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.
CacheFly is a Chicago-based CDN provider, with over 40 Points of Presence (PoPs) spread over six continents. Next to the usual locations, Cachefly has PoPs in India, Qatar, Egypt and South Africa.
The Cachefly network is optimised for throughput, making it more suitable for the delivery of large files.
Instead of DNS-based global loadbalancing, the company’s CDN infrastructure relies on TCP Anycast routing.
CacheFly offers the usual features in the CDN industry such as instant purge, origin shielding, real-time reporting and sub-accounts. They also offer a 100% availability SLA and 24⁄7 support.
