Founded in 1997, Mirror Image Internet is a seasoned service provider with a large portfolio of web and hosting services. The company is principally owned by Xcelera Inc., and is headquartered in Massachusetts, US and has an European sales office in London.
The network map of Mirror Image is not made public on their website, and there is no information on the number of points-of-presence (PoPs). Based on performance comparisons, we think Mirror Image uses the Highwinds network, and add their own intelligence. Note that Mirror Image uses the term “Content Access Point (CAP) facilities” to refer to their PoPs.
Mirror Image Internet hold a variety of patents to protect its core technology. These concern Internet communication, web serving and the distributed selection of content servers.
The company offers features for video streaming and video-on-demand (VOD) through their miPUBLISHER platform. Large file download is also supported. Their control panel ClearVue Control Center includes real-time analytics and the necessary tooling to manage the CDN.
Not to be confused with Amazon Cloudfront, CloudFlare is a San Francisco-based CDN provider founded in 2009.
The company offers a Free plan, which includes a CloudFlare issued SSL certificate. The features included in the Free plan are basic; more become available to Pro, Business and Enterprise customers.
CloudFlare, together with Akamai, Fastly, Highwinds, Level3 and EdgeCast, is part of the Google Cloud Platform CDN Interconnect program. As part of the collaboration, 30 CloudFlare points-of-presence (PoPs) are directly connected to the Google Cloud infrastructure. When a content request comes in from a Google Cloud origin it will route directly through the interconnect between both parties rather than through the public Internet. As a result, latency is reduced for origin requests. Clients using Google Cloud also receive a discount to their egress traffic.
