Tata Communications, a company of Indian multinational Tata Group, offers a CDN service with 400 points-of-presence (PoPs) on five continents, in 21 locations. Tata owns and operates an impressive network infrastructure, with their sub-terrestrial and sub-sea network spanning 700,000 kilometers - more than 17 times around the world. According to the company, 24% of the planet’s internet routes are on their network, which grants improved performance and flexibility.
In 2011, Tata Communications acquired BitGravity - a US-based CDN provider founded in 2006. BitGravity. The companies had been in a strategic alliance leading up to the acquisition, and the move was a logical next step for Tata Communications to improve its global CDN offering. Remnants of BitGravity can still be found, such as the Tata Communications CDN support portal.
Tata Communications offers a wide range of CDN features such as live streaming and video-on-demand (VOD), an out-of-the-box online video platform, site acceleration and software delivery. They also provide DDoS and security services, hosting, colocation and transit.
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.
