CDNetworks has been around since 2000, and is currently headquartered in Seoul. The company has raised capital with Shinhan Private Equity, Goldman Sachs and Oak Investment Partners, and acquired CDN competitor Panther Express in 2009. The company was bought by Japanese Telco KDDI in 2011. The provider has 169 points of presence (PoPs) worldwide.
CDNetworks offers the usual services within the CDN ecosystem, such as DDoS protection, cloud storage, Web Application Firewall (WAF), managed DNS with load balancing and video acceleration.
The CDN provider has a strong presence in emerging Internet markets such as China, Russia, India and South America. The company operates in mainland China and has been doing so for over 10 years. Currently, CDNetworks has 21 PoPs within China, which are mostly concentrated in the east of the country. The company is licensed by the Chinese government, and their CDNetworks China Acceleration service can be an alternative to homegrown CDN providers ChinaNetCenter and ChinaCache.
Similar to China acceleration, CDNetworks has a special focus on Russia. With 16 PoPs across the country, and a partnership with network operator MegaFon, CDNetworks offers a broad range of delivery services in Russia.
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.
