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.
Universal CDN or UCDN is a content delivery network by XBT Holding, a global hosting and network solutions provider headquartered in Luxembourg. The company offers a wide array of services, which includes file hosting.
The network map of UCDN is relatively small: according to our information the company has 12 points of presence (PoPs).
