third-party data center locations worldwide to support optimization, agility and security of content delivery.
,Cloud Harmony enables you to measure your network downlink and latency to a range of CDN providers, including Akamai, CacheFly, Limelight, Fastly, CloudFlare, Azure, Amazon CloudFront and Tencent, to name a few. I recently ran such a test and you can see the results in the image above.
