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.
HolaCDN is the video CDN from Hola, an Israel-based company known for their Hola VPN and peer-to-peer (P2P) technology, and P2P data mining service Luminati.io.
The solution lets customers combine their own CDN with the network of HolaCDN, to optimise video delivery. The delivery process takes place in two phases:
Customers can integrate the CDN with a variety of existing, third-party video players or use the Open Source Hola Player.
HolaCDN does not publish their network map or the amount and locations of their of points of presence (PoPs). Their network does not need to be extensive due to the nature of video loading: only the initial chunk needs to be served out quickly, what follows is less relevant. So, as far as their network goes – we can only guess.
